I have files with name of the form "NAME-xxxxxx.tedx" and I want to remove the "-xxxxxx" part. The x are all digits.
The regex "\-[0-9]{1,6}" matches the substring, but I have no idea how to remove it from the filename.
Any idea how I can do that in the shell?
If you have the perl version of the rename command installed, you could try:
rename 's/-[0-9]+//' *.tedx
Demo:
[me@home]$ ls
hello-123.tedx world-23456.tedx
[me@home]$ rename 's/-[0-9]+//' *.tedx
[me@home]$ ls
hello.tedx world.tedx
This command is smart enough to not rename files if it means overwriting an existing file:
[me@home]$ ls
hello-123.tedx world-123.tedx world-23456.tedx
[me@home]$ rename 's/-[0-9]+//' *.tedx
world-23456.tedx not renamed: world.tedx already exists
[me@home]$ ls
hello.tedx world-23456.tedx world.tedx
echo NAME-12345.tedx | sed "s/-[0-9]*//g"
will give NAME.tedx. So you can use a loop and move the files using mv command:
for file in *.tedx; do
newfile=$(echo "$file" | sed "s/-[0-9]*//g")
mv "$file" $newfile
done
If you want to use just the shell
shopt -s extglob
for f in *-+([0-9]]).tedx; do
newname=${f%-*}.tedx # strip off the dash and all following chars
[[ -f $newname ]] || mv "$f" "$newname"
done
