Every time when I enter my user in ubuntu I get this error:
Command 'ls' is available in '/bin/ls'
and I solved it by:
export PATH=/usr/bin:/binbut the problem is when I end the session and reenter, the same error appear ..
I'm beginner in using ubuntu OS, also I'm working in an account without sudo access ..

According to the diff output, your problem is definitely inside your ~/.bashrc. You should correct it by editing. (To edit files in your home directory (~), root permissions should not be necessary unless something else is messed up.)
In the first export command, you overwrite the current PATH contents by not including $PATH. To extend the existing list, the command should read:
export PATH="/home/bghanem/python/python27/bin:$PATH"You can also merge both export commands into one.
Moreover, you should use $HOME instead of ~ when setting the PATH variable (thanks @DavidFoerster for the explanation!), so the result is:
export PATH="$HOME/anaconda/bin:$HOME/python/python27/bin:$PATH"Use your favorite editor to edit the file. In your current situation, you might need to invoke it using the full path, e.g. /bin/nano. After that, don’t forget to reload .bashrc using . ~/.bashrc or by opening a new shell.
You have to edit 3 files :
~/.bashrcand~/.profile
You must add your command line in both files, at the end (your command line is export PATH=$PATH:/usr/bin:/bin)
/etc/environment
You must add your command at the end of the file, but without export (in your case, just add PATH=$PATH:/usr/bin:/bin)
Now, to apply your change, you have to reboot your computer, or you can also type these following commands which will apply these changes without reboot :
source ~/.bashrc
source ~/.profileNB : don't forget the $PATH inside your export, PATH isn't empty so you can have some issues if you forget to add it
open ./bashrc in any editor then write at the end of file
PATH="$PATH:/usr/bin:/bin"or you can add as many path appending to it ":path" and then update it by
source ./bashrcI solved it following the answer here: Setting "export PATH=/usr/bin:/bin" permnently
I edited ~/.bashrc file:
pico ~/.bashrcat the end of the file I found these lines:
PATH="/home/common/bin:$PATH"
export PATH=/home/MY_USER/python/python27/bin
export PATH="~/anaconda/bin:$PATH"I added below them:
PATH="/usr/bin:/bin"and I saved it ..
