Thanks for reply The ctrl + C really helps. But I still can't manage to remove lines with digits though.
I'd tired [[:digit:]] with sed like this:
sed '/[[:digit:]]/d' input.txt > output.txt and still get empty output.
You say the output is empty. What do you mean? Do you mean that nothing is written to the terminal (which is what you should expect), or do you mean that the command:
after you run your sed command completes doesn't print anything but a shell prompt for the next command?

HISTORY
The GNU shtool subst command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 2001 for GNU shtool. It was prompted
by the need to have a uniform and convenient patching frontend to sed(1) operations in the OpenPKG package specifications.
SEE ALSO shtool(1), sed(1).
