Proc::ProcessTable, version 0.40
Please note that I've moved development of this package to
sourceforge.net. Please address all comments/bugs/patches to:
http://sourceforge.net/projects/proc-ptable/
STATUS
======
This is BETA software; it seems to work, but use at your own risk :)
Currently works on darwin, nonstop-ux, Cygwin on Windows, linux,
solaris, aix, hpux, freebsd, irix, dec_osf, bsdi, netbsd, unixware 7.x
and SunOS. 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 Cygwin/windows port requires the Cygwin
environment to work (available from http://cygwin.com/), and that the
code for the 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;
$t = new Proc::ProcessTable;
foreach $p ( @{$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>.
<shameless plug> 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.
