Need to change filenames in a particular directory from lowercase to UPPERCASE

Duke_Lukem · #1 (**permalink**) 01-04-2008

Hi,

I need a shell script which changes a bunch of files in a particular directory from lowercase to UPPERCASE.

I am not very familiar with shell scripts so a detailed explanation would be greatly appreciated!!!!

Thanks ini advance!

Give this a shot. This will change ALL filenames in the current directory from lower to UPPER.

Code:

cd /path/to/your/files

for file in * ; do mv $file `echo $file | sed 's/\(.*\)/\U\1/'` ; done

Code:

for file in *
do 
    echo $file|tr '[a-z]' '[A-Z]'
done

I leave it to you to rename the files.

If you have zsh:

Code:

autoload -U zmv
zmv '(*)' '${(u)1}'

With ksh (not sure if ksh88 supports it):

Code:

typeset -u t;for f in *;do t="$f";mv "$f" "$t";done

Hi cassj,

I tried the above code you generously provided, however the only thing that the code does is add a "U" to the beginning of each filename in the the directory.

Is there some syntax that is slightly incorrect here???
Thanks for your help!

Hi radoulov,

Your ksh script worked a treat - thanks a bunch!!

Hmmm.... I just copied and pasted the code I posted and it worked fine for me. I'm using bash. I'm glad radoulov's code worked for you.
