NAME
icesh - control window properties and the IceWM window manager
SYNOPSIS
icesh OPTIONS|ACTIONS+
DESCRIPTION
icesh provides two types of commands:
1. Commands to directly interact with icewm:
These are listed in the section "MANAGER ACTIONS" below. They are
easy to use, because they don't require to select one or more
windows. For example, "icesh restart" will restart icewm and "icesh
clients" lists the applications that are managed by icewm.
2. Commands that operate on a selection of windows:
See the section "WINDOW ACTIONS" below. For example, "icesh close"
is a request to close a window, but which window? Now icesh will
turn the mouse pointer into a crosshair. Click on a window and a
close request will be sent to that application.
The power of icesh lies in its ability to programmatically select
one or more windows and operate on that selection. This can be
used in scripts and in icewm-keys(5) to define your own window
management hotkeys. For example, to immediately close all xterm
windows do "icesh -c xterm close".
There are a dozen "SELECT OPTIONS" to select windows. They start
with a '-' or a '+'. The '-' starts a new selection, while the '+'
adds more windows to an existing selection.
This selection of windows can be reduced by "FILTER OPTIONS".
These remove unwanted windows from the current selection. Multiple
filter options can be given. For example, "icesh -c xterm -W this
close" will close only those xterms that are shown on the current
workspace. The xterms on other workspaces are filtered out by the
"-W this" filter option.
There is no limit to the number of commands, selections, filters and
actions that you can give to a single icesh command. They are
processed and evaluated one by one from left to right. This makes
icesh a small declarative programming language. Have a look at some
examples near the end of this document.
OPTIONS
icesh recognizes the following options:
SELECT OPTIONS
Select options specify the window or windows to which subsequent
actions apply. If none is given, but an action does require a window,
then a selection crosshair is shown to select the desired window
interactively. The manager actions do not require window options.
The following options select one or more client windows. If needed,
they can be repeated for successive actions.
-a, -all
Selects all client windows of the window manager.
-f, -focus, +f, +focus
Selects the application window that is currently focused. The
option with minus sign replaces the existing selection with the
focused window. With a plus sign the focused window is added to an
existing selection.
+g, +group
Extend the current selection with client windows that belong to the
same application window group.
-r, -root, +r, +root
Selects the root window. The option with minus sign replaces the
existing selection with the root window. With a plus sign the root
window is added to an existing selection.
-s, -shown
Selects all client windows that are on the current workspace.
-t, -top
Selects all toplevel windows from the display unconditionally.
This includes windows that have never been mapped and windows with
the override redirect bit set to evade management.
-w, -window, +w, +window WINDOW_ID
Specifies the identifier of the window, WINDOW_ID, for which the
action applies. Special identifiers are root for the root window
and focus for the currently focused window. The option with minus
sign replaces the existing selection. With a plus sign the window
is added to an existing selection.
-x, -xembed
Selects all windows that are embedded using the XEMBED protocol.
+c, +class CLASS
Extend the current selection with client windows that have a
WM_CLASS property equal to CLASS. This is the resource instance and
class name. If CLASS contains a period, only windows with exactly
the same WM_CLASS property are matched. If there is no period,
windows of the same class and windows of the same instance are
selected.
+C, +Class
Extend the current selection with client windows that have a
WM_CLASS property similar to the already selected set of windows.
-D, -Dockapps
Selects all Dockapp applications that are managed by icewm.
+P, +Pid
Extend the current selection with client windows that have the same
process identifier as one of the selected windows.
-T Selects the IceWM taskbar.
-A, -Await
Wait for one or more new client windows to appear and make that the
new selection.
FILTER OPTIONS
The following options filter the currently selected set of windows. If
no previous select option was given then a -all option is implicitly
assumed to filter all client windows.
-c, -class CLASS
Filters the set of windows on their WM_CLASS property. This is the
resource instance and class name. If CLASS contains a period, only
windows with exactly the same WM_CLASS property are matched. If
there is no period, windows of the same class and windows of the
same instance (aka. -name) are selected.
-l, -last
Filter clients and keep only the most recent client.
-m, -machine HOST
Filters clients by host name. Clients with a WM_CLIENT_MACHINE
property equal to HOST are selected.
