Shell Programming and Scripting

hi to all

i wrote a script to cut a word from the file....that works only if the word is fixed field.

example..
sed -n '1p'|awk '{ print $2 }'|cut -d '(' -f2|sed 's/(//'|sed 's/)//'|sed 's/"//g' filename

i know that word is starting with "app" then "(" ----> ex: app("xxxx").

it works when the value came in second field.. if the value is in 5or 6 filed it will fail. but, i need to capture the value where ever it is and the value is not fixed. if it is fixed i can cut the value.. but it is not fixed.

any ideas....

thanks

Please post an example of the input and desired output.

thanks Zaxxon--

i don't have any example.

but, they use this word in post validation script.
my part is just to cut the value from the script.

thanks
