problem with piping one output to another.Would like to avoid the intermediate file creation.The piping does nt work on places where files have been created and goes in an endless loop.
Where is the "endless loop"?
When posting code, please put it inside [code] tags, and format it so that is it easily readable. I.e., put each command on a new line with indentation to display the structure of the script and to make commenting on individual commands easier.
I've reformatted it here:
Why are you using a file? Why not pipe it directly to tr?
If the purpose of the awk code is to remove duplicates, see below for a more efficient way to do it,
Why are you using a file? Why not pipe it directly to sed?
