Unix commands

Francis Ancheta — Mon, 16 Jun 2003 06:43:42 GMT

whenever I login and use a different account other than root I have problems running commands.

Scenario:

I loggin as xxx execute su to get root prev. run Iptables etc ... etc .. it won't work. But if I login in a different virtual screen using root I wont have any problems. ... I am now pissed off ... going from one screen to another. Isnt it that if you su you are suppose to get root prev.

I am a new user of Linux and I am not sure if Linux as environment settings for path like Windows.

Pls. help.

Hi,

Try to use "su -" (without "")

this way you load the complete root enviroment.

Right on the spot ... Thanks. My second question is there an environment equivalent of "Path" in Linux?

I think your looking for the PATH environment variable. You can look its value in this way:

$ echo $PATH

that print the value of the variable; you can also use this:

$ env

that prints the whole environment variables set.

you can edit the PATH variable so (or just any variable):

$ export PATH=

remember that the ':' divides the entries in the PATH variable (I think it's ';' that does this in windows systems, if i'm not going wrong).
so, if you want add a new command search path:

$ export PATH=$PATH:

Hello!

The PATH in linux is the same variable name
as in UNIX systems -> $PATH
