APPLY(1) FreeBSD General Commands Manual APPLY(1)

apply a command to a set of arguments

apply [-a c] [-d] [-#] command argument ...

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.

The use of the character ‘%’ as a magic character may be changed with the -a option.
Display the commands that would have been executed, but do not actually execute them.

The following environment variable affects the execution of apply:
Pathname of shell to use. If this variable is not defined, the Bourne shell is used.

default shell

is similar to ls(1);
compares the `a' files to the `b' files;
runs who(1) 5 times; and
links all files in the current directory to the directory /usr/joe.

The apply command appeared in 4.2BSD.

Rob Pike

Shell metacharacters in command may have bizarre effects; it is best to enclose complicated commands in single quotes ('').

The apply utility does not recognize multibyte characters.
