source ~ bashrc Explained
Any program that obeys the same logic (like all base utils, such as grep(1) or ping(1)) can be used as condition, see examples. The script takes one character as an argument and displays whether the character is small/big alphabet, number, or a special character. Also be aware that you can have multiple elif statements but only one else statement in an if construct and it must be closed with a fi. You can use an elif (else-if) statement whenever you want to test more than one expression (condition) at the same time.
Conditionals
- If you ever mess up your .bashrc and reboot YOU MAY NOT BE ABLE TO LOGIN!
- There is no .bashrc in /etc/ (there is a bash.bashrc, however).
- You could direct .bash_profile to just source .bashrc, but if something happens to your .bash_profile, then it will be unclear why your .bashrc is again not working.
- Adding this function lets you type “up 3” to move up three directory levels.
The most commonly used source command with the bashrc script file is while declaring the aliases. The aliases are used for the creation of customized commands. Here, we will show the usage of the “source ~/.bashrc” file by creating an alias in Linux. In Linux, the “source ~/.bashrc” command is used to update or refresh the changes made in the bashrc file to be applicable in shells permanently. This blog explains the “source ~/.bashrc” command by demonstrating different examples. For the reader’s understanding, the link to the detailed usage of the source command and the bashrc file script is also shared.

- In this chapter of bash beginner series, you’ll learn about using if-else, nested if else and case statements in bash scripts.
- Personally, whenever I install Linux anew, I add some aliases finding an appropriate place in .bashrcE.g.
Contrast .bash_profile and .profile which are only run at the start of a new login shell. (bash -l) You choose whether a command goes in .bashrc vs .bash_profile depending on whether you want it to run once or for every interactive shell start. The appearance of the command prompt can be customized to display useful information. For example, execute this command display the username (“\u”), hostname (“\h”), and current working directory (“\W”). In newer versions of Git for Windows, Bash is started with –login which causes Bash to not read .bashrc directly. I want to customise the shell in the same way I can under Linux (e.g. set up aliases like ll for ls -l), but I can’t seem to find .bashrc or equivalent configuration bashc files.
I think the question here is how to find .bashrc file on Windows. Just notepad ~/.bashrc from the git bash shell and save your file.That should be all. This will generate a new bashrc file with the default values. From my understanding of this issue, Git for Windows should do this automatically. There are numerous test conditions that you can use with if statements. Test conditions varies if you are working with numbers, strings, or files.
