How can I do to sort (descending order or ascending order) the file based on the contents inside each header?

Hi,... substitute the new line char for a escape char.... after that, substitute the combination escape char + new record char.... after that sort... after that go back to where we start... substitute the escape char for a new line....

That is:
Code:
tr '\n' '#' < INPUT_FILE | awk '{ aux=$0; gsub("#>","\n>",aux); print aux; }' | sort | tr '#' '\n'

Hi,

After I trying this code:
Code:
tr '\n' '#' < INPUT_FILE | awk '{ aux=$0; gsub("#>","\n>",aux); print aux; }' | sort | tr '#' '\n'

I get the output like:
>aaa
MMMMASDSADSAMDASDSADSADSADSADSADDDDDDDDDDDDDDASDOIIEOUWIOEUQWIOEWQOEUWQIOEUWQIEOWQE

The output result is a bit different with what I'm desired. Do you know what is the main reason?
Thanks a lot Smilie
