How to make command line shortcuts

[rosslaird]

I ssh into a remote server several times each day. I dutifully type in:

ssh myusername@remotehostname:/dir/I'm/looking/for.

This takes forever. Is there a way to shortcut the typing (I already have password-less login configured, so at least that is quicker). Even just a shortcut for the username and hostname would be good. I do use the up arrow to find the previous entry, but often I've done dozens of other commands since I logged into the server, so sometimes the up arrow repeating takes longer than the typing...

I'd like to be able to type: ssh web

Thanks.

You could add a line such as

export WEB=myusername@remotehostname:/dir/I'm/looking/for

In your ~/.bashrc file. (If you edit this in a console window, you must open a new one for changes to take effect.)

Then you can do

ssh $WEB

Bash has a number of ways to reduce typing...

First of all is aliases. Add something like the following to your ~/.bashrc file:
alias sshtox='ssh user@remote:/dir/to/be/in'
Logout and back in (or type 'source ~/.bashrc' at a shell) and you can now perform the command by just typing 'sshtox'.

Another handy trick is to use Ctrl+r. This does a search through your recently typed commands. Hit Ctrl+r and start typing a part of the command you remember typing and bash will find it for you. Hit Ctrl+r again to scroll through the choices.

Alternatively, DJ_Max's suggestion is just as valid.

In general, Retrix's suggestion of using a bash alias is a good one. For the specific case of typing "ssh web" to get to your webserver, check out the documentation for ssh_config. You can modify your ssh config file so that it applies specific options when you ask to ssh to "web".

Thanks very much for all the tips and suggestions. This is going to make things much easier.
