Problem with sudo in Redhat 5

ssuhaib · 04-18-2012, 12:10 AM

Hi Gurus,

I login as a user, do "sudo su", change to userid 'root' and add the value in .bash_profile. I exit after this, login as a user, sudo to root, but echo $variable does not show any value although the value of the variable exist in .bash_profile in root home directory (/root).

Any help with is welcome.

Thanks in advance.

Hi,

Did you export the variable or just declare it? If you declare a variable in .bashrc/.bash_profile you should export it if you want to use it in login shells.

Code:

export VARIABLE="value"

Kind regards,

Eric

Thanks Erictra,

I declared the variable in .bashrc and it is working ! Lesson learnt: add vairables for users logging using sudo in .bashrc.

Hello,

Nice! Also remember that if you didn't export the variable (you only mention declaring it), it will no be available in any sub-shells created. If you consider your problem solved then please mark your thread as such.

Kind regards,

Eric
