Proc::ProcessTable

Please use github or rt.cpan.org to submit bugs and patches.

MAINTENANCE STATUS

This module is maintained by Joachim Bargsten. I have nearly zero knowledge of the implementation within but wanted to rescue the distribution from abandonment and try to get critical bug fixes out. This will need to be a community effort.

The source is in github -

https://github.com/jwbargsten/perl-proc-processtable

Commit bits will be generously granted, send me your github id.

STATUS

This is BETA software; it seems to work, but use at your own risk :)

Currently works on darwin, nonstop-ux, Windows (both native MSWin32 and Cygwin), linux, solaris, aix, hpux, freebsd, irix, dec_osf, bsdi, netbsd, unixware 7.x, SunOS and openbsd. Please see the "README.osname" files for details on individual os implementations. Please see the file PORTING if you are interested in making it work on something else. Please see the file TODO for a list of issues that need to be addressed (and send me patches!).

Please note that the Windows port is derived from Cygwin code and is therefore covered by the Cygwin license (http://cygwin.com/licensing.html).

Multithread support is now available for Solaris; please see README.solaris for info. It may work under other OS's as well; please let me know if it does.

Comments, bug reports, patches and especially ports are greatly appreciated. If you want to submit a patch, please use standard context-diff format; if you're submitting a port, a tarball of the new files is great.

DESCRIPTION

This module is a first crack at providing a consistent interface to Unix (and maybe other multitasking OS's) process table information. The impetus for this came about with my frustration at having to parse the output of various systems' ps commands to check whether specific processes were running on different boxes at a larged mixed Unix site. The output format of ps was different on each OS, and sometimes changed with each new release of an OS. Also, running a ps subprocess from within a perl or shell script and parsing the output was not a very efficient or aesthetic way to do things.

With this module, you can do things like this:

# kill memory pigs
use Proc::ProcessTable;

my $t = Proc::ProcessTable->new;
foreach my $p ( @{$t->table} ) {
    if( $p->pctmem > 95 ){
        $p->kill(9);
    }
}

There is another short example in the file "example.pl" in the distribution. For a more elaborate example (in German), see http://www.linux-magazin.de/ausgabe.1999.02/Proc/proc.html. If you can't read German, try my other module, WWW::Babelfish!</shameless plug>

There are also two contributed modules: a module called Proc::Killall contributed by Aaron Sherman to kill all processes whose command-lines match a given pattern, and a module called Proc::Killfam by Stephen Lidie to kill a list of processes and their children. These modules are installed along with Proc::ProcessTable. Pod documentation is included in both of them.

INSTALLATION

This module needs the File::Find and Storable modules in order to work. File::Find is generally included with perl distributions; Storable is available from CPAN.

After unpacking the tar file, do:

    perl Makefile.PL
    make
    make test
    make install

There is embedded POD documentation in ProcessTable.pm and Process/Process.pm.
