Full Discussion: Using AWK in IF evaluation in KSH
Top Forums Shell Programming and Scripting Using AWK in IF evaluation in KSH Post 302427210 by sniper57 on Friday 4th of June 2010 08:02:40 AM

OK I have an input file (e.g. imput.txt) which looks something like :-

Code:
Server 1  |  Group 1  |   34586   |   Alive
Server 2  |  Group 1  |   92876   |   Alive
Server 1  |  Group 2  |   87321   |   Alive
Server 2  |  Group 2  |   18763   |   Alive


Then I do :-

Code:
while read line
do
   if [[ `awk -F \| '{gsub(/[[:space:]]*/,"",$4); print $4 }'` != "Alive" ]]; then
       print "Server :" `awk -F\| '{print $1}'` " is " `awk -F\| '{print $4}'`
   fi
done < input.txt

Now this doesn't work in that even though all servers are "Alive", the code still enters the if statement.

Thanks for your help.
