UNQUOTE(1) General Commands Manual UNQUOTE(1) NAME unquote -- execute a program with safely quoted arguments SYNOPSIS unquote [-f fields] [-0 | -N] [-hnpqRVv] fields command [args ...] DESCRIPTION The unquote utility executes command with the specified arguments after unquoting the specified fields. The fields argument, which may be specified in various ways, is a colon-delimited list of numbers, fol- lowing the Unix/C convention that command is argument 0, args starting from 1. Each argument in the list is interpreted as a hex-encoded string, with two hex digits for each character. The list of arguments to be quoted is constructed in the following way: • The environment variable UNQUOTE_ARGS is examined, and if it is set, the string it contains is parsed as a fields list. • Any -f arguments are parsed and added to the (possibly empty) list, not replacing any of its contents. • The first non-option argument, fields, is examined, and also added to the (possibly empty) list, not replacing any of its contents. The following options are available: -0 If -n is also specified, separate arguments in the output with ASCII NUL characters (character code 0). This option cannot be used at the same time as -N. -f fields Specify a list of args to unquote before executing command. -h Display a short help message and exit. -N If -n is also specified, separate arguments in the output with a newline. This option cannot be used at the same time as -0. -n Do not actually execute command, just print out its expanded form. -p Do not search the environment variable PATH for the specified command. If this flag is specified, unquote uses execv(3) in- stead of execvp(3) to execute the command. In other words, command should be a full path to an executable program; PATH is not searched. -q Quiet operation; even more quiet when more than one -q flag is specified. -R Do the exact opposite of normal operation: quote the arguments instead of unquoting them. Useful when one needs to test a program with a long quoted argument. -V Display version information and exit. When combined with one or more -v switches, unquote also attempts to display informa- tion about its build environment. -v Verbose operation; even more verbose when more than one -v flag is specified. ENVIRONMENT The following environment variables affect the execution of unquote: UNQUOTE_ARGS Specify a list of args to unquote before executing command. FILES None relevant in the present version. EXAMPLES unquote 1 /bin/echo 54657374 Display `Test'. unquote 2 /usr/local/vpopmail/bin/vadduser testuser 255465737424 Add a vpopmail user `testuser' with a password `%Test$'. BUGS Should command-line fields and -f arguments override UNQUOTE_ARGS? HISTORY Written by Peter Pentchev in 2001. AUTHORS Peter Pentchev <roam@ringlet.net>. FreeBSD July 7, 2003 UNQUOTE(1)
