Thank you both for the replies. I don't think I'm executing your suggestions correctly, I've tried all 3.

Jim,

I'm definately confused by which files go where when I read yours.

assume:
strings.txt = file with strings I want find
results.txt = output file of search results

I am trying:

find /directory/I/want to/search/ -type f | \
while read results.txt
do
grep -f strings.txt $results.txt
done

When I use this, I get:

read: `results.txt': not a valid identifier

era,

I didn't get any errors with your suggestions but strings I'm searching are still being broken up, meaning the spaces or '/' in the strings are being handled as breaks turning 1 string into several small strings that are each getting searched.

A better example of what I was originally trying to do is:

for h in `cat strings.txt`; do grep -rl "$h" /directory/path/I want/to/search/ >> /home/directory/results.txt ; done

using /../../ in my original post was not the best choice on my part when they are the equivalent of back ticks.

I'm going to continue to fiddle with all the suggestions, if any further guidance can be offered it would be a great help.

Thanks upstate boy

When finding a string in files within a directory, one can use this: grep -r "searchstring" dir/subdir/ > listofoccurrences.txt For brevity sake one can enter the intended directory and use this: grep -r "searchstring" . > listofoccurrences.txt which as I found out leads to an endless loop,...

x2sys_merge

X2SYS_MERGE(1gmt)					       Generic Mapping Tools						 X2SYS_MERGE(1gmt)

NAME

       x2sys_merge - Merge an updated COEs tables

SYNOPSIS

       x2sys_merge -Amain_COElist.d -Mnew_COElist.d

DESCRIPTION

       x2sys_merge  will read two crossovers data base and output the contents of the main one updated with the COEs in the second one. The second
       file should only contain updated COEs relatively to the first one.  That is, it MUST NOT contain any new  two  tracks  intersections  (This
       point  is  NOT checked in the code). This program is useful when, for any good reason like file editing NAV correction or whatever, one had
       to recompute only the COEs between the edited files and the rest of the database.

       -A     Specify the file main_COElist.d with the main crossover error data base.

       -M     Specify the file new_COElist.d with the newly computed crossover error data base.

OPTIONS

       No space between the option flag and the associated arguments.

       EXAMPLES
	      To update the main COE_data.txt with the new COEs estimations saved in the smaller COE_fresh.txt, try

	      x2sys_merge -ACOE_data.txt -MCOE_fresh.txt > COE_updated.txt
