Deleted path variable how to return
 

Experimenting with shell variables, accidentally deleted the path variable how could I return to the original path value. What kinds of problems will I have if I don't have a path variable.

Edit /etc/profile

Put in something like
Some distros do not include /usr/sbin or /sbin in the default $PATH, but it's not necessarily a problem to do so.

If you don't have a PATH variable, the shell doesn't know where to look for commands.

Hi,

if you don't have $PATH in your env variable, the shell won't be able to find the exact location of any command you enter at the command prompt.

To get a lost $PATH var, you can simply copy another user's $PATH to your ~/.bash_profile, assuming you use bash shell.

Did you do something like this?

If so then don't worry. PATH should be automatically restored the next time you login.
