AW: check_command $ARGx$ with SPACE characters ?

My experience with spaces in args is that it does not work if you compiled
Nagios with embedded perl. Without embedded perl Nagios calls a shell and
this shell calls the plugin. The shell groups everything between two ' or "
to one argument. With embedded perl Nagios calls the script without a shell
and Nagios does seperate the args between spaces.
For the one script I have wrote that need spaces in arguments I escape
spaces (with %20) and percent-signs (with %25) and decode the string in the
perl script with:
# dieser RE kommt aus uri_unescape() aus dem modul URI::Escape
$argument =~ s/%([0-9A-Fa-f]{2})/chr(hex($1))/eg;
You call your plugin with:
check_command check_fugger!1234!test%20param1%20param2
Hope this helps...
