The format of the file would be the determining factor here. A simple cut statement may be all you need. Let us know the format so we can give you the best advice.
I guess I should explain whats happening, the old teach a man to fish thing.
The cut binary can be used to cut text out of a file or stream, you specify your delimter with -d, in this case you can use @, and you specify which field to cut with -f.
So say for instance it was 1@2@3@4@5-6-7-8,
- cut -d@ -f1 would give you just the number one.
- cut -d- -f1 would give you just the number 5
- cut -d@ -f4 would give you the number 4
- cut -d- -f4 would give you the number 8
Cut by default will look for tabs as the delimter if you do not specify it with the -d option.
