how to change file names to uppercase in a directory
All my files are having names in lower case. I wanted to change these names to upper case. I am using red hat linux version 8. How can i change all the file names to upper case in a directory?

Put this script named "ucf" in /usr/local/bin and, as root, type "chmod a+x ucf".


# uppercase any filenames with lowercase chars
for file in $*
 if [ -f $file ]
  ucfile=`echo $file | tr [:lower:] [:upper:]`
  if [ $file != $ucfile ]
    mv -i $file $ucfile

Then you can change all lowercase filenames in the current directory to uppercase by typing "ucf *"

UPPERCASE to lowercase
Can I please ask how this useful script could be modified to change not only the files of a specific directory but also the files found in its subdirectories? If you could do this I would be very grateful.

Thank you. Phidor

if you have Python and don't mind using an already made script, you can try my script called File Renamer(see my sig)
eg usage

# ls -ltR
-rw-r--r-- 1 root root    0 Jun 16 14:29 file1.Doc
-rw-r--r-- 1 root root    0 Jun 16 14:29 testFile.TXT
drwxr-xr-x 2 root root 4096 Jun 16 14:28 test

-rw-r--r-- 1 root root 0 Jun 16 14:28 FILE.PDF
-rw-r--r-- 1 root root 0 Jun 16 14:28 File.TIff
-rw-r--r-- 1 root root 0 Jun 16 14:28 file.txt

# -d 2 -p ".*" -e "a-z" -l "*"
==>>>>  [ /home/test/testFile.TXT ]==>[ /home/test/images/testfile.txt ]
==>>>>  [ /home/test/images/file1.Doc ]==>[ /home/test/images/file1.doc ]
==>>>>  [ /home/test/images/test/FILE.PDF ]==>[ /home/test/images/test/file.pdf ]
==>>>>  [ /home/test/images/test/File.TIff ]==>[ /home/test/images/test/file.tiff ]

-d option means depth level (set to 2 levels deep, so change as appropriate). remove -l option to commit changes

if you don't have Python, then just use normal GNU find

find /home/test/ -type f -name "*[A-Z]*" -printf "%h:%f\n" | awk 'BEGIN{q="\047";FS=":"}
 newpath = $1"/"tolower($2)
 cmd = "mv "q $1"/"$2 q" "q newpath q

Great one! Tried the latter (ie without Python) and it ran like clockwork - first pop. Thanks so much. It was an academic exercise more than a practical necessity - I wanted to see if it could be done. It can! Thank you for your help. I'll now sit down and nut out the code!

Thanks again for such a prompt response!
