Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Changing the terminal title to the last shell command

Changing the terminal title to the last shell command

Found another way, more compatible. Tested with xterm, aterm, gnome-terminal and rxvt (where it sets the window title) and guake (where it doesn't - after all, guake does not show the window title).

Alternatives

There are 6 alternatives - vote for the best!

You can set the previous bash command as the terminal title by this command.

Explanation:

-trap assigns a command to execute at a given bash signal.

-in the $BASH_COMMAND you find the last command

-you can set the terminal title with the escape sequence: \e]0;this is the title\007

-to let the echo care about the backslashes give the -e to it

Since trap is a built in bash command you find more informatin in 'man bash'for more

Source: http://www.davidpashley.com/articles/xterm-titles-with-bash.html

if [ "$SHELL" = '/bin/zsh' ]; then case $TERM in rxvt|*term|linux) preexec () { print -Pn "\e]0;$1\a" };; esac; fi
