number of me - script problem



Hejsa,
  På solaris og AIX bruger jeg flg. lille kode-stump:

#!/bin/bash

NUM_OF_ME=$(ps -ef | grep num_of_me.sh |wc -l )
echo $NUM_OF_ME

if [[ $NUM_OF_ME -gt 1 ]] ; then echo already running ; exit ; fi

[...]


Men under linux er NUM_OF_ME lig 3, selvom der ikke kører andre kopier
af scriptet.
Hvad sker der lige og hvad kan det bedst løses, så det virker ens på
alle unix-platforme ?

Hilsen
Martin
