Recursive grep

Hello,

First time post - I have no formal unix training and could use some help with this. I have a list of strings in File1 that I want to use to do a recursive search (grep) under a specific directory.


Here is an example of the string I need to search:

/directory/dire ctory/directory/dire ctory/filename

I'm trying to illustrate that the string is a full directory path of a file where some of the directories have spaces in their names.

I then have the following script:

for h in `cat file1`; do grep -rl "$h" /../../../../../ >> /../../file2 ; done

So, I'm trying to say for each string in file1, do a recursive grep in the specified directory and print the results to file2.

The problem (I think) I'm running into is the format of the string I'm searching, the cat I'm doing is treating the spaces as escapes which throws the grep off. I've tried putting the string in single and double quotes but it's still not working.

Sorry for the lack of technical terminology - I hope I was clear enough.

If anyone can offer any help on making it work with what I have or a simpler alternative to what I have, it would be a great help.

Thanks - upstate boy

cp(1)							      General Commands Manual							     cp(1)

Name
       cp - copy file data

Syntax
       cp [ -f ] [ -i ] [ -p ] file1 file2

       cp [ -f ] [ -i ] [ -p ] [ -r ] file... directory

       cp [ -f ] [ -i ] [ -p ] [ -r ] directory... directory

Description
       The command copies file1 onto file2.  The mode and owner of file2 are preserved if it already existed; the mode of file1 is used otherwise.
       Note that the command will not copy a file onto itself.

       In the second form, one or more files are copied into the directory with their original file names.

       In the third form, one or more source directories are copied into the destination directory with their original file names.

Options
       -f   Forces existing destination pathnames to be removed before copying, without prompting for confirmation.  The -i option is  ignored	if
	    the -f option is specified.

       -i   Prompts  user  with  the name of file whenever the copy will cause an old file to be overwritten. A yes answer will cause to continue.
	    Any other answer will prevent it from overwriting the file.

       -p   Preserves (duplicates) in the copies the modification time, access time, file mode, user ID, and group ID as allowed  by  the  permis-
	    sions of the source files, ignoring the present umask.

       -r   Copies  directories.  Entire directory trees, including their subtrees and the individual files they contain, are copied to the speci-
	    fied destination directory. The directory, its subtrees, and the individual files retain their original names. For	example,  to  copy
	    the directory including all of its subtrees and files, into the directory enter the following command:
	    cp -r reports news
