I have been writing several bash scripts, and I have found that while writing them that extra copies of the files have been created which seem to be identical in contents to the normal files, except their extensions are
.save, what are these files, why do I need them, and can I delete them as they are just clogging everything up? They also seem to have the same permission levels set on them as the files that they seem to be copies of.
I am using
nano as my editor.
