The bug is NOT the error of the original GNU package, but of the way how it is integrated into the Ubuntu 21.04, because if I download the GNU package itself, compile and try, then it works fine.
In detail what I did: mkdir -p ~/bash cd ~/bash rm -fr bash-* sudo apt-get -y install byacc wget https://ftp.gnu.org/gnu/bash/bash-5.1.tar.gz tar xvzf bash-*.tar.gz rm bash-*.tar.gz cd bash-* time ( ./configure ; make ) env -i PATH="$PWD:$PATH" ./bash --noprofile --norc and here if I do the same cut and paste tests, and drop a command with a terminating line feed character, then this bash binary will simply execute it ... -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to bash in Ubuntu. https://bugs.launchpad.net/bugs/1925823 Title: Ubuntu version of BASH losts or misinterprets the newline character coming from mouse paste Status in bash package in Ubuntu: Confirmed Bug description: Quiete a few experients shows, that bash misinterprets the newline- character coming from mouse paste, while in the same terminals the emacs or vim or alpine and many other character oriented programs interprest correctly. The problem is specific to the situation when we are at a bash prompt of a new version of bash we got in Ubuntu 21.04. As soon as I invoke an ssh session, the interpretation of the newline-caharcter becomes correct, since the remote older bash interprets correctly. >>> Newline bug of first kind: If there is a complete bash command with terminating newline in the cut and paste buffer, and it is pasted into a gnome-terminal, then the command is *not* executed, the newline is ignored by the terminal. >>> Newline bug of second kind: If I prepare a bash command say cp target-directory and I collect into the paste buffer "source-file newline-character" and I drop it IN BETWEEN the prepared "cp" and "target-directory" then the result is wrong: instead of interpreting the newline-character as "push enter" the command is broken into the followint 2 lines: cp source-file target-directory and I get an error message about missing target specification. cp: missing destination file operand after 'source-file' Try 'cp --help' for more information. bash: target-directory: Is a directory I found better to make this original bug descripton more informative.
