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_filefi
In Bash how does one determining the length of filename?
bash;rename
You can use ${#VAR} to get the length of a variable $VAR:if [ ${#filename} -eq 5 ]; then   rename_filefi
