How to convert all directory names to upper case? 1
- Thread starter knsnln
- Start date
Hi Ken,
Be careful - on a case sensitive box, some really weird shtuff may start happening.
Are you talking about altering the directory structure to reflect upper case names, as this could have serious ramifications, to users/applications expecting different target files.
At a guess, and without knowing your target OS, you're looking at at least a 3 part process.
Phase 1 - Backup your target environment securely & adequately. (GOOJFC)
Phase 2 - create a set of uppercase directories, and copy files from source directories therein - check they don't exist already - what should be the exception here?
Phase 3 - rename the files to lower case in each of the directories you've created
Unless you're the sole, or understood to be deemed, owner of the files, never delete, as people will wait for you in the parking lot, especially if you said you did it on purpose
I doubt if any of this helps

I have a script (bleow) that I use to change the case of directory and file names of directory structures on my NT box. As it stands it changes everything to either upper or lower case, as specified on the commandline, but it would not be difficult to amend it to do one thing with directory names and another with files as it currently treats the 2 separately anyway:
#!/usr/contrib/bin/perl
