bipinajith, Azrael:

Thank you both for the replies. I understand very well the examples you have both posted. If we can make things a little more complex, but at the same time simple in regards to automating weekly tasks, that's the goal of mine...

Using the example code:
Code:
#!/bin/bash  for file in /Desktop/Blah/*              # For each file in directory: /Desktop/Blah/ do         grep food1 $file >> food1.txt    # Grep for food1, redirect & append o/p to file: food1.txt         grep food2 $file >> food2.txt    # Grep for food2, redirect & append o/p to file: food2.txt         grep food3 $file >> food3.txt    # Grep for food3, redirect & append o/p to file: food3.txt done

I'll have MULTIPLE (80+) strings to grep and will increase over time.

Adding/Editing the following code, how can I have files created, that are named after the string "grepped".

Code:
#!/bin/bash

for file in /Directory/*txt

do 

     grep -f mystringsfile.txt >> "the string.txt" #This would be an automatically assigned name. I'm guessing a variable would be needed here. How would it be written?

done

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.
