APPLY(1)                    General Commands Manual                   APPLY(1)

NAME
       apply - apply a command to a set of arguments

SYNOPSIS
       apply [ -ac ] [ -n ] command args ...

DESCRIPTION
       Apply  runs  the  named command on each argument arg in turn.  Normally
       arguments are chosen singly; the optional number n specifies the number
       of arguments to be passed to command.  If n is  zero,  command  is  run
       without  arguments  once for each arg.  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 arg.  If any such sequences occur, n is  ignored,  and
       the  number of arguments passed to command is the maximum value of d in
       command.  The character ‘%' may be changed by the -a option.

EXAMPLES
       apply echo *
              is a time-consuming way to do ‘ls -1'

       apply -2 cmp a1 b1 a2 b2 ...
              compares the ‘a' files to the ‘b' files

       apply -0 date `seq 20`
              runs date 20 times; like ‘for i in `seq 20`; do date; done'

SEE ALSO
       sh(1)

BUGS
       Shell metacharacters in command may have bizarre effects; it is best to
       enclose complicated commands in single quotes ´ ´.
       There is no way to pass a literal ‘%2' if ‘%' is the argument expansion
       character.
