[Script Shell] How can i check for sudo

[geearf]

Hello,

I am doing a little install script for my work using shell, and I want to test wheter the script was started with or with sudo.
If it was without, and I need it I will put it in front of my command ..

But i cannot find a way to check for sudo ($USER only gives me the user).

Thanks for the tip

#! /bin/sh

ROOT_UID="0"

#Check if run as root
if [ "$UID" -ne "$ROOT_UID" ] ; then
	echo "You must be root to do that!"
	exit 1
fi

Thanks a lot

Thanks it works flawlessly for my needs

Would you also happen to know how can I store 'file /usr/bin/java' in a variable in my script ?


Thanks

You need ` quotes to evaluate an expression.

#! /bin/sh

FILE_JAVA="`file /usr/bin/java`"

echo "$FILE_JAVA"

Oh ok,

thank you very much for your help,

Do you happen to know a good website for learning shell script (so that I won't bother you too much ) ?

[Sam]

Just Google for "bash tutorial" and you'll find a lot of websites...

Here's some:

• Introduction to bash shell scripting, a good start
• AWK, GRP, SED tutorial, useful for parsing command outputs
• Introduction to Bash Programming pt. 1, pt. 2

Ask if you have a question! Happy scripting

Thanks,

I have looked at shell script and stuff like that, but I always found about the same stuff, that is why I asked here in fact

Thanks for your help,
