.bashrc is a shell file placed in the user home directory and sourced while you start an interactive shell in Linux terminals, such as local MobaXterm or in Cygwin. This file can be edited or created to customize bash behaviour, for example, define ENV settings, aliases, functions, call scripts, etc.
How to configure local bash terminal bashrc in MobaXterm?
Let us look at configuring the .bashrc file in your local mobaxterm.
Step #1: Open your local bash terminal
- Open your MobaXterm
- From Terminal Menu, “Open New TAB“
- Click Start Local Terminal
- Your terminal window will open
You would get a window something like below with a banner message,
[20XX-XX-XX 10:24.13] ~ [admin.codetryout] >
Step #2: Open or create the file .bashrc
Edit .bashrc file, using the command vim .bashrc
You can customize your settings there.
Step #3: Example customization
Let us enter a simple alias,
[admin.codetryout] > vim .bashrc alias hello="hello codetryout world"
Step #4: Reloading the bashrc changes to the shell
It is required that you have to reload the .bashrc file to make the changes available in your current shell. (Note, the changes will always be available when you open a new terminal/shell).
To reload .bashrc, use any one of the following methods,
Step #5: Testing your new bashrc
[admin.codetryout] > hello hello codetryout world
More example, creating a bashrc edit, adding an alias to MobaXterm local bashrc:
In this example, we will add an alias to .bashrc, named code1. This alias will curl one web page from codetryout.com, lets’s try now:
# Adding a new entry to MobaXterm .bashrc # Alias name: code1 /home/mobaxterm> echo 'alias code1="curl https://code.codetryout.com/ --output code.html"' >> .bashrc
Restart your MobaXterm or use the command: . .bashrc as shown below to reload your bash configurations in effect.
# Reloading the bashrc /home/mobaxterm> . .bashrc
Testing the new alias from mobaxterm bashrc, calling your alias code1
/home/mobaxterm> code1 % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 311 0 311 0 0 2549 0 --:--:-- --:--:-- --:--:-- 2549
Verifying your bashrc changes
/home/mobaxterm> cat code.html <html> <head> <title>Code.CodeTryout.com</title> <body> <h1>code.codetryout.com</h1><br /> This is a demo website for testing sample code experiments and demos at CodeTryout.com.<br /> Please visit <a href="https://codetryout.com/">CodeTryout.com</a> for more information. </body> </html>
Similarly, you may add anything that works on a shell to your bashrc, such as auto-login to a server using SSH, file copy using SCP, etc. Hope this helps
