When bash is not working, then you have a problem.
You way want install bash by different ways.

It sounds like your $PATH is not set.
What are the contents of ~/.bashrc and ~/.bash_profile ?

Alternatively, what is the output of $PATH:

Code:

$ $PATH
bash: /usr/local/bin:/usr/bin:/bin:/usr/games:/usr/lib64/kde4/libexe

If the application is installed to your home directory, it is likely not in your path. You should be able to run them using the complete /path/to/application.

Looks like the system utility directories are missing from your PATH. At a minimum it should include /bin, /usr/bin and /usr/local/bin

On my CentOS installation, PATH includes

Code:

/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:

Until that's fixed, you'll need to supply the absolute path to a utility, e.g.

Code:

/bin/vi ~/.bashrc

...or, temporarily,

Code:

PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:$PATH

should allow ls and vi to work again.

Is it possible that the PATH got corrupted in this login instance? Have you tried rebooting?

Hi All,

Thank for your suggestions. I figured it out. I have added two files under /etc/profile.d/

java.sh & maven.sh and these file got messed up. So my friend helped me in it.

He performed this command - $export PATH=$PATH:/usr/bin/ Then, he moved those files (java.sh & maven.sh) form /etc/profile.d to /var/tmp

Now everything works fine as expected. Once again thanks for your help & support.

Thanks & Regards,
