rename files to the same name but with lowercase

[Salvador Reyna]

Hi, I'm trying to convert the files in lowercase.
f.e:./folder/FILe1.tXT
./folder/fiLE2.TXT

I'm trying with "awk", I'm trying with "tr".

Somebody told me ..."with LINUX anything is imposible"..... I'm not sure :-((

Could you help me, please?

[Jean-Luc Oudart]

try this

F1="./folder/FILe1.tXT" # or whatever
NEWNAME=$(echo $F1 | tr '[A-Z]' '[a-z]')
mv $F1 $NEWNAME

Regards
Jean-Luc

if your using a posix style shell:

typeset -l newFileName

filename=ABC
newFileName=$filename

print $filename $newFileName

[curt larson_1]

and with awk

fileName=ABC
print $fileName | awk '{print tolower($0);}'

[Alan Meyer_4]

Be sure to check to see if the new(lowercase) file name does NOT already exist
if [ -f "newfile.txt" ] ;then
... modify name here ...

Hi,

I'm not sure about your question, in any case pls try this:

for FILE in `ls -d *`
do
FILE_CAP=`echo $FILE|awk '{ print tolower ($1) }'`
mv FILE FILE_CAP
done

Saludos

Oooopss..!

The correct sintax must be:
for FILE in `ls -d *`
do
FILE_CAP=`echo $FILE|awk '{ print tolower ($1) }'`
mv $FILE $FILE_CAP
done

rgds again

The tr man page gives you the details:

cd /some_folder/

for MYFILE in $(echo * .[!*]}
do
LOWERCASE=$(echo $MYFILE | tr -s '[:upper:]' '[:lower:]')


if [ -a $LOWERCASE ]
then
echo "\nFile $LOWERCASE already exists, cannot rename $MYFILE\n"
else
mv $MYFILE $LOWERCASE
done


Notice the test for a duplicate just in case you have two separate files such as: File1 and FILE1 which will be duplicates when changed to lowercase.

Well, i'm not sure if i've explained fine my problem.

I have some files in a folder.
File1.txT ,FILe2.Txt,fILe3.TXT

I need that all these files become in lowercase, but not one by one; all in the same time.

Like that: file1.txt,file2.txt,file3.txt

Thanks a lot

Hi again,

All of them at once..! uummmhhh, is relative point of view, pls try my last suggestion, this move file by file in an unique cicle.

Saludos.

Hi Salvador:

You could do something like:

# cd /folder
# perl -e 'for $x (@ARGV) {$y=$x;$y=~s/($x)/\L\1/g;rename $x,$y}' FILe1.tXT fiLE2.TXT

This will rename files of mixed upper and lower case as specified by the argument list, to filenames consisting of only lowercase letters.

Regards!

Salvador,
take this 1-line command that converts your files altogether:

find . -type f|awk '{print $1,tolower($1)}'|xargs -n2 mv 2>/dev/null

Good luck,
Alex

[Alessandro Pilati]

Obiovusly launch the command after you did a "cd " where the files to convert are present.

Regards,
Alex

GREAT !... THANKS A LOT for everybody.

Jose Maria, I didn't see your update. In your third comment I saw the right version.

THANKS & REGARDS
