LOOKAT(1) User Commands LOOKAT(1) NAME lookat - Un*x file viewer SYNOPSIS lookat [ --help ] [ filename ] [ dir_name ] DESCRIPTION "lookat" (or "bekijk" in the Dutch version) is a program to view Un*x text files and manual pages. Under DOS I used list.com to view text files. I didn't find such a program under my favorite OS, GNU/Linux. The standard Un*x utilities ( more, less, view ...) weren't userfriendly enough. For this reason I created "lookat". OPTIONS --help This option displays a help text. file_name view file_name dir_name change the current directory to dir_name BUGS None known yet, when you find one you let me know :-) USAGE There are four ways to start lookat : * by just typing 'lookat', after the program is started you can select the file you want to view. if there is already data on stdin, lookat will read the from stdin, and display the contents of stdin example: ls | lookat * type 'lookat dir_name', change the current directory to dir_name. When the program is started you can select the file you want to view. * by typing 'lookat <filename>', the file with <filename> will automati- cally be loaded. * in combination with "man" examples : man -Plookat ls export PAGER=lookat; man ls If you like "lookat" as your manual page viewer you can put the next lines in your /etc/profile alias man="man -Plookat" After you have loaded a file, the following keys can be used: Keys: <-, C-b : move left / back ->, C-f : move right / forward arrow up, C-p : move up / previous line arrow down, C-n : move down / next line PgUp, u : move up a screen PgDwn, d : move down a screen HOME : go to the beginning of a line END : go to the end of a line o : open a new file t,< : go to top (start of file) b,e,> : go to the last line (end of file) g : go to a line number /,z,s,f : search for a string F3, n, c, v, : continue search F9 : menu ALT+f : file menu ALT+g : go menu ALT+s : search menu ALT+h : help menu F10,ESC,q : quit program F1,h,? : view this help file r : rebuild screen When you press F9 you get access to the pull-down menus, most of the func- tions are also available through the keyboard (see above). File|Open or 'o': When you select this function you get a window, at the left side of the window you get the files of the current directory. By selecting a file it will be loaded. At the right size of the window you see the directories, by pressing the TAB key you are able to switch be- tween the file and the directory selection. By selecting a directory with ENTER you change the current directory. With the ESC key you cancel the file open operation. File|Quit or 'F10,ESC,q': Quit program. Go|to begin or 'b': Move to the first line of the file. Go|to end or 'e': Move to the last line of the file. Go|to line or 'g': With this function you are able to move to a certain line number. After you have selected this function you get a window which asks you to give a line number. With ESC you cancel the operation, by pressing the TAB key you can use the [ OK ] and [ Cancel ] but- tons. Go|to end of a line or 'END': Move to the end of a line. Go|to the beginning of a line or 'HOME': Move to the beginning of a line. Search|for a string or '/,z,s,f' With this function you can search for a string in the file. The searching will start from the current line (the first line on the screen) to the last line in the file. After you select this function you will see a window which asks you to give a string. The searching can been done on two ways, with or without case sensitivity. By pressing the TAB key you can select -with SPACE or ENTER- how to search at [ ] Case sensitive With the TAB key you are also able to use the [ OK ] and [ Can- cel ] buttons. Search|from beginning of the file See above, the searching will start from the first line. Search|Again or 'F3' Search for the last string again.

View this help file. Help|Keys ... Shows a list with the keys you can use in "lookat". Help|About Shows information about the program (version ,etc.). CONFIGURATION Note: The format of the configuration file has changed, please remove the "=" sign. The old configuration files will still work, but may not be supported in the future. lookat uses two configuration files a global configuration file ( /usr/lo- cal/etc/lookat.conf ) and a user configuration file ( $HOME/.lookat ) if the user's configuration file exists the global is ignored. If the configuration files aren't available the defaults are used. CONFIGURATION DIRECTIVES cursor on|off turn the cursor on / off give_notice on|of give notice on exit on / off .[extension] "external cmd" create a new type If a filename matches a type the external command will be used to open the file. A typical usage are gzipped files: .gz "gzip -cd" The type order is important lookat will compare the filename with the types starting with the first type and continues until a type matches a filename. So if you want to define a type for ".gz" and ".tar.gz" files you have to put the .tar.gz type first. color object foreground background [ attribute ] If your terminal supports colors, this directive can be use to mod- ify the color of certain objects. Valid objects are: view, view_bold, view_italic, main_menu, main_menusel, main_menuhot, main_menuhotsel, status_bar, win1, win1_edit, win1_menu, win1_menusel, win1_menuhot, win1_menuhotsel, win2, win2_edit, win2_menu, win2_menusel, win2_menuhot, win2_menuhotsel, view_found. Valid colors are: white, black, green, magenta, blue, cyan, yellow, red. Valid attributes are: normal, bold, underline, reverse, and stand- out. mono object foreground_attribute [ background_attribute ] If your terminal doesn't support color, you can still assign fore- ground and background attributes to certain objects.
