Please tell us more about your input file and describe, in English, what you are trying to produce as output.

I don't see how you get uniq -f 3 -c to give you a count of 19 matching lines when you only have one line of input in your sample file?

How is your sample input file ordered (assuming there is more than one line in your input file?

If you only have one value in the 1st field in your input file, why not just print the 1st line of the file and use wc -l to add the line count?

GIT-NAME-REV(1) 						    Git Manual							   GIT-NAME-REV(1)

NAME
git-name-rev - Find symbolic names for given revs SYNOPSIS
git name-rev [--tags] [--refs=<pattern>] ( --all | --stdin | <commit-ish>... ) DESCRIPTION
Finds symbolic names suitable for human digestion for revisions given in any format parsable by git rev-parse. OPTIONS
--tags Do not use branch names, but only tags to name the commits --refs=<pattern> Only use refs whose names match a given shell pattern. The pattern can be one of branch name, tag name or fully qualified ref name. If given multiple times, use refs whose names match any of the given shell patterns. Use --no-refs to clear any previous ref patterns given. --exclude=<pattern> Do not use any ref whose name matches a given shell pattern. The pattern can be one of branch name, tag name or fully qualified ref name. If given multiple times, a ref will be excluded when it matches any of the given patterns. When used together with --refs, a ref will be used as a match only when it matches at least one --refs pattern and does not match any --exclude patterns. Use --no-exclude to clear the list of exclude patterns. --all List all commits reachable from all refs --stdin Transform stdin by substituting all the 40-character SHA-1 hexes (say $hex) with "$hex ($rev_name)". When used with --name-only, substitute with "$rev_name", omitting $hex altogether. Intended for the scripter's use. --name-only Instead of printing both the SHA-1 and the name, print only the name. If given with --tags the usual tag prefix of "tags/" is also omitted from the name, matching the output of git-describe more closely. --no-undefined Die with error code != 0 when a reference is undefined, instead of printing undefined. --always Show uniquely abbreviated commit object as fallback. EXAMPLE
Given a commit, find out where it is relative to the local refs. Say somebody wrote you about that fantastic commit 33db5f4d9027a10e477ccf054b2c1ab94f74c85a. Of course, you look into the commit, but that only tells you what happened, but not the context. Enter git name-rev: % git name-rev 33db5f4d9027a10e477ccf054b2c1ab94f74c85a 33db5f4d9027a10e477ccf054b2c1ab94f74c85a tags/v0.99~940 Now you are wiser, because you know that it happened 940 revisions before v0.99. Another nice thing you can do is: % git log | git name-rev --stdin GIT
