RudiC gave you code that meets all of your stated requirements except that you don't like it. In what way does sort fail to meet your needs?

When we see statements like this after a seemingly good solution is proposed, it often means that the submitter is working on a homework assignment and is not allowed to use the tools proposed. Is this a homework assignment?

Are there other requirements that you haven't stated? If there are multiple lines for a given key in the first file, do you really want a copy of every line with that value in the second file duplicated in your new file for each occurrence of that value in the first file?

Is it important that your program run very slowly for medium sized files and run at a snail's pace for large files?

Is it important that your output file maintain the (possibly unsorted) order of lines in the 1st file and for all copies of lines from the 2nd file?

What OS are you using?

The people who read your posts and try to help you find solutions for your problems are volunteers. We are not on your payroll. This problem may be urgent for you, but you can't expect volunteers to ignore other things that they might want to do to satisfy your personal requirements. There are special forums that can be used for "Urgent" requests. In the regular forums requests that need to be responded to urgently are inappropriate. Is this another indication that you have a homework assignment that is due soon and you haven't figured out how to do it yet?

NAME
git-merge-index - Run a merge for files needing merging SYNOPSIS
git merge-index [-o] [-q] <merge-program> (-a | [--] <file>*) DESCRIPTION
This looks up the <file>(s) in the index and, if there are any merge entries, passes the SHA1 hash for those files as arguments 1, 2, 3 (empty argument if no file), and <file> as argument 4. File modes for the three files are passed as arguments 5, 6 and 7. OPTIONS
-- Do not interpret any more arguments as options. -a Run merge against all files in the index that need merging. -o Instead of stopping at the first failed merge, do all of them in one shot - continue with merging even when previous merges returned errors, and only return the error code after all the merges. -q Do not complain about a failed merge program (a merge program failure usually indicates conflicts during the merge). This is for porcelains which might want to emit custom messages. If git merge-index is called with multiple <file>s (or -a) then it processes them in turn only stopping if merge returns a non-zero exit code. Typically this is run with a script calling git's imitation of the merge command from the RCS package. A sample script called git merge-one-file is included in the distribution. ALERT ALERT ALERT! The git "merge object order" is different from the RCS merge program merge object order. In the above ordering, the original is first. But the argument order to the 3-way merge program merge is to have the original in the middle. Don't ask me why. Examples: torvalds@ppc970:~/merge-test> git merge-index cat MM This is MM from the original tree. # original This is modified MM in the branch A. # merge1 This is modified MM in the branch B. # merge2 This is modified MM in the branch B. # current contents or torvalds@ppc970:~/merge-test> git merge-index cat AA MM cat: : No such file or directory This is added AA in the branch A. This is added AA in the branch B. This is added AA in the branch B. fatal: merge program failed where the latter example shows how git merge-index will stop trying to merge once anything has returned an error (i.e., cat returned an error for the AA file, because it didn't exist in the original, and thus git merge-index didn't even try to merge the MM thing).
