This was moved here from a thread discussing a completely different topic.

Without showing us the output that was produced, we don't know what happened when you tried running that command. Did it produce any error messages? What is in file1? What is in file2? What output were you trying to produce from those input files?

As with any awk script, if you don't redirect the output when you write text in your awk script and you don't use redirection in the shell when you invoke your awk script, any output produced by the awk script will be written to standard output.

And, you haven't said what operating system and shell you're using. As you will frequently see me say here, if you are running an awk script on a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk or nawk (preferably /usr/xpg4/bin/awk especially if you're not working in the C or POSIX Locale).

i put my post here sir. Sequence extraction
