I'm doing a little script to rename some files. Actually a lot of files.
The problem and the cool thing is, that I actually just need to change the files that have a filename length of 5 characters.
I did a $(filename:0:5)
and look if there is some leftover, but I guess that's dirty and I would appreciate to know the real or scholastic way of doing this.
Something like that:
if [$(filename).length() == 5]; then
reaname_file
fi

You can use
${#VAR}
to get the length of a variable$VAR