-n, -name NAME
Filters clients by _NET_WM_NAME or WM_NAME. NAME matches any part
of the property value. To match at the beginning use a "^" prefix.
To match at the end use a "$" suffix.
-p, -pid PID
Filters clients by process ID. Clients are selected that have a
process ID of PID, when libXRes is at version 1.2, or that have a
_NET_WM_PID property equal to PID.
-u, -unmapped
Filter clients and keep those that are currently not viewable.
These are hidden, minimized, rolled-up, or on another workspace.
-v, -viewable
Filter clients and keep only those that are currently viewable.
These clients are mapped on the current workspace.
-k, -kovered
Filter clients and keep only those that are currently viewable and
that are at least partially covered by another viewable window.
-G, -Gravity GRAVITY
Filters clients by the window gravity field of the WM_NORMAL_HINTS
property. Clients with a gravity equal to GRAVITY are selected.
If GRAVITY starts with an exclamation mark then the filtering is
inverted.
-L, -Layer LAYER
Filters clients by GNOME window layer, which can either be a layer
name or a layer number. See EXPRESSIONS below. If LAYER starts with
an exclamation mark then the filtering is inverted.
-N, -Netstate STATE
Filters clients by EWMH window state. Clients that have at least an
EWMH window state of STATE are selected. This state refers to
details like MINIZED or MAXIMIZED. See EXPRESSIONS below. If STATE
starts with an exclamation mark then the filtering is inverted. A
question mark "?" filters clients with any bit set in STATE.
-P, -Property PROP[=value]
Filters clients by property. Clients that have a property PROP are
selected. If the optional value is given, the match succeeds only
if PROP is a string, window, cardinal, or atom, with a value equal
to value. The filtering is inverted if PROP starts with an
exclamation mark.
-R, -Role ROLE
Filters clients by WM_WINDOW_ROLE. Clients that have a
WM_WINDOW_ROLE property value equal to ROLE are selected. The
filtering is inverted if ROLE starts with an exclamation mark.
-W, -Workspace WORKSPACE
Filter clients by workspace. Workspace WORKSPACE is either a
workspace name, or a workspace number counting from zero, or the
word "this" for the current workspace, or the word "All" for all
workspaces. If WORKSPACE starts with an exclamation mark then the
filtering is inverted.
-X, -Xinerama MONITOR
Limit clients by RandR/Xinerama monitor. Only operate on clients
that are displayed on MONITOR, where MONITOR can be "All" for all
monitors, "this" for the monitor where the active window is
displayed, or a monitor number starting from zero. See the output
of "randr" or "xinerama" below.
-Z, -Zerminal
Keep only terminals: clients that have forked a shell.
GENERAL OPTIONS
The following options are identical for every IceWM command.
-d, -display DISPLAY
Specifies the X11 DISPLAY. If unspecified, defaults to $DISPLAY.
-h, --help
Print a brief usage statement to stdout and exit.
-V, --version
Print the program version to stdout and exit.
-C, --copying
Print copying permissions to stdout for the program and exit.
-q, --quiet
Don't complain if no matching windows could be found.
ACTIONS
icesh expects one or more action arguments. There are two kinds of
actions: window actions and manager actions. The first operates on the
selected windows. The second directly interacts with the icewm window
manager.
WINDOW ACTIONS
The following actions affect the selected window or windows.
activate
Activate the window, aka. to focus.
close
Send a close request to the client that created the window.
kill
Force an immediate close down of the client that created the
window.
id Print window identifiers for the selected windows.
pid Print process identifiers for the selected windows.
list
Show window details, like geometry and names.
lower
Lower the window.
raise
Raise the window.
above
Stack the window above others.
below
Stack the window below others.
rollup
Rollup the specified window.
fullscreen
Set the window to fullscreen.
maximize
Maximize the window.
horizontal
Maximize the window only horizontally.
vertical
Maximize the window only vertically.

