grep related question

[Sujoy Choudhury]

Hi,

I am trying to find a particulat line from a file.
My ksh code as below

KEY=somekey
# I am trying to find the lines in the file which don't start with a comment (#)
# so the lines which starts with the key above should be returned and after that I invoke awk 
# for further processing 

LINE=`grep '^$KEY_somestring' someFile.properties | awk -F= '{print $2}'`

But this doesn't evaluate $KEY so doesn't return any line.
How can I achieve that?

I could figure this out, the solution is:

`grep '^'"$KEY"'_somestring' someFile.txt | awk -F= '{print $2}'`

You don't need to grep and pipe it to awk. This -

awk -F= '/^'"$KEY"'_somestring/ {print $2}' somefile.txt

- should suffice.
