How to replace # with character in fasta file after header and space

Question

[Neel]

Hi, I want to replace for multiple file # with character/name of the strain/gene name and i want to remove this line from my file -1 # ID=1_2660;partial=00;start_type=ATG;rbs_motif=AGGA;rbs_spacer=5bp;gc_cont=0.687.

The first step is pretty straightforward: sed "/^>/s/#.*$//g" will delete everything after the first # till the end of the line. This will leave you with such a file

This file, you could reshape accordingly with paste -d \| - - - , however I suspect that the example you provided is somehow mangled, because that MexT in a separate line is no valid Fasta. Plus, where does that PA_PAO1 in the desired output come from?

Thank you so much for your time, Actually i want to add strain name also so that i can track later which gene from which strain.
