Ubuntu – Passing Variable into awk gsub

awkbashcommand linescripts

I have this command
Here 

vovar=OBJECTS
prvar="$(awk '/'"$vovar"'/,/}/ {gsub("$vovar"," "); gsub("}",": %s,"); gsub("{"," ");gsub(",",": %s,");print}' temp1)"

Contents of temp1

ciscoFlashCopyCompletionTrap NOTIFICATION-TYPE
        OBJECTS   
                { 
                ciscoFlashCopyStatus  
                }
        STATUS  current
        DESCRIPTION
                "A ciscoFlashCopyCompletionTrap is sent at the 
                completion of a flash copy operation if such a trap 
                was requested when the operation was initiated.
                "
        ::= { ciscoFlashMIBTraps 1 }

What I want the command to do 

                ciscoFlashCopyStatus  
                : %s: %s,

What it actually does

        OBJECTS   

                ciscoFlashCopyStatus  
                : %s: %s,

How can I change my awk command so that I can get what I want?

Best Answer

You used vovar outside single quotes for the first time, but not the second time:

... awk '/'"$vovar"'/,/}/ {gsub("$vovar"," ") ...

If you'd been consistent:

$ awk '/'"$vovar"'/,/}/ {gsub("'"$vovar"'"," "); gsub("}",": %s,"); gsub("{"," ");gsub(",",": %s,");print}' foo


                ciscoFlashCopyStatus  
                : %s: %s,
