IPC::Filter - filter data through an external process
use IPC::Filter qw(filter); $compressed_data = filter($data, "bzip2");
The filter function provided by this module passes data through an external command, thus providing filtering in non-pipeline situations.
filter
The SHELL_COMMAND, or the PROGRAM with ARGS if more arguments are supplied, is executed as a separate process. (The arguments other than DATA are ultimately passed to exec; see "exec" in perlfunc(1) for explanation of the choice between the two forms.) The DATA (which must be either a simple string or a reference to a string) is supplied to the process on its standard input, and the process's standard output is captured and returned (as a simple string).
exec
If the process exits with a non-zero exit code or on a signal, the function will die. In the case of a non-zero exit code, the die message will duplicate the process's standard error output; in any other case, the error output is discarded.
