This question is an offshoot of my question on whether there's anything wrong with having aliases on a production server.
So I tried creating a shell script with some aliases
#!/bin/sh
echo "creating aliases..."
alias f='clear;cd ..;ls;pwd'
alias ff='clear;cd ../..;ls;pwd'
Did a chmod +x al.sh, and ran the script ./al.sh, but although the "creating aliases..." statement got printed, none of the aliases worked, because they were obviously active only until the script ran.
So is there a way I can run a script containing the aliases I want, which will remain active as long as the terminal session is active? The basic idea being, not to cause problems for colleagues who use the same server.
For cases when you want to store functions and aliases just for your session, I find it quite useful to have a file with them and sourcing it when I login the server.
So just place it somewhere like:
~/nav_alias_file.sh
And then just after sshing the server type:
source ~/nav_alias_file.sh
Note by the way that, as Sundeep expressed in comments, you do not need the shebang in that file.
