bash_profile打不开怎么办，用nano .bash_profile打开
I’ve spent years curating a collection of Mac bash aliases and shortcuts to make my life easier. My full .bash_profile is below, feel free to take whatever you find useful and put it to good use.
A (VERY) QUICK PRIMER ON .BASH_PROFILE FOR MAC USERS
There is a hidden file in your Mac’s user directory named .bash_profile. This file is loaded before Terminal loads your shell environment and contains all the startup configuration and preferences for your command line interface. Within it you can change your terminal promt, change the colors of text, add aliases to functions you use all the time, and so much more.
This file is often called a ‘dot file’ because the ‘.’ at the beginning of it’s name makes it invisible in the Mac Finder. You can view all invisible files in the Terminal by typing ls -al in any directory.
HOW TO EDIT YOUR .BASH_PROFILE
For the newly initiated, here’s how you can edit the .bash_profile on your Mac.
Step 1: Fire up Terminal.app
Step 2: Type nano .bash_profile – This command will open the .bash_profile document (or create it if it doesn’t already exist) in the easiest to use text editor in Terminal – Nano.
Step 3: Now you can make a simple change to the file. Paste these lines of code to change your Terminal prompt.
export PS1="___________________ | \w @ \h (\u) \n| => "
export PS2="| => "
Step 4: Now save your changes by typing ctrl +o Hit return to save. Then exit Nano by typing ctrl+x
Step 5: Now we need to *activate your changes. Type source .bash_profile and watch your prompt change.
MY .BASH_PROFILE
I have been compiling my own set of aliases and configurations for years in which time I have borrowed copiously from others who have made their aliases available online. I can claim credit for very little of what follows. I recently became aware ofalias.sh, a site making sharing BASH aliases easy. Check it out.
Update: Due to popular demand, my bash profile is now available as a Gist for your forking pleasure.
Without further ado, here is my .bash_profile:
