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 dth 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 flag option. EXAMPLES The command apply echo * is similar to ls(1); apply -2 cmp a1 b1 a2 b2 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/mcfong` * links all files in the current directory to the directory /usr/mcfong. FILES /usr/ucb/apply SEE ALSO csh(1), ksh(1), sh(1), xargs(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. April, 1990 1
