Issue with bashrc file - bash

When I open the .bashrc file using gedit, or vi editor, there's nothing in it. I am on MINT trying to install Hadoop and one of the step requires editing the .bashrc file, to save the environment variable. I remember doing the same on Ubuntu, and there were contents were in it.
Can you help me get them all back? Is it possible to get them all back?
When I do gedit ~/.bashrc it opens to a blank page.
Thanks in advance!

From looking at the MINT forums, it doesn't look like MINT supplies a default .bashrc:

However, .bashrc is an optional file, so you can add whatever you want to it. Check out the bash man pages:
man bash
Also, if you setup a .bashrc file, make sure it is getting called from either .profile or .bash_profile like this:
# if running bash
if [ -n "$BASH_VERSION" ]; then
# include .bashrc if it exists
if [ -f "$HOME/.bashrc" ]; then
. "$HOME/.bashrc"
fi
fi

You should have one in here:: /etc/skel/.bashrc
Try copying it to your home folder:: cp /etc/skel/.bashrc ~/.bashrc

Look for .bashrc.swap files in your home directory by doing so:
ls -Fa ~ | grep '*bashrc*'
I don't know how gedit or other programs name their swap files, but just look what comes up.
If there are no such files, you're out of luck.

Why must I source .bashrc every time I open terminal for aliases to work?

Git was working fine. I have created an alias in Git but the issue is when I tried to reopen the terminal, then I need to run . ~/.bashrc every time in the terminal.
What is the best way I don't need to provide source every time when I reopen the terminal?
What I did?
I am trying to add source of the .bashrc file in this file but it is a read-only file. I am not able to add the source of the .bashrc file in this profile.
open /etc/profile
Added the permission to write in the profile as well, still not able to link the source file.
sudo chmod u+w /etc/profile
Profile:
# System-wide .profile for sh(1)
if [ -x /usr/libexec/path_helper ]; then
eval `/usr/libexec/path_helper -s`
fi
if [ "${BASH-no}" != "no" ]; then
[ -r /etc/bashrc ] && . /etc/bashrc
fi
It looks like your terminal emulator is launching bash as a login shell.
If that's the case, it will read /etc/profile for configuration as well as 1 of the following files, if they exist (listed in order of importance) :
~/.bash_profile
~/.bash_login
~/.profile
It will thus ignore your .bashrc file. A correct fix for your situation would be to either configure your terminal emulator to run bash interactively and non-login, or add the following line to your ~/.bash_profile :
[ -f "$HOME/.bashrc" ] && . "$HOME/.bashrc"
Here is a link to the documentation about which files are loaded depending of the type of shell you are running
As per #Aserre's answer i have followed this step to solve this issue
A typical install of OS won't create a .bash_profile for you. When you want to run functions from your command line, this is a must-have.
Start up Terminal
Type cd ~/ to go to your home folder
Type touch .bash_profile to create your new file.
Edit .bash_profile with your favorite editor (or you can just type open -e .bash_profile to open it in TextEdit.
[ -f "$HOME/.bashrc" ] && source "$HOME/.bashrc" Save it and close it
Restart the terminal, It should work
You should write this line source .profile inside your .zshrc file. This is because default shell is zsh. If u don't want to do this solution than u can go for changing the default shell by typing the following command chsh -s /bin/bash then restart your machine or virtual machine. Then no need for source. I hope this will help :) TAKE CARE
If you are using Linux and you want variables set, to persist.
Follow the below steps.
Be the root user -> sudo su
go to etc folder -> cd /etc
open the file bashrc with the editor of your choice -> vi bashrc
set the variable with export command like here I am setting JAVA_HOME ->
export JAVA_HOME=pathHere
Load the bashrc file with command ->
. bashrc
remember to put the dot/period before bashrc.
now JAVA_HOME should be set permanently.

Update $PATH variable permanently

Apologies if this duplicate but a lot of other threads are years old.
I want to update my $PATH variable permanently so it doesn't reset everytime I quit Terminal. I have seen people suggest to run the following:
gedit ~/.bashrc
But this returns:
-bash: gedit: command not found
I have used Spotlight to search my hard disk for the .bashrc file and can't find it. Can anyone help?
Thanks in advance...
You don't need an editor for that, you can do this using bash's output redirection operation.
For example, to add /foo/bar you current PATH, append (>>) to ~/.bashrc:
echo 'export PATH="$PATH":/foo/bar' >> ~/.bashrc
To view the content to STDOUT too, use tee -a:
echo 'export PATH="$PATH":/foo/bar' | tee -a ~/.bashrc
the . before the file means it's hidden so that's probably why it didn't show, just like if you do ls from your home folder you won't see it but ls -la will
to edit your file I would suggest using vi instead if gedit is not available
vi ~/.bashrc

