how to run two commands in sudo

Question

Is there any way how I can run two Db2 commands from a command line   They will be called from a PHP exec command     db2 connect to ttt  note that we need to have the connection live for the second command db2 UPDATE CONTACT SET EMAIL ADDRESS    mytestaccount gmail com    I tried this   sudo -su db2inst1 db2 connect to ttt  db2 UPDATE CONTACT SET EMAIL ADDRESS    mytestaccount gmail com    The first command finishes correctly but the second one fails with the error message SQL1024N  A database connection does not exist   SQLSTATE 08003  Note that I need to run this as php user  The command sudo -u db2inst1 id as php user gives me correct output

sudo can run multiple commands via a shell  for example      sudo -s --  whoami  whoami  root root   Your command would be something like    sudo -u db2inst1 -s --  db2 connect to ttt  db2 UPDATE CONTACT SET EMAIL ADDRESS    mytestaccount gmail com     If your sudo version doesn t work with semicolons with -s  apparently  it doesn t if compiled with certain options   you can use   sudo -- sh -c  whoami  whoami    instead  which basically does the same thing but makes you name the shell explicitly

On the terminal  type     sudo bash   Then write as many commands as you want  Type exit when you done   If you need to automate it  create a script sh file and run it     sudo   script sh

On a slightly-related topic  I wanted to do the same multi-command sudo via SSH but none of the above worked   For example on Ubuntu     ssh host name sudo sh -c  whoami  whoami   sudo  password for ubuntu  root ubuntu   The trick discovered here is to double-quote the command     ssh host name sudo sh -c   whoami  whoami    sudo  password for ubuntu  root root   Other options that also work   ssh host name sudo sh -c    whoami  whoami    ssh host name  sudo sh -c  whoami  whoami     In principle  double-quotes are needed because I think the client shell where SSH is run strips the outermost set of quotes  Mix and match the quotes to your needs  eg  variables need to be passed in   However YMMV with the quotes especially if the remote commands are complex  In that case  a tool like Ansible will make a better choice

For your command you also could refer to the following example  sudo sh -c  whoami  whoami

The -s option didn t work for me  -i did   Here is an example of how I could update the log size from my bash   sudo -u  user  -i -- sh -c  db2 connect to  database name  db2 update db cfg for  database name  using logsecond 20 db2 update db cfg for  database name  using logprimary 20

An alternative using eval so avoiding use of a subshell   sudo -s eval  whoami  whoami    Note  The other answers using sudo -s fail because the quotes are being passed on to bash and run as a single command so need to strip quotes with eval  eval is better explained is this SO answer  Quoting within the commands is easier too     sudo -s eval  whoami  whoami  echo  end    root root end    And if the commands need to stop running if one fails use double-ampersands instead of semi-colons     sudo -s eval  whoami  amp  amp  whoamit  amp  amp  echo  end    root  bin bash  whoamit  command not found

The above answers won t let you quote inside the quotes  This solution will   sudo -su nobody umask 0000    mkdir -p   targetdir    Both the umask command and the mkdir-command runs in with the  nobody  user
