On linux, using rename to rename multiple directories. I want to rename directories starting with higher case characters to lower case and add a special character, let's say _ before the first letter.
For example I want to rename Myfile to _myfile
The best I came up with so far is :
rename -n 'y/[A-Z]/[a-z]' *
But when I add my character to this regular expression I get the following error :
rename -n 'y/[A-Z]/_[a-z]' *
Replacement list is longer than search list at (eval 90) line 1.
How can I add the special character to the regular expression?
Do:
rename -n 's/^([A-Z])/_\L$1/' */
^([A-Z]) matches any uppercase letter at start, and put in captured group 1
In the replacement, we are lowercasing (\L) the captured group 1 with perpending a _
*/ matches only directories
Remove -n for actual renaming action:
rename 's/^([A-Z])/_\L$1/' */
