| ===== Titles (naming windows) ===== | ====== Title Examples ====== |
| |
| Each screen window has a title. The title is visible in the window display (from the ''windows'' command or ''C-a w'') and you can use names as well as numbers to specify windows for many screen commands. | Each screen window has a title. The title is visible in the window display (from the ''[[commands:windows]]'' command or ''[[commands:windows|C-a w]]'') and you can use titles as well as numbers to specify windows for many screen commands. |
| |
| You can set the default title for your windows with the ''shelltitle'' command in your .screenrc. That may be overridden by the ''-t'' option of the ''screen'' command, the title-string escape sequence (''<esc>k//<new-title>//<esc>\''), and the ''title'' command (bound to ''C-a A''). | You can set the default title for your windows with the ''[[commands:shelltitle]]'' command in your .screenrc.

| A common desire is to name one's windows after the programs running in them. A window sitting at a shell prompt might be named "bash", while one running pine from a shell would be named "pine". | A common desire is to name one's windows after the programs running in them.

| alias postcmd 'echo -ne "^[k\!#:0^[\\"' | alias postcmd 'echo -ne "^[k\!#:0^[\\"' |
| | </code> |
| | |
| | On non-Linux systems like (Free)BSD or Solaris you may use the POSIX version with printf: |
| | <code> |
| | alias postcmd 'printf "\033k\!#\033\\"' |
| </code> | </code> |
| |
| <code> | <code> |
| preexec () { | preexec () { |
| echo -ne "\ek${(s: :)1[1]}\e\\" | echo -ne "\ek${1%% *}\e\\" |
| } | } |
| </code> | </code> |
| <code> | <code> |
| export PS1='\[\033k\033\\\]\u@\h:\w\$ ' | export PS1='\[\033k\033\\\]\u@\h:\w\$ ' |
| | </code> |
| | |
| | Please note the use of single quotes. Also, if you want to use it with a bash prompt that spans several lines you have to put it on the last line. For example: |
| | |
| | <code> |
| | export PS1='\[\033k\033\\\]' |
| | export PS1="\n\u@\h:\w\n"$PS1'\$ ' |
| </code> | </code> |

| As a special case, if the //<default-title>// from above ends in a colon, the name of the currently running program will be appended to the default title instead of replacing it. In the above example, with ''shelltitle "$ |bash"'', if you run pine, the title will change from "bash" to "pine", and back to "bash" when you exit pine. If you use ''shelltitle "$ |bash:"'', the title will change from "bash:" to "bash:pine" and then back to "bash:". | As a special case, if the //<default-title>// from above ends in a colon, the name of the currently running program will be appended to the default title instead of replacing it.
