Hello
I'm in trouble with a simple shell script that give
erroneous value when running ...
If I run commands interactively everything runs well
> ps ax | grep slapd | grep -v grep | wc -l
1
If I run in the following shell script :
#!/bin/sh
SD=0
SD=`ps -ax | grep slapd | grep -v grep | wc -l`
echo $SD
the result is 3 !!!
Any info welcome !
