Bash Scipting (New); Run multiple greps > multiple files
Hi everyone,

I'm new to the forums, as you can probably tell... I'm also pretty new to scripting and writing any type of code.

I needed to know exactly how I can grep for multiple strings, in files located in one directory, but I need each string to output to a separate file.

So I'd imagine I'd make a separate text file with each string that I want to grep. ex:
Code:
food1
food2
food3

.

Then i would use a loop function to grep all files in directory /Desktop/Blah/*, and output to a file named "the string i grepped for".

I would greatly appreciate guidance on this, as loops confuse the hell outa me and i'm not sure what "x" means in the following:

Code:
for x in 'cat /Desktop/Blah/*'; grep 'point to strings file' ..........

Where would $x go? Any guidance is helpful. Thanks everyone....

basename

basename(1)							   User Commands						       basename(1)

NAME

       basename, dirname - deliver portions of path names

SYNOPSIS

       /usr/bin/basename string [suffix]

       /usr/xpg4/bin/basename string [suffix]

       dirname string

DESCRIPTION

       The  basename  utility deletes any prefix ending in / and the suffix (if present in string) from string, and prints the result on the stan-
       dard output. It is normally used inside substitution marks (``) within shell procedures.

   /usr/bin
       The suffix is a pattern defined on the expr(1) manual page.

   /usr/xpg4/bin
       The suffix is a string with no special significance attached to	any of the characters it contains.

       The dirname utility delivers all but the last level of the path name in string.

EXAMPLES

       Example 1 Setting environment variables

       The following example, invoked with the argument /home/sms/personal/mail sets the environment variable NAME to the file named mail and  the
       environment variable MYMAILPATH to the string  /home/sms/personal:

	 example% NAME=`basename $HOME/personal/mail`
	 example% MYMAILPATH=`dirname $HOME/personal/mail`

       Example 2 Compiling a file and moving the output

       This  shell  procedure,	invoked  with  the argument /usr/src/bin/cat.c, compiles the named file and moves the output to cat in the current
       directory:

	 example% cc $1
	 example% mv a.out `basename $1 .c`

ENVIRONMENT VARIABLES

       See environ(5) for descriptions of the following environment variables that affect  the execution of basename and  dirname:  LANG,  LC_ALL,
       LC_CTYPE, LC_MESSAGES, and NLSPATH.

EXIT STATUS

       The following exit values are returned:

       0     Successful completion.

       >0    An error occurred.
