problem with if -z string
someone please help me out here.
i am not a newbie. i just haven't posted on this board in years. i'm talking at least two and a half years. My last user name was TRUEST. i couldn't log into this name because i forgot my password and my aol email address has long been deleted.
anyway, i'm trying run this command to tell me if what is stored in a variable contains a number or not.
if [ -z $string ]
is that correct?
the actual script is this:
#!/bin/sh
result="`ps -ef | grep -v grep | grep loader | awk '{print $2}'`"
if [ "$result" -eq "0" ]
then
sleep 3
/apps/scripts/restart_feed.sh loader
echo "News_Loader Was Restarted On `date`"
echo " "
fi
the line with result. i'm trying to see if the variable result contains a number or an empty space. i'm running this on a Linux box. i know this stuff but i haven't scripted in so long i have forgotten a lot of things
