executing system command from within perl script

[manishrathi]

I want to execute a command line command from within perl script.

By that I mean, if I want to execute "perl insideScript.pl" from within"perl outsideScript.pl". How can I do this ?

Do I just add a line of code "perl insideScript.pl" in the "perl outsideScript.pl", wherever I want to run insideScript or do I need to do anything else ?

Thanks

Use the system-command for this, e.g. my $result = system("perl insideScript.pl");.

Alternatively, you could use backticks (`` or qx//) (e.g. my @result = `perl insideScript.pl`;).

As you see, the difference is on how to handle the output and result of your inner script.

HTH, Rata

I suspect you are attempting to use perl as if it was a shell. UNIX shells inspect commands and decide if they are keywords, aliases, built-ins, functions or external programs (or other exotics). This is quite unusual for a programming language, but convienient for a command-line driven shell. Perl, like most programming languages, does not work in this way.

See system, which is based upon the function of the same name in C (although it is smarter). You can also use back-ticks `` as you would in a shell, or qx.
