Can we check weather the user is Admin or Normal user

[Vaphell]

is it all the script does? moving stuff to restricted directories?

deploy.sh:
sudo mv $from $to


$ ./deploy.sh

No it's more than just moving

i have to restart j boss server

service stop jboss

then check for the processes using
ps ax | grep jboss
kill all the other processes except Jboss
then start the jboss again..

then connect to mysql database in the server
then using mysqldump import database from the package

That's what i have to do

[Vaphell]

what about

deploy.sh:
mv
jboss things
mysql things
...


$ sudo deploy.sh

$ sudo deploy.sh

how can a normal user can do that..
i mean if i run the script normally in bash shell($) rather than (#)

does it move the jboss things??

what i want to say is. in server there are alot of users right?? if every one of them runs this script to move a certain package since this script does it automatically where lies the security they may corrupt the system so i want to check weather they are sudo or not if sudo then proceed if not Authentication failure

#!/bin/bash

id=$(/usr/bin/id -u)

if [ $id -ne 0 ] ; then
  echo "You must use sudo to run this script"
  exit 1
fi

# other stuff goes here...
# mv
# jboss things
# mysql things
# ...

echo Done.

$ ./deploy.sh
You must use sudo to run this script
$ sudo ./deploy.sh
Done.

If the user tries to use sudo and fails to authenticate, your script is not called. If sudo succeeds, then they are authenticated. If the user tries to execute the script without using sudo, then they get an error message. Isn't that what you want?

Thank you but how can i kill all the remaining processes except Jboss?? how is that possible normally we will check with

ps ax | grep jboss
and then by using kill -9 and their pid's we will kill them but how can i do this here??

since the pid's are dynamic how can i kill all except jboss?

Can you provide some sample output from ps that shows the processes you want to kill and the process(es) you don't want to kill?

Also, -9 is a bit heavy handed. It would give the processes a chance to shutdown gracefully if a different signal were used. TERM is the default for kill, is it not working?

Sorry i will give the sample of process which i don't want to kill tomorow i don't know why i can't connect to server through ssh...

Why i said kill -9 is i don't know about the TERM signal... Thank you i will try that

in this i don't want to kill last process jboss

Maybe you can check using pgrep or pkill. They can take a regex pattern and the -u option allows you to specify a user.
