Often times when you transfer files from Windows to Linux, they end up with all Capital letters. While generally, this isn't much of a problem, sometimes this includes large directories and Linux will not see "FILENAME.EXE" the same as "filename.exe". The solution is to issue the following perl command to rename everything in a directory from upper to lower case:

perl -le 'rename $_, lc( $_ ) foreach <*>'

This "tip" is available through the random tip son the frontpage.

Just so everyone knows ... I was an NT and UNIX guy back in 1999 (I was just playing around with Linux on a webserver or 2 back then)...I am a Linux guy now! laugh.gif

(Like I said before...I haven't changed that site since 1999).
And now, back on topic:

For anyone who would rather convert upper to lower case with a shell it is (I named it

# lowerit
# convert all file names in the current directory to lower case
# only operates on plain files--does not change the name of directories
# will ask for verification before overwriting an existing file
for x in `ls`
  if [ ! -f $x ]; then
  lc=`echo $x  | tr '[A-Z]' '[a-z]'`
  if [ $lc != $x ]; then
        mv -i $x $lc
# End of lowerit script

The above file needs to be in the directory you want to change files in ... and it won't currently do files that start with a . (like .Abc123Z) won't get converted ... because most . files are setup files and you don't want to change their case. If you do want to also change the case of . files, change the line for x in `ls` to for x in `ls -a`
