Environment Path Variable Not working properly

Question

I've edited my .bashrc file because of errors like the one below keeps popping every time I open a terminal.

Command 'ls' is available in '/bin/ls'
The command could not be located because '/bin' is not included in the PATH environment variable.

So far I've tried( in my .bashrc file):

export PATH=/bin:/usr/bin:/usr/local/bin:/sbin:/usr/sbin
exportPATH=/usr/bin:/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
export PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"
export PATH=$PATH:/usr/bin

still, I've to enter explicitly one of the above-said commands in the terminal every time I open a new one. I'm using Ubuntu 16.04.

Any help will be appreciated.

ls resides in /bin. But apparently you have messed up your PATH somehow; on a clean Ubuntu install PATH is set in /etc/environment. Can you please edit your question and show us what echo $PATH outputs. — Gunnar Hjalmarsson, Apr 10 '18 at 18:26
The PATH should be set in your ~/.profile, not ~/.bashrc, though that's not the cause of the problem. — wjandrea, Apr 10 '18 at 20:32
@GunnarHjalmarsson when I echo $path, this shows up $PATH:$JAVA_HOME/bin — SevenDante, Apr 11 '18 at 02:55
That's very wrong. Please remove all tweaks of PATH you have made to start with. — Gunnar Hjalmarsson, Apr 11 '18 at 04:09
@GunnarHjalmarsson That tweak was necessary for Hadoop installation which I was following. — SevenDante, Apr 11 '18 at 09:07
In any case you did it wrong. If you want help to correct it, you need to show us exactly what you did. — Gunnar Hjalmarsson, Apr 11 '18 at 13:47

When you are using Bash-Shell you should define the PATH Variables the following way in your .bashrc:

PATH="/bin:/usr/bin/: and other paths:$PATH"

Print the Path env-varibale

printenv PATH

So that we can see what happens.

/bin and /usr/bin are included in the default PATH. There shouldn't be any need to add them again. – wjandrea Apr 10 '18 at 20:33
