[Nagiosplug-help] Questions using negate?

[Voon, Ton]

I think there is a problem in spopen which affects negate and other plugins
where external command calls with double quotes do not work correctly.

RIGHT (no spaces in command)
$ negate /usr/bin/grep Network /etc/services
# Network services, Internet style
nntp            119/tcp         usenet          # Network News Transfer
ntp             123/tcp                         # Network Time Protocol

WRONG (spaces lost when passed to spopen - I think it is running a grep
against a file called Time, then /etc/services)
$ negate /usr/bin/grep "Network Time" /etc/services
/etc/services:# Network services, Internet style
/etc/services:nntp            119/tcp         usenet            # Network
News Transfer
/etc/services:ntp               123/tcp                         # Network
Time Protocol

WRONG (same as above)
$ negate /usr/bin/grep 'Network Time' /etc/services
/etc/services:# Network services, Internet style
/etc/services:nntp            119/tcp         usenet            # Network
News Transfer
/etc/services:ntp               123/tcp                         # Network
Time Protocol

WRONG (spopen returns NULL if " found in the command line)
$ negate '/usr/bin/grep "Network Time" /etc/services'
Could not open pipe: /usr/bin/grep "Network Time" /etc/services

RIGHT (spopen doesn't mind ' and the shell has kept the spaces in between)
$ negate "/usr/bin/grep 'Network Time' /etc/services"
ntp             123/tcp                         # Network Time Protocol

I'll look into using cfpopen (http://www.cfengine.org) to see if that will
help, but it will take me ages!
