hi just a question about variables in scripts im trying to run this command with out using temporary files but im not sure how to do it

Code:

ps -A > ~/.temp
awk '/fbpanel/ { print $0 }'  ~/.temp

that searches for every application running called fbpanel is there a way a can alter it so that it doesn't write to the hardrive ? ive tried this

Code:

app=`ps -A`
awk '/fbpanel/ { print $0 }'  $app

but that doesnt work any ideas how this should be done ?

Looks like you want a pipe:

Code:

ps -A | awk '/fbpanel/ { print $0 }'