Hide the window.
unhide
Reveal the window.
skip
Don't show the window on the taskbar.
unskip
Do show the window on the taskbar.
sticky
Show the window on all workspaces.
unsticky

urgent
Set the urgency flag to flash the task button.
resize WIDTH HEIGHT
Resize window to WIDTH by HEIGHT window units. For text based
applications like terminals, a window unit is the size of a single
character cell.
sizeto WIDTH HEIGHT
Resize window to WIDTH by HEIGHT pixels. If WIDTH or HEIGHT ends
with a percent sign "%", then they refer to a percentage of the
desktop work area. For instance, "sizeto 50% 100%" resizes to half
the desktop width and whatever height is available above or below
the taskbar.
sizeby WIDTH HEIGHT
Resize window by WIDTH by HEIGHT pixels. If WIDTH or HEIGHT ends
with a percent sign "%", then they refer to a percentage of the
current window size. For instance, "sizeby 50% 200" increases the
width by 50% and increases the height by 200 pixels.
move X Y
Move the selected window or windows to the screen position X Y. To
specify X or Y values relative to the right side or bottom side
precede the value with an extra minus sign, like in "move -+10
--20". When X or Y end with a percent sign "%", they refer to a
percentage of the desktop work area.
moveby X Y
Displace window by X Y pixels.
center
Position the window in the center of the desktop work area.
left
Position the window against the left side of the desktop work area.
right
Position the window against the right side of the desktop work
area.
top Position the window against the top side of the desktop work area.

Set the icon title to TITLE.
getIconTitle
Print the icon title.
setWindowTitle TITLE
Set the window title to TITLE.
getWindowTitle
Print the window title.
setGeometry GEOMETRY
Set the window geometry to GEOMETRY. This geometry should be
specified in a format that can be parsed by XParseGeometry(3).
Negative offsets are with respect to the bottom or right side of
the screen. Use "+-" for a truly negative position.
getGeometry
Print the window geometry.
setClass CLASS
Set the resource name and class to CLASS, which should be a
resource name and a resource class connected by a dot. To preserve
either the existing name or class, use a percentage sign for that
part.
getClass
Print the resource name and class.
netState [STATE]
If STATE is omitted then it shows the EWMH window state. If STATE
starts with a "+" then flags in STATE are appended to the existing
EWMH window state. If STATE starts with a "-" then flags in STATE
are removed from the existing EWMH window state. If STATE starts
with a "^" then flags in STATE are toggled with respect to the
existing EWMH window state. If STATE starts with a "=" then the
EWMH window state is set to STATE. See EXPRESSIONS below. A list of
EWMH flags can be found in the output of "icesh symbols".
setLayer LAYER
Move the specified window to another window layer. See EXPRESSIONS
below for a list of LAYER symbols.
getLayer
Print the window layer for the specified window.
setWorkspace WORKSPACE
Move the specified window to another workspace. Select the root
window to change the current workspace. If WORKSPACE is "All" then
the specified window becomes visible on all workspaces. Specify
"this" for the current workspace, "next" for the subsequent
workspace or "prev" for the preceding workspace.
getWorkspace
Print the workspace for the specified window.
opacity [OPACITY]
Print the window opacity if OPACITY is not given, otherwise set the
window opacity to OPACITY.

Set the IceWM tray option for the specified window to TRAYOPTION.
See IceWM tray options, below, for TRAYOPTION symbols.
getTrayOption
Print the IceWM tray option for the specified window.
setNormalGravity GRAVITY
Set the window gravity field in the WM_NORMAL_HINTS property for
the specified window to GRAVITY. See below for GRAVITY symbols.
getNormalGravity
Print the window gravity from the WM_NORMAL_HINTS property for the
specified window.
setWindowGravity GRAVITY
Set the window gravity for the specified window to GRAVITY. See
below for GRAVITY symbols.
getWindowGravity
Print the window gravity for the specified window.
setBitGravity GRAVITY
Set the bit gravity> for the specified window to GRAVITY. See
below for GRAVITY symbols.
getBitGravity
Print the bit gravity for the specified window.
motif [funcs FUNCTIONS | decor DECORATIONS | remove]
Query, set or modify the "_MOTIF_WM_HINTS" property for the
specified window. Without arguments motif will show the current
value, but only if the window has such a property. The property can
be removed or reset with the remove argument. With funcs and decor
individual fields of this property can be enabled or disabled. If
FUNCTIONS or DECORATIONS starts with a minus or plus sign then the
existing value is modified, otherwise it is set to the new value.
