APPLY(1) FreeBSD General Commands Manual APPLY(1)
NAME apply - apply a command to a set of arguments
SYNOPSIS apply [-a c] [-d] [-#] command argument ...
DESCRIPTION The apply utility runs the named command on each argument argument in turn.
Character sequences of the form "%d" in command, where `d' is a digit from 1 to 9, are replaced by the d'th following unused argument. In this case, the largest digit number of arguments are discarded for each execution of command.
The options are as follows:
-# Normally arguments are taken singly; the optional number # specifies the number of arguments to be passed to command. If the number is zero, command is run, without arguments, once for each argument.
If any sequences of "%d" occur in command, the -# option is ignored.
-a c The use of the character `%' as a magic character may be changed with the -a option.
-d Display the commands that would have been executed, but do not actually execute them.
ENVIRONMENT The following environment variable affects the execution of apply:
SHELL Pathname of shell to use. If this variable is not defined, the Bourne shell is used.
FILES /bin/sh default shell
EXAMPLES apply echo * is similar to ls(1); apply -2 cmp a1 b1 a2 b2 a3 b3 compares the `a' files to the `b' files; apply -0 who 1 2 3 4 5 runs who(1) 5 times; and apply 'ln %1 /usr/joe' * links all files in the current directory to the directory /usr/joe.
HISTORY The apply command appeared in 4.2BSD.
