sudo echo tun >> /etc/modules

[boblemur]

hey all,

im trying to write a script to install hamachi, but first i need to add tun to the loaded modules, and when i put sudo at the start of the echo command.. it gets access denied because the echo is run as sudo but the pipe to file isnt.. i was wondering if i could get it to run as root when pipeing

i was thinking i could go

chown <user>
and then chown root after editing but it seems rarther clumsy...

[scragar]

use

sudo su
echo tun >> /etc/modules
exit

to temp gain root privilages, that way your line doesn't need boosting to root, or try:

echo tun >> sudo /etc/modules

It's not the most elegant solution ever, but the quickest one I could think of at this time of night:

echo "tun" | sudo tee -a /etc/modules

Like I said, not the most graceful solution ever, but much much better than chowning it to the user and then back to root.

yeh i would rarther not be logging in as root, as the root account then needs to be enabled for the script to work, i tried the second one ( was my original guess ) and it actualy makes a file sudo and puts tun /etc/modules in it...

[boblemur]

thanks very much, yeh that works perfectly for what i need, ill keep tee in mind... slowly learning all the commands...

thanks again

You're very welcome. I just learned tee myself recently, but its a very useful utility to keep in mind.

tee is very cool.

You can (FYI):

sudo sh -c "echo tun >> /etc/modules"