How to source additional file when launching bash

Bash will source automatic profiles such as .bashrc. --rcfile option can be used to override the automatic script. But I need to source additional personalized file (that's the automatic script plus another file) when launching the bash shell without touching ANY files in $HOME or /etc directory since $HOME directory belongs to application run user. The personalized file must not be located in $HOME directory.
Is this possible?
I tried:
/bin/bash <<EOF
. /a-directory-outside-of-home/vanilla
EOF
but it returned to the current shell.
Okay, so you want to run the user's normal .bashrc, followed by your own script, and you want to trigger this behavior in the way that bash is called, correct?
The call:
/bin/bash --rcfile myscript
First line of myscript:
source $HOME/.bashrc
bash --rcfile <(cat rcfile1; cat rcfile2)
works just fine and requires no modifications anywhere.
Add your stuff as *.sh files in /etc/profile.d -- read /etc/profile and
http://www.gnu.org/software/bash/manual/bashref.html#Bash-Startup-Files
I wouldn't modify the .bashrc file. Instead, I would modify the .bash_profile
file which is located at $HOME.
It is the place from where .bashrc is included.
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/bashrc
fi
A good option for you is to add a .personalized_settings file and include it
just below the above lines like this.
# Adding personalized settings
if [ -f ~/.personalized_settings ]; then
. ~/personalized_settings
fi
This requires that .personalized_settings file is located at $HOME.
I have tested the above in Fedora12.
Edit :
You might need to look for .profile instead of .bash_profile in Ubuntu (and hopefully other Debian based systems). (courtesy #Benjamin W.)
This (link)[https://www.gnu.org/software/bash/manual/bash.html#Bash-Startup-Files] will give you more information on it.
What if you mess around with any of the profile files?
You have a back-up copy of all these files in /etc/skel which you could
use to restore.

Appending bash alias to .bashrc doesn't work

I want to create a alias of my cd command. I have created the .bashrc file and append the command cd ...... to it. (Since the file was newly created, it just has this one line that I added).
After that, only after I typed . ~/.bashrc, can the alias works. If I close the terminal and open it again, I need to retype . ~/.bashrc.
It's really annoying to do this every time. Is there any way to solve this problem?
Thank you so much for help
When you login to linux system, only ~/.profile will be called:
$ cat ~/.profile
# if running bash
if [ -n "$BASH_VERSION" ]; then
# include .bashrc if it exists
if [ -f "$HOME/.bashrc" ]; then
. "$HOME/.bashrc"
fi
fi
You need to source ~/.bashrc inside ~/.profile manaully.
Read this to learn more.
EDIT:
If you're using iTerm2 on mac, it actually start a login shell by default when open tabs.
But you can change it: Preferences > General > Command
If using OS X, append the alias to ~/.bash_profile.
You could also add alias to ~/.bashrc, then add source ~/.bashrc to ~/.bash_profile.
Better yet, put all your aliases in ~/.aliases, and source it in ~/.bash_profile.
By default, OS X first sources /etc/bashrc (which shouldn't be modified unless absolutely necessary), then sources the user's ~/.bash_profile at the start of every interactive session.

My Bash aliases don't work

I'm not sure why but my Bash aliases don't seem to work. Here is my .bashrc file
# v 0.0.1 - 7/03/12
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting
# expanding history to 10000 commands
export HISTSIZE=10000
# don't store repeated commands more than once
export HISCONTROL=ignoredups
# where to look for Java
export JAVA_HOME=/Library/Java/Home
# tomcat server configuration
export CATALINA_HOME=/usr/local/apache-tomcat-6.0.35
# default editor
export EDITOR=vim
if [ -f ~/.bash_aliases ]; then
. ~/.bash_aliases
fi
Here is my .bash_aliases file
# v 0.0.1 - 7/03/12
# aliases for directory traversal
alias ..='cd ../'
alias ...='cd ../../'
alias ....='cd ../../../'
alias gs='git status '
alias ga='git add '
alias gb='git branch '
alias gc='git commit'
alias gd='git diff'
alias go='git checkout '
alias gk='gitk --all&'
alias gx='gitx --all'
alias got='git '
alias get='git '
Add this to the end of your .bashrc:
if [ -f $HOME/.bash_aliases ]
then
. $HOME/.bash_aliases
fi
I had a similar problem recently. The solution appeared to be closing ALL open shells (root and user; I didn't notice that I was running a minimized root shell at the time while editing my user .bashrc and .bash_aliases files). The .bash_aliases file then seemed to get read.
By default
if [ -f ~/.bash_aliases ]; then
. ~/.bash_aliases
fi
These are available in your .bashrc file in ubuntu 18,19
Actually the problem is sourcing the files, therefore source both files by runing the commands below. I faced the same issues and that is how i solved it.
source ~/.bashrc
source ~/.bash_aliases
Bash doesn't look for a file called .bash_aliases; you have to source it explicitly.
Looking around a bit, it appears ~/.bash_aliases is sourced from the default .bashrc on Ubuntu boxes; I don't have access to one to confirm. However, it is not a standard bash configuration file.
I recently installed RVM and changed my terminal profile to "run command as login shell". This disabled .bashrc from loading.
Fix: edit -> profile preferences -> Title and Command -> Run command as a login shell (uncheck)
Find this post for more information, fixed it for me.
https://askubuntu.com/questions/161249/bashrc-not-executed-when-opening-new-terminal
Sometimes forgetting to source the bashrc also creates this problem. So after adding your aliases don't forget to source it.
source ~/.bashrc
You need to include the file. Example code to do so from a default .bashrc file is below:
# Alias definitions.
# You may want to put all your additions into a separate file like
# ~/.bash_aliases, instead of adding them here directly.
# See /usr/share/doc/bash-doc/examples in the bash-doc package.
if [ -f ~/.bash_aliases ]; then
. ~/.bash_aliases
fi
don't forget to
chmod 600 ~/.bash_aliases
on kubuntu 22.04
;)
It may be something simple. Like you are actually running zsh or korn instead of bash. Check your shell. I have done this on installing and testing various flavors. Wasted so much time I now never assume I am on bash anymore.
