Looking for the proper way to bring a string into the stdin. I have a string that I would like to grep and awk. Each have to be run separately, not piped together. So far, the only way I could figure out how is to echo the string and pipe it:

term::size::perl
Perl(3pm) User Contributed Perl Documentation Perl(3pm) NAME
Term::Size::Perl - Perl extension for retrieving terminal size (Perl version) SYNOPSIS
use Term::Size::Perl; ($columns, $rows) = Term::Size::Perl::chars *STDOUT{IO}; ($x, $y) = Term::Size::Perl::pixels; DESCRIPTION
Yet another implementation of "Term::Size". Now in pure Perl, with the exception of a C probe run on build time. FUNCTIONS chars ($columns, $rows) = chars($h); $columns = chars($h); "chars" returns the terminal size in units of characters corresponding to the given filehandle $h. If the argument is omitted, *STDIN{IO} is used. In scalar context, it returns the terminal width. pixels ($x, $y) = pixels($h); $x = pixels($h); "pixels" returns the terminal size in units of pixels corresponding to the given filehandle $h. If the argument is omitted, *STDIN{IO} is used. In scalar context, it returns the terminal width. Many systems with character-only terminals will return "(0, 0)". SEE ALSO
It all began with Term::Size by Tim Goodwin. You may want to have a look at: Term::Size Term::Size::Unix Term::Size::Win32 Term::Size::ReadKey It would be helpful if you send me the Params.pm generated by the probe at build time. Please reports bugs via CPAN RT, http://rt.cpan.org/NoAuth/Bugs.html?Dist=Term-Size-Perl BUGS
I am having some hard time to make tests run correctly under the "cpan" script. Some Unix systems do not seem to provide a working tty inside automatic installers. I think it needs some skip tests, but I am yet not sure what should be the portable tests for this. Update: This distribution uses new tests to skip if filehandle is not a tty. It was noticed that "Test::Harness" and "prove", for instance, provide a non-tty STDOUT to the test script and automatic installers could provide a non-tty STDIN. So the former tests were basically wrong. I am improving my understanding of the involved issues and I hope to soon fix the tests for all of Term::Size modules. AUTHOR
