I dont understand how this would work. It looks to me like list would be the file name of my list file, and name would just read in each record in the file (??? I dont know if that is the right interpretation). Then, the grep command looks for lines in the data file that start with the subject numbers in the list file. However, If I print to >> $name.out, then I am going to have a new file for every subject... which would not be good. I want to group by experimental condition.

If I am interpreting this correctly, I would be able to to this and just define the output files name to explicly be the ec number, if I read from my individual lists that are already grouped by condition.

Is there a way to read in column $1 from the list file (which is the ec) and have that govern the name of the .out, and then read the second column of the list file (the subject number) into the grep search pattern pattern?

So the grep line would be something like this, i think:
Code:
grep '^$2' all.inq >> $1.out

I just dont know how to read in the master list file so that it would work.

zgrep

ZGREP(1)                                                      General Commands Manual                                                     ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep  options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
