How to change your shell to
bash and create .bash_profile
Here is a way that users can change their terminal to bash:
chsh -s
/bin/bash
Then you have to enter your user password and open a new terminal
window to see the changes.
How-to create a bash_profile:
Start up Terminal
Type "cd ~/"
to go to your home folder
Type "touch
.bash_profile" to create your new file.
Edit .bash_profile with nano, pico, or TextWrangler.
Type "source
~/.bash_profile" to reload .bash_profile and update any
functions you add.
New from chapter 6:
Write a script: the goal is to create and run the script on
page 89 to list the directory contents.
- First you will need to create a scripts directory
- Next edit your path to include that directory
- Now write the script and save it to your scripts directory as
dir.sh
- Check that the file has execute permissions
- Finally test it on some directories
Create an alias: this will allow you to use a shortcut for
long commands - see page 99
- Create an alias to get to your sandbox directory from the
terminal
- Test it in the terminal
- Once you are satisfied it works add it to your .bash_profile
- Open a new shell and test it again.
