APPLY(1) General Commands Manual APPLY(1) NAME apply, pick - repeatedly apply a command; select arguments SYNOPSIS apply [ -ac ] [ -n ] command arg ... pick [ arg ... ] 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 option. Pick writes each argument to the standard error and reads a reply. If the reply is the argument is echoed to the standard output; if the re- ply is pick exits without reading any more arguments; there is no out- put for any other response. If there are no arguments, lines of the standard input are taken instead. EXAMPLES apply echo * Time-consuming way to do apply -2 cmp a1 b1 a2 b2 Compare the `a' files to the `b' files. wc -l `pick *.[ch]` Interactively select `.c' and `.h' files and count the lines in each. apply "wc -l %1" `pick *.[ch]` Same, but use a separate process to count each file.
