It can be very tedious to have to type full command to log into a remote machine using the secure shell (ssh) when a remote machine is used often.
Add a custom command to the .bashrc
A simple solution is to add a custom command to the .basrc. Open the .bashrc (which is in the root of home directory) using any plain text editor. E.g.: <source lang='bash'> vi $HOME/.bashrc </source>
Then, using the alias function, define a new function derived from the ssh command and your personal credentials:
<source lang='bash'>
alias lx7="ssh username@scomp1095.wurnet.nl"
alias hpc="ssh username@nfs01.hpcagrogenomics.wur.nl"
</source>
The new function will be available from next login, therefore log out of the active terminal and log back in. From the freshly opened terminal, issuing the following command:
<source lang='bash'>
lx7
</source>
should give you direct access to scomp1095, for instance. If you do this in combination with a passwordless setup, you will not even be prompted for a password.
