My script in a pipe??? 1

[rogsal]

Hi all!

I've written a script that greps for a string and outputs b lines before and a lines after.
> fblock STRING -b 2 -a 2 FILE

but now I would like to use it in a pipe like this:
> unzip -c enormous_log.gz | fblock STRING -b 2 -y a

How do I do that???

I don't know fblok, perhaps man fblock ?

Oh! Maybe I was a bit confusing in my first post.
fblock is the name of my script which I want to modify so it can be used in a pipe aswell.

The script would need to check if the input file is supplied as an argument. If it is not, then assume that input is piped. The first command in the script that uses stdin must then process the pipe, e.g...
[tt]
if [[ ! $File ]]
then
File=/tmp/file$$
cat > $File #---this is being piped into
fi[/tt]
