Yes, /usr/local/bin/chcase.

That's what I thought, but it likes it, without it , rejection. It's odd.

[root@localhost root]# chown root:root /usr/local/bin/chcase
[root@localhost root]# ls -la /usr/local/bin/chcase
-rw-r--r-- 1 root root 3921 Sep 24 15:29
/usr/local/bin/chcase
This is not working. I suspect something is overriding
the command and changing it back.It seems that
it does not matter if I issue the above command , or go
to the permissions window for /usr/local/bin/chcase and
insert x in the right places. Something removes them.
But,
[root@localhost root]# cd /root/Desktop/mont (where the .JPG files are
stored)
[root@localhost mont]# chcase
Setuid/gid script is writable by world.
[root@localhost mont]# ls -la /usr/local/bin/chcase
-rwsrwsrw- 1 root root 3921 Sep 24 15:29
/usr/local/bin/chcase*
This is Wierd,
So lets try again, fresh terminal,
[root@localhost root]# chmod 755 chcase
chmod: failed to get attributes of `chcase': No such file or directory
you don't think maybe it ought to be chmod 755 /usr/local/bin/chcase,
so lets try,
[root@localhost root]# chmod 755 /usr/local/bin/chcase
[root@localhost root]#
that's better,
[root@localhost mont]# chcase
chcase 1.2
USAGE:
chcase [-erdouqnl] [-s <dir>] [-x '<perl exp>'] '<mask>'
-e : Print EXAMPLES - very helpful!
-r : Rename recursively
-d : Also rename subdirectories
-o : Overwrite if file exists
-u : Change to upper case (default is lower)
-q : Quiet mode (no output)
-n : No escape characters (for bold output)
-l : Rename & follow symbolic links (default is not to)
-s <dir> : Specify starting directory
-x '<perl exp>' : Perl expression to operate on filename
usually s/// or tr/// (yes you need the quotes)
case of filename not changed when this option used
you can supply multiple expressions
'<mask>' : Mask to rename (quotes are nice to have here)
not case sensitive, you can use multiple masks
-or- just supply the filename(s) on the command line
[root@localhost mont]#
now that's a lot better.
So which is the correct option to rename in lower case ?
I will try , since I am in the directory that contains the .JPG files,
[root@localhost mont]# chcase -e
chcase 1.2
EXAMPLES:
> chcase My.DOC *.JPG FileName.txt
=> these specific files are changed to lower case
> chcase -rd '*'
=> all files and sub dirs to lower case, start in current dir, recurse
> chcase -s pics '*.jpg' '*.gif'
=> rename .jpg and .gif files in pics dir to lower case
> chcase -rous /tmp/junk 'a??b*.txt'
=> starting from /tmp/junk and recursing, change files matching this
mask to all upper case, overwrite if file exists
> chcase -x 's/99dec/jan2000/' -x 's/ /_/g' '*.doc'
=> renames *.doc files replacing 99dec with jan2000,
and replacing all spaces with underscores
> chcase -x 'tr/a-zA-Z0-9.//cd' -x 's/jpg/jpg/i' '*'
=> removes all non-alphanumeric characters except for '.' and
changes the pattern "jpg" to lower case if it isn't already
> chcase -r
=> displays directory structure
So I'm guessing but,
[root@localhost mont]# chcase -rd
.
[root@localhost mont]#
[root@localhost mont]#
[root@localhost mont]# It seemed to like that, but it didn't work,
> -s pics '*.jpg'

well it's certainly not simple. I need time to play around with it.
Needless to say nothing above actually converted the files to lowe case.
