NAME
Sys::Proctitle - modify proctitle on Linux
SYNOPSIS
use Sys::Proctitle qw/:all/;
setproctitle( "my new title" );
setproctitle( qw/my new title/ );
$s=getproctitle;
or
{
# set proctitle while in block
my $proctitle=Sys::Proctitle->new( 'my new title' );
...
}DESCRIPTION
Sys::Proctitle provides an interface for setting the process title shown by ps, top or similar tools on Linux. Why do we need this? One could simply change $0 to achieve the same result. Well, first setting $0 did not work with 5.8.0. Further, setting $0 won't work with mod_perl.
Procedural Interface
- setproctitle( arg1, arg2, ... argN )
-
all arguments are joined with
\0. The resulting string is set as process title. - getproctitle()
-
returns the current process title. On Linux the space useable as process title consists of the original space for argv the process was executed with plus the space of the original environment. This function returns the current content of this buffer.
The length of the returned string is the maximum process title length.
Object Interface
- new( arg1, arg2, ... argN )
-
the current process title is saved. Then the arguments are passed to
setproctitle. - DESTROY()
-
restores the saved process title.
EXPORT
None by default.
On demand setproctitle and getproctitle are exported.
The :all Exporter tag exports setproctitle and getproctitle.
