Ubuntu – Set bash as default shell with option to enter into fish

bashcommand linefish

I've seen a few questions as to how to enter into bash while fish is the default shell. I actually want to do the opposite. I currently have fish as my default shell, but would like to return to bash as my default. However, I do not want to uninstall fish and would like the option to enter into a shell session with fish at my discretion. Any advice on how to do this?

You could change your default shell to bash by typing in the following line:

chsh -s /bin/bash

You will probably need to log out and log back in for the settings to take effect.

Then if you wanted to run fish, it would just be the command fish at a bash prompt.

Ubuntu – Run executable file on terminal

Your script should look like:

#!/bin/bash

passwd

Save it in a file, let say password.sh or simple password, then make it executable using next commands in terminal:

cd /path/to/password.sh  #or cd /path/to/password
chmod +x password.sh     #or chmod +x password

To run it from terminal, just use the following command:

./password.sh            #or ./password

/path/to/password.sh     #or /path/to/password

To run it only using:

password.sh              #or password

you must to add the path of the script to the PATH. See How to add a directory to the PATH? in this sense.
