Remove last line from all files of a specific extension

I have several files with same extension .txt in a directory. I want to remove the last line from all .txt files.

What I did is

find . -type f -name '*.txt' -exec sed '$d' {} \;

This prints the desired output from sed to the terminal for every .txt file.

What I want is to modify the respective files.

Solution

  • Try this:--

    sed  -i '$d' *.txt

    "$" is used as a line number and means the last line in the file.

    "d" is usd to delete the respective line(last line in this case).

    "*.txt" is used to select all files whose extension is .txt in the present directory.
