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 a*"
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 BSD 4.2 .

BUGS

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.
