bash - Removing part of a filename for multiple files on Linux

Question

I want to remove test.extra from all of my file names in current directory

for filename in *.fasta;do 

    echo $filename | sed e 's/test.extra//g'

done

but it complains about not founding file.echo is to be sure it list correctly.

Answer 1

First of all use 'sed -e' instead of 'e'

And I would suggest you do it this way in bash

for filename in *.fasta; do 
    [ -f "$filename" ] || continue
    mv "$filename" "${filename//test.extra/}"

done
