Translating lowercase file names to uppercase.

Kernel 2.6.21.5, Slackware 12.0

Hi:
As a result of having mixed files from different filesystems, I have, in directory foo/, files with filenames in uppercase and files with filenames in lowercase. If I want to convert them to all uppercase how do I do it? Consider this will be later recorded into optical discs. Regards.

Something along these lines (untested)?

Code:

#! /bin/bash

# Configure script environment
export PATH=/usr/bin:/bin
set -o nounset
unalias -a

# Rename files
while IFS= read -r -d '' file
do
    file_upper=$( echo -n "$file" | /usr/bin/tr '[:upper:]' '[:lower:]' )
    echo mv "$file" "$file_upper" 
done < <(find foo -type f -print0)

If it is creating the mv commands you want, remove the echo.

In bash version 4 and later parameter expansion can be used to uppercase a value using var=${var^^}

it looks like homework BUT with 655 posts - i dought it
lower2CAP.sh

Code:

#!/bin/sh
for i in *; do mv "$i" "$(echo $i | tr '[a-z]' '[A-Z]')"; done

I am with catkin for bash 4:

Code:

for x in *;do mv "$x" "${x^^}";done

Or if you have access to rename:

Code:

rename -n 's/(.*)/\U$1/' *

Remove -n to make it happen

Thank you guys, but I've just reconsidered and have seen the problem is unsolvable. Many of the files are of the type
foo.html
foo_files/
If I rename any of the files in foo_files, the HTML page will lack something. Infact, foo.html contains the names of all files in foo_files/. Renaming any of them, means to edit foo.html and change the name there too. Sorry for the inconvenience.

Well that would be a fairly simple sed, but the choice is yours.