Note that if "All" is set, other set fields are disabled and
cleared fields are enabled.
borderless
Hide the frame borders and title.
bordered
Show the frame borders and title.
denormal
Remove the WM_NORMAL_HINTS property, if it exists. This lifts
font-size restrictions on resizing, especially for terminals.
prop PROPERTY
Print the value of property PROPERTY, if it is present.
properties
Print all properties and their values.
frame
Print the identifier of the window frame.
extents
Print the window identifier and the frame border sizes: left,
right, top and bottom.
focusmodel
Print the ICCCM focus model as advertised by the client window.
This is either Locally, Passive, Globally or NoInput.
override [0|1]
Print the override redirect status for the window, or if either 0
or 1 is given, then disable or enable the override redirect status.
tabto label
Move the windows as tabs to a frame that has "frame" label label.
Such a frame is created if needed.
untab
Move each window to its own frame, if it is currently tabbed.
loadicon image.pam
Load an icon from file, which must be in the PAM image format, with
dimensions at most 256, a depth of 4, and type RGB_ALPHA.
saveicon file000.pam
Save an icon to a new file in the PAM image format. Digits are
increased to generate a unique new filename for each window.
usertime
Show the time of last user interaction in milliseconds.
click window-x window-y button
Send a button press and release event at position (window-x,
window-y). A negative position is relative to the bottom right
corner. The mouse pointer is warped to the position before sending
the events. The button number should be between 1 and 5 inclusive.
monitors top bottom left right
This sets the monitors to use for fullscreen. Top, bottom, left,
and right are indices of the icesh xinerama command.
spy Observe the selected windows and report any changes. This includes
focus, visibility, position, size and all window properties. To
monitor all of the protocol request messages that client
applications may send to icewm, also spy on the root window.
stacking
Sort the list of windows from topmost to bottom-most.
reverse
Reverse the order of the list of windows.
switchmenu
Output the list as a menu for icewm's QuickSwitch. This action is
to be used in a switchkey directive in the "keys" file.
print format
For each window in the selection, print a line according to format.
Here common backslash-escapes are recognized as well as the
following percent formatting options:
% A literal percent sign.
h The window height.
w The window width.
x The window x-position.
y The window y-position.
g The window geometry.
i The window identifying handle.
o An icon name.
p The process-ID of the window application.
c The WM_CLASS property of the window.
m The WM_CLIENT_MACHINE property of the window.
t The window title.
W The current workspace of the window.
Each percent format option may start with a minus sign for
left-alignment and have a numeric field width.
MANAGER ACTIONS
The following actions control the IceWM window manager and therefore do
not require a window select or filter option:
listWorkspaces
List the names of all workspaces.
current
Show the number and name of the current workspace.
goto WORKSPACE
Change the current workspace to WORKSPACE. Specify "next" for the
subsequent workspace or "prev" for the preceding workspace.

x11time
Show the current X11 server time in milliseconds.
sync
Synchronize with the IceWM window manager. That is, wait for icewm
to process all previous actions.
symbols

CONDITIONALS
Icesh supports "if-then-else" expressions. The full syntax is:
if selection
then
actions
elif selection
then
actions
else
actions
end
Where "selection" is a sequence of selection and filtering options,
which evaluates to true when it is non-empty. That is, if one or more
windows fulfilled the condition. If it is empty, then its "actions"
clause is ignored and the subsequent "elif" or "else" clause is tried
or taken. Each clause is optional.
Whenever a selection condition evaluates to false, the window selection
that existed before the "if" clause is immediately restored. This also
happens after an "end" clause.
EXPRESSIONS
Some of the window actions require one or two EXPRESSION arguments.
EXPRESSION ::= SYMBOL | EXPRESSION { "+" | "|" | "-" } SYMBOL
This says that an expression is either a SYMBOL or an expression which
is combined with an operator to a SYMBOL. In other words, an expression
is a sequence of symbols, which are combined using operators, where an
operator may be a plus, a vertical bar or a minus.
Each SYMBOL may be either a number or a named symbol from one of the
following applicable domains, depending upon the context in which it is
