You can skip the further processing if the files are "counterparts". To be clear, if the filename contains "-" (or any other check which you think would be safe).
I've written a script to count the total size of SAN storage LUNs, and also display the LUN sizes.
From server to server, the LUNs sizes differ.
What I want to do is count the occurances as they occur and change.
These are the LUN sizes:
49.95
49.95
49.95
49.95
49.95

I need to search and count the occurrences of a pattern in a file. The catch here is it's a pattern and not a word ( not necessarily delimited by spaces). For eg. if ABCD is the pattern I need to search and count, it can come in all flavors like (ABCD, ABCD), XYZ.ABCD=100, XYZ.ABCD>=500,... (6 Replies)

grep
GREP(1) General Commands Manual GREP(1)NAME
grep - search a file for a pattern
SYNOPSIS
grep [ option ... ] pattern [ file ... ]
DESCRIPTION
Grep searches the input files (standard input default) for lines (with newlines excluded) that match the pattern, a regular expression as
defined in regexp(6). 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.
-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.
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 '...'.

Exit status is null if any lines are selected, or non-null when no lines are selected or an error occurs.
