unix - How to execute commands on different CLI from shell script? -

i have connect different cli , execute few commands , exit. sudo $signmcli connects cli. below script doesn't work. want execute exit in signmcli.

#!/bin/bash -xv  signmcli=/opt/sign/eabss7024/bin/signmcli  if [ -f "$filecheck" ];         sudo $signmcli         exit; fi 

if following, works:

#!/bin/bash -xv  signmcli=/opt/sign/eabss7024/bin/signmcli  if [ -f "$filecheck" ];         echo 'exit' |sudo  $signmcli fi 

but, want execute multiple commands in signmcli. there anyway redirect control signmcli , after executing commands, control comes back?

you can execute multiple commands using semicolon operator in script.

cmd1 ; cmd2 ; cmd3 ... 

in case, suggest use ; or &.

    echo 'exit'; sudo  $signmcli 

this basic usage of commands.

* a; b    run , b, regardless of success of * && b  run b if succeeded * || b  run b if failed * &     run in background.
