Remove the specific filename extension in a filename in the directory using sed

Question

How can I remove a specific filename extension in the filename in a directory using sed. Like for example I have a files in a directory,

file1.txt
file2.txt
file3.cpp

Then I want to remove the filename extension of a file with .txt extension, so the result is,

file1
file2
file3.cpp

Thanks!

You can use rename:

rename 's/\.txt$//' *

Saying so would remove the .txt extension from matching files.

And if you really want to use sed, this should work:

    for file in *.txt ; do mv $file `echo $file | sed 's/\(.*\)\.txt/\1/'` ; done
