使别名在终端会话中处于活动状态而不使用bashrc或bash_profile或bash_aliases？

Question

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.

Answer 1

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 ssh ing 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.
