Name
       apply - apply a command to a set of arguments

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

Description
       The program 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 percent sign (%) character can be changed
       by the -a option.

Examples
       The following command line is similar to
       apply echo *
       The next example compares the specified a files to the specified b files:
       apply -2 cmp a1 b1 a2 b2 ...
       The following example run the command 5 times and links all files in the current directory to the directory
       apply 'ln %1 /usr/joe' *

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

       You cannot pass a literal, '%2', if the percent sign (%) is the argument expansion character.

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.

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.

FILES

     /bin/sh  default shell

BUGS

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