Perl Interpreter

"Perl" is an acronym for "Practical Extraction and Report Language." It is a language for processing text, derived from C, sed, awk, and the Unix shells.

Unix, Linux and Mac: Perl is installed by default on all UNIX, Linux and Macintosh systems.

Windows: Active Perl is available for installation in workstations running Microsoft Windows.

Vendor Information
Perl is Open Source software. It can be downloaded from several sites.

There are numerous Perl user lists and news groups:

    Running Perl
    Users creating perl scripts must be careful in specifying the location of the perl interpreter. In Skew, the interpreter is in "/usr/local/bin/perl". Thus, the first line in the script should be #!/usr/local/bin/perl. Scripts in Skew can be executed by typing "perl scriptname" at the command line or by making the script executable (with the chmod command).

    In other Unix hosts, the location of the perl command interpreter can be determined with the whereis command (whereis perl).

    Examples and Solution
    See Kellogg's online program samples.

    There are sample scripts in CPAN and other archives.

    Manuals Available at Research Support
    For documentation in Skew, check the Perl manual pages (man perl). The installation of Active Perl in a workstation will include documentation in HTML format.
