How to rename multiple files from one extension to another on Linux / Unix?

Question

I have several files that end in ".1", for example:

example.file.ex1.1 example.file.ex2.1 example.file.ex3.1 

Is there a way that I can quickly rename them all without ".1" at the end (for example, example.file.ex1, example.file.ex2, etc.)?

Thanks!

Answer 1

Pure bash solution:

 for curFile in example.file.*.1; do mv -- "$curFile" "${curFile:0:-2}" done 

Answer 2

Yes, try this by renaming :

 rename -n 's/\.1$//' * 

remove -n (idle switch) if your tests are correct.

There are other tools with the same name that may or may not do this, so be careful.

If you run the following command ( linux )

 $ file $(readlink -f $(type -p rename)) 

and you have a result like

 .../rename: Perl script, ASCII text executable 

then this seems to be the right tool =)

If not, make it the default (usually already) in Debian and its derivative, for example Ubuntu :

 $ sudo update-alternatives --set rename /path/to/rename 

---

Last but not least, this tool was originally written by Larry Wall, the father of Perl.

Another bash using parameter extension :

 for curFile in example.file.*.1; do mv "$curFile" "${curFile%.1}" done
