replacing part of filename

berrance · 04-25-2010, 07:44 AM

I have just re transcoded a bunch of avi's. to tell the new ones from the old ones I put '[xvid]' at the end of all the new avi's. but now I have deleated the old avi's I want to remove the [xvid] part of the file name.

This is what I have so far

Code:

#!/bin/bash
for name in *.avi
do
newname=`echo "$name" | tr -d [xvid]`
echo "$name" "$newname"
mv "$name" "$newname"
done
##########

but that just removes all the leters X, V, I & D from the file name and doesnt actualy remove the string '[xvid]' from the file name.

any point in the wright direction would be helpfull

Thanks Berrance

"[xvid]" in fact means any one of the four characters. Try it without the brackets

Code:

#!/bin/bash
for name in *.xvid
do
    newname=${name%.xvid}
    echo mv "$name" "$newname"
done

The [ & ] are part of the file name. the file names are like

"video [xvid].avi"

I wand the square brackets removing aswell. I want to remove the " [xvid]" from every file name so the new file name is

"video.avi"

I think you'll need to "escape" the brackets---eg \[xvid\]

Generally if you give a script that is not working it always helps to provide what your starting with and
how you want it to look. Are we to assume that the file names may contains spaces as in your example:

Quote:

"video [xvid].avi"

Because your output does not only remove the desired string of "[xvid]" but also the prior space.

Assuming we can ignore the space, the following, which builds on catkin's approach, should work:

Code:

#!/bin/bash
for name in *.avi
do
    newname=${name/\[xvid\]/}
    echo mv "$name" "$newname"
done

No need for a script. There's a command for that:

Code:

rename '[xvid]' '' *.avi

'man rename' for details.

Code:

rename 's/\ [xvid]//' *.avi

Is the way to go.

Thanks for the help guys

Hmm, that looks more like a sed/regex. Looks like you have a different version of 'rename' to me.
The slackware one uses this syntax http://linux.die.net/man/1/rename
