Hi

If i enter vi command or clear command i am getting following error
-bash: vim: command not found

This command are working fine in other users.Hope i will get solution.

Most likely your .bash_profile is corrupted.
Since the other accounts are working, you may refer one of the working accounts profile.

Can you try
to see if the path to vim is located in your PATH environment variable? Typing
into bash or another shell will cause bash to search in the directories in PATH for executables to run.

No, that is not "most likely"; it is ONE possibility; please don't jump to conclusions without having any evidence to support them. It is much MORE likely that (since it WAS working), that the OP has manually entered a command to modify their path, or that another shell script has been run that overwrote the PATH variable. Also, you say ".bash_profile"...but don't mention the .profile, or .bashrc, ALL of which may be involved here. Since you have 'certifications', haven't you studied which files get read when a user logs in?

OP, have you recently edited your system profile? Your user profile? (ANY of them?). Logging out/back in is the best first step, since that will reset ALL your environment variables. If it still doesn't work, then you can work around it initally, just by typing
..which will put most things back in your path (like vi, etc.), and let you diagnose the problem more easily.

What I am thinking is when you enter 'vi' how come bash says 'vim not found'?
Something is wrong here.

Perhaps, but on my openSUSE system /usr/bin/vi is a symbolic link to /usr/bin/vim.

That's interesting....
On my Centos 6.5, vim is /usr/bin/vim and vi is purely an alias to vim (ie no /usr/bin/ entry).
iirc, last time I yum installed 'vi', it really does install /usr/bin/vi ie NOT a symlink to vim.

Guess different distros do it differently.

QN: what happens on openSUSE if you specifically(!) install 'vi'; do you get a real one?

yum install vim*

Don't know. If I query the vi package through yast, it tells me that vi is part of the vim-base package, which is already installed. I presume I could install it from source, but then I'd have to remove the symlink.

First of all i would like to say sorry for late response.

export PATH="/bin:/usr/bin:/usr/sbin:/sbin"

The above command resolves my problem.

Thanks a lot guys.

@TB0ne: true but you could use an alias instead, thus giving you both options

Indeed, but I don't use either too much these days. I prefer kdevelop for my hard-core coding, and vim works fine for the random file.

However, back in the day.....
