how to change extensions for many files in other directory path
 

Hi, I've got to learn how to change the extensions for many files in the working directory using the following command
but I want to know how to do the same job with specifying a path to another directory that contains the files I want to modify, in other words, I don't want to navigate to each directory using "cd" to run that command.

Hope someone here have an answer, I've been googling a lot about this but couldn't find it.

Thanks you in advance.

Perhaps something like this:

that worked like charm, but not with the first "/", I did it like this:

Thank you very much for your help

bigrigdriver's example uses an absolute path ie tells the cmd where to start in terms of the entire disk partition ie starting from the root dir.
Yours is a relative path ie it'll only work if that path exists in your current dir.

mv *.txt *.doc will expand to:

mv a.txt b.txt *.doc

*.doc will be interpreted as a directory and fail.

Another ways to do this (my personal favorite):

ls /path/to/dir/*.ext1 | sed -e "s/^\(.*\).ext1/\1.ext1 \1.ext2/g" | xargs -n 2 mv -f

But alas, someone decided that was too much to bear, so in comes:

rename .ext1 .ext2 /path/to/dir/*.ext1

Hehe, hope this helps.

Thank you,
You can also use rename instead of mv by the same method.

My name here is "alMubarmij" .. Why you changed it to "Mubarak" ?!
