Add to your bash profile to minimize carpal tunnel syndrome. Doesn't work with user@hostname but appending "-l user" works fine if needed. Works for ping as well.. complete -W "$(echo `cat ~/.ssh/known_hosts | cut -f 1 -d ' ' | sed -e s/,.*//g | uniq | grep -v "\["`;)" ping

Sample Output

$ssh myserver.<tab>

Enable tab completion for known SSH hosts

If you have a lot of hosts in /etc/hosts this would be very useful. Anyone have any more concise examples?

What Others Think

Doesn't work very well on a modern SSH system where the known_hosts file is hashed. It's a good idea though.

ajt · 723 weeks and 1 day ago

@ajt to turn off hostname hashing, you may change either /etc/ssh/ssh_config or ~/.ssh/config and change HashKnownHosts from yes to no. . The approach shown here is cute, but there is a package in Debian/Ubuntu named 'bash-completion' which extends bash's command completion to help you tab-complete program *arguments*, like ssh hostnames or image/gimp file names when running gimp.

bwoodacre · 723 weeks ago

@bwoodacre however the know_hosts file is hashed for a reason - to prevent "bad" scripts from hoping from server to server...

ajt · 723 weeks ago

@ajt I read your comment as you saying there was no way to turn off that hashing and so mentioned how to do it. Obviously there is a reason that hashing is turned on by default for added security, but it is still an option that may be turned off by the user if they so choose.

Cuando decimos mesías yo pienso acerca de presencia. Tenemos maestros espirituales maravillosos que están enseñando al apuntar al Espíritu de muchas maneras diferentes, en idiomas diferentes y tradiciones diferentes. Eckhart Tolle habla acerca de la presencia y el momento presente. Jesús lo llama el instante santo, entrar al instante santo y la presencia del amor de Dios. Por lo tanto, el Mesías es la presencia, es la presencia Yo Soy que se encuentra dentro nuestro. un curso de milagros
