Question read in variable data from another file - grep
Hello! I think this should be an easy solution. I have a large file with many fields of data. The first field has a unique identifier (a subject number) for every record for a chunk of data. Something like this:
Quote:
1 [Data] [Data] ...
1 [Data] [Data] ...
1 [Data] [Data] ...
1 [Data] [Data] ...
2 [Data] [Data] ...
2 [Data] [Data] ...
2 [Data] [Data] ...
2 [Data] [Data] ...
There were ten experimental conditions (ec), but the ec is identified by only one field in one record for each subject. I already ran a script to create a list of all subject numbers and their corresponding ec. For simplicity's sake (or so I think) I divided up that list by ec, so i now have numerous lists containing all of the subject numbers for each ec. I hope you can picture this.

Lets call my main data file "all.inq" and my lists "[0-9].lst"

I want to grep all the records in all.inq that begin with the numbers listed in 0.lst and put them in a file 0.inq, and then repeat the process for all other lists. This is probably a one liner, but I just don't know much about grep.

Thanks!
Chris
