not there yet
I'm getting nothing in my .data file.
When I set -x -v, I see that the program is cycling through each FinalReport file just fine, but nothing is getting written. So I'm guessing the problem is with the 'cat'.
(part of the set -x set -v output:
+ for i in './TryingAgain_Files/TryingAgain_FinalReport*.txt'
+ for j in ''\''cat ./SearchPattern13.txt'\'''
+ grep -m 1 cat ./SearchPattern13.txt ./TryingAgain_Files/TryingAgain_FinalReport1095.txt
+ for i in './TryingAgain_Files/TryingAgain_FinalReport*.txt'
+ for j in ''\''cat ./SearchPattern13.txt'\'''
+ grep -m 1 cat ./SearchPattern13.txt ./TryingAgain_Files/TryingAgain_FinalReport1096.txt)
I also have grepped using the SearchPattern13.txt and it does pull out the data (but I stop it because it would take all day).
for i in ./TryingAgain_Files/TryingAgain_FinalReport*.txt
do
for j in 'cat ./SearchPattern13.txt'
do
grep -m 1 $j $i >>650hgdp13.data
done
done

Hi All,
is there a way to extract the line number of an occurrence using grep?
I know that with the -n option it prints out the line number as well.
I would like to assign the line number to a variable.
Thanks,

GREP(1) General Commands Manual GREP(1)
NAME
grep, g - search a file for a pattern
SYNOPSIS
grep [ option ... ] pattern [ file ... ]
g [ option ... ] pattern [ file ... ]
DESCRIPTION
Grep searches the input files (standard input default) for lines that match the pattern, a regular expression as defined in regexp(7) with
the addition of a newline character as an alternative (substitute for |) with lowest precedence. Normally, each line matching the pattern
is `selected', and each selected line is copied to the standard output. The options are
-c Print only a count of matching lines.
-h Do not print file name tags (headers) with output lines.
-e The following argument is taken as a pattern. This option makes it easy to specify patterns that might confuse argument parsing,
such as -n.
-i Ignore alphabetic case distinctions. The implementation folds into lower case all letters in the pattern and input before interpre-
tation. Matched lines are printed in their original form.
-l (ell) Print the names of files with selected lines; don't print the lines.
-L Print the names of files with no selected lines; the converse of -l.
-n Mark each printed line with its line number counted in its file.
-s Produce no output, but return status.
-v Reverse: print lines that do not match the pattern.
-f The pattern argument is the name of a file containing regular expressions one per line.
-b Don't buffer the output: write each output line as soon as it is discovered.
Output lines are tagged by file name when there is more than one input file. (To force this tagging, include /dev/null as a file name
argument.)
Care should be taken when using the shell metacharacters $*[^|()= and newline in pattern; it is safest to enclose the entire expression in
single quotes '...'. An expression starting with '*' will treat the rest of the expression as literal characters.
G invokes grep with -n and forces tagging of output lines by file name. If no files are listed, it searches all files matching
*.C *.b *.c *.h *.m *.cc *.java *.cgi *.pl *.py *.tex *.ms
