Hello does anyone know a command I can use to do a bulk rename of muiltiple files that contain different exentions. Basically I want to take:

12343434.sdflk

and rename 12343434

The fille names vary but the extension is 5 digits long. All i want to do is take a the files in the directory and rename them without the 5 digit exstension. This is driving me nuts Help!

In DOS or Windows, the following would do the trick:
ren *.* *.
I would bet that the Linux command is similar.

Linux Shell script to rename files

#!/bin/bash
# To remove blank space
if [ $# -eq 0 ];
then
 echo "Syntax: $(basename $0) file-name [command]"
 exit 1
fi
FILES=$1
CMD=$2
for i in $FILES
do
# remove all blanks and store them OUT
OUT=$(echo $i | sed 's/  *//g')
if [ "$CMD" == "" ];
then
#just show file
echo $OUT
else
#else execute command such as mv or cp or rm
[ "$i" != "$OUT" ] && $($CMD  "$i"  "$OUT")
fi
done

Go to the directory and run the following

files=$(ls)

for file in $files
do
     mv $file ${file%.*}
done

At Steve, this script only removes blank spaces. The files do not contain any blank spaces:

I just want to rename:

apple.12345

to

apple

The script you pasted does not work.

I get the following error:

mv: `438DF44DB7' and `438DF44DB7' are the same file

You probably had a file without any extension.  In that case this would happen.  These commands work for files with this kind of extension, which is the assumption.

Did you receive only one error message?  Are the rest of files converted?

Try this.  This would take care of files that don't have any extension
files=$(ls)

for file in $files
do
     if [[ $file != ${file.*}
     then
         mv  -f $file ${file%.*}
     fi
done

Open in new window
