Platform-Specific

If you're new to Perl, you should start with perlintro, which is a general intro for beginners and provides some background to help you navigate the rest of Perl's extensive documentation. For ease of access, the Perl manual has been split up into several sections.

The manpages listed above are installed in the /usr/perl5/man/ directory.

Extensive additional documentation for Perl modules is available. This additional documentation is in the /usr/perl5/man directory. Some of this additional documentation is distributed standard with Perl, but you'll also find documentation for any customer-installed third-party modules there.

You can view Perl's documentation with man(1) by including /usr/perl5/man in the MANPATH environment variable. Notice that running catman(1M) on the Perl manual pages is not supported. For other Solaris-specific details, see the NOTES section below.

You can also use the supplied /usr/perl5/bin/perldoc script to view Perl information.

If something strange has gone wrong with your program and you're not sure where you should look for help, try the -w switch first. It will often point out exactly where the trouble is.

Perl is a language optimized for scanning arbitrary text files, extracting information from those text files, and printing reports based on that information. It's also a good language for many system management tasks. The language is intended to be practical (easy to use, efficient, complete) rather than beautiful (tiny, elegant, minimal).

Perl combines (in the author's opinion, anyway) some of the best features of C, sed, awk, and sh, so people familiar with those languages should have little difficulty with it. (Language historians will also note some vestiges of csh, Pascal, and even BASIC–PLUS.) Expression syntax corresponds closely to C expression syntax. Unlike most Unix utilities, Perl does not arbitrarily limit the size of your data -if you've got the memory, Perl can slurp in your whole file as a single string. Recursion is of unlimited depth. And the tables used by hashes (sometimes called "associative arrays") grow as necessary to prevent degraded performance. Perl can use sophisticated pattern matching techniques to scan large amounts of data quickly. Although optimized for scanning text, Perl can also deal with binary data, and can make dbm files look like hashes. Setuid Perl scripts are safer than C programs through a dataflow tracing mechanism that prevents many stupid security holes.

If you have a problem that would ordinarily use sed or awk or sh, but it exceeds their capabilities or must run a little faster, and you don't want to write the silly thing in C, then Perl may be for you. There are also translators to turn your sed and awk scripts into Perl scripts.

But wait, there's more...

Begun in 1993 (see perlhist), Perl version 5 is nearly a complete rewrite that provides the following additional benefits:

Okay, that's definitely enough hype.

Environment Variables

The Perl shipped with Solaris is installed under /usr/perl5 rather than the default /usr/local location. This is so that it can coexist with a customer-installed Perl in the default /usr/local location.

Any additional modules that you choose to install will be placed in the /usr/perl5/site_perl/5.8.4 directory. The /usr/perl5/vendor_perl directory is reserved for SMI-provided modules.

Notice that the Perl utility scripts such as perldoc and perlbug are in the /usr/perl5/bin directory, so if you wish to use them you need to include /usr/perl5/bin in your PATH environment variable.

See also the perlrun mapage.

Diagnostics

The `use warnings' pragma (and the -w switch) produce some lovely diagnostics.

See perldiag for explanations of all Perl's diagnostics. The `use diagnostics' pragma automatically turns Perl's normally terse warnings and errors into these longer forms.

Compilation errors will tell you the line number of the error, with an indication of the next token or token type that was to be examined. (In a script passed to Perl via -e switches, each -e is counted as one line.)

Setuid scripts have additional constraints that can produce error messages such as "Insecure dependency". See perlsec.

Did we mention that you should definitely consider using the -w switch?

Notes

Perl 5.8.4 has been built to be largefile-aware and to use 64–bit integers, although the interpreter itself is a 32–bit application (LP32). To view detailed configuration information, use perl –V and perlbug –dv.

If you wish to build and install add-on modules from CPAN using gcc, you can do so using the /usr/perl5/5.8.4/bin/perlgcc script – see perlgcc(1) for details.

If you wish to build and install your own version of Perl, you should NOT remove the 5.8.4 version of perl under /usr/perl5, as it is required by several system utilities. The Perl package names are as follows:

SUNWperl584core    Perl 5.8.4 (Core files)
SUNWperl584usr     Perl 5.8.4 (Non-core files)
SUNWperl584man     Perl 5.8.4 (Manual pages)

Solaris 10 also ships with the 5.6.1 version of Perl that was included in Solaris 9. If you are upgrading your system and wish to continue to use Perl 5.6.1 as the default Perl version you should refer to the perlsolaris manpage for details of how to do this. Note that you should upgrade your installation to use Perl 5.8.4 as soon as is practicable, as Perl 5.6.1 may be removed in a future release.

The Perl motto is "There's more than one way to do it." Divining how many more is left as an exercise to the reader.

The three principal virtues of a programmer are Laziness, Impatience, and Hubris. See the Camel Book for why.

Bugs

The -w switch is not mandatory.

Perl is at the mercy of your machine's definitions of various operations such as type casting, atof(), and floating-point output with sprintf().

If your stdio requires a seek or eof between reads and writes on a particular stream, so does Perl. (This doesn't apply to sysread() and syswrite().)

While none of the built-in data types have any arbitrary size limits (apart from memory size), there are still a few arbitrary limits: a given variable name may not be longer than 251 characters. Line numbers displayed by diagnostics are internally stored as short integers, so they are limited to a maximum of 65535 (higher numbers usually being affected by wraparound).

You may mail your bug reports (be sure to include full configuration information as output by the myconfig program in the perl source tree, or by `perl –V') to perlbug@perl.org . If you've succeeded in compiling perl, the perlbug script in the utils/ subdirectory can be used to help mail in a bug report.

Perl actually stands for Pathologically Eclectic Rubbish Lister, but don't tell anyone I said that.
