Linux Commands

  1. How to find .bashrc file
    This file is a hidden file inside your home directory 

Do a:

ls -la ~/ | more

There should be a .bashrc on the first page. If not just create it with:

sudo vi ~/.bashrc

and add in the lines you need to add into it.

Permissions of my .bashrc are:

-rw-r--r--  1 discworld discworld  3330 Mar 10 16:03 .bashrc

(chmod 644 .bashrc to make it rw r r).

2. -bash command not found

This issue happens if there is no $PATH variable set. 

In this case, run the following command: 

export PATH=”/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin”

3. Set JAVA_HOME or PATH

We can set JAVA_HOME or PATH either in /etc/environments or in .bashrc file
