apply(1) General Commands Manual apply(1)
apply - Applies a command to a set of arguments
apply [-acharacter] [-number] command argument...
The apply command runs the specified command on each argument in turn.
Identifies the character used instead of the % (percent sign) to designate argument substitution strings. Specifies the number of argu-
ments to be passed to command.
Normally, arguments are chosen individually; the optional number specifies the number of arguments to be passed to command. If number is 0
(zero), command is run without arguments once for each argument.
If you include character sequences of the form %n (where n is a digit from 1 to 9) in command, they are replaced by the nth unused argument
following command when command is executed. If any such sequences occur, number is ignored, and the number of arguments passed to command
is the maximum value of n in command.
You can specify a character other than % (percent sign) to designate argument substitution character strings with the -a option; for exam-
ple, -a@ would indicate that the sequences @1 and @2 were to be replaced by the first and second unused arguments following command.
Shell metacharacters in command may have undesirable effects; it is best to enclose complicated commands in ' ' (single quotes).
There is no way to pass a % (percent sign) followed immediately by any number if % is the argument expansion character.
The following command is similar to ls: apply echo * The following command compares the file a1 to the file b1, a2 to b2, and so on: apply
-2 cmp a1 b1 a2 b2 ... The following command runs who 5 times: apply -0 who 1 2 3 4 5 The following command links all files in the current
directory to the directory /usr/joe: apply 'ln %1 /usr/joe' *
Commands: sh(1), xargs(1)
