Bug + minor improvements

1) Line 86 has a bug

Original:
elif [$ageproc -gt $warning ]

Corrected:
elif [ $ageproc -gt $warning ]

2) Minor improvements I made

a) nbproc

The “comm,args” options should be changed to “comm” only, otherwise the calculated number of processes is always increased by 1.

nbproc=$(ps -A -o comm | grep -w $proc | grep -v $0 | wc -l)

b) Output

The output should always begin with w.g. “CRITICAL: “, “WARNING: ” or “OK: “.
