You can run commands from perl using system and backticks. If that's not what you want, what command line shell do you use? (And that's not a Perl question this way.) For example, passing STDOUT of Perl program as an argument to another program looks like this in a POSIX shell: `./c-program "$(perl -e "whatever")"`. _{Edit: corrected a typo.}	[reply] [d/l]

Thank you for your reply. I am using bash shell and "$(perl -e 'print "\x44\x84\xaa\xbb";')" works for me. I do not know perl. Passing numbers to c(executable) as command line args was not working as they are treated as characters. A lot of manipulation was needed to achieve what I needed. I know that python has the required commands. just wondered about perl.	[reply]

Since your Perl one-liner seems to indicate that you work on some flavor of Unix, you could simply redirect the output toward your C program: `perl -e 'print "AAAA"."BBBB"."\x44\x84\n";' > test.c` Or, if you just want to append the output to an existing C program file: `perl -e 'print "AAAA"."BBBB"."\x44\x84\n";' >> test.c` Update: from your new message on Aug 24, 2013 at 17:53 UTC, it looks like I completely misunderstood your requirement. Sorry about that and forget the above.	[reply] [d/l] [select]
