NAME

apply - apply a command to a set of arguments  

SYNOPSIS

[-a c ] [-file ... ] command argument ...  

DESCRIPTION

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:

-file ...
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.
