Any way to exit bash script but not quitting the terminal

Question

When I use exit command in a shell script  the script will terminate the terminal  the prompt   Is there any way to terminate a script and then staying in the terminal   My script run sh is expected to execute by directly being sourced  or sourced from another script   EDIT  To be more specific  there are two scripts run2 sh as        run sh echo  place A        and run sh as      exit       when I run it by   run2 sh  and if it hit exit codeline in run sh  I want it to stop to the terminal and stay there  But using exit  the whole terminal gets closed    PS  I have tried to use return  but echo codeline will still gets executed

It s correct that sourced vs  executed scripts use return vs  exit to keep the same session open  as others have noted   Here s a related tip  if you ever want a script that should keep the session open  regardless of whether or not it s sourced   The following example can be run directly like foo sh or sourced like   foo sh source foo sh  Either way it will keep the session open after  exiting   The    string is passed so that the function has access to the outer script s arguments      bin sh foo        read -p  Would you like to XYZ   Y N     response         response     y     amp  amp  return 1      echo  XYZ complete  args            return 0      echo  This line will never execute      foo         Terminal result        foo sh     Would you like to XYZ   Y N   n       foo sh     Would you like to XYZ   Y N   n          terminal window stays open and accepts additional input    This can be useful for quickly testing script changes in a single terminal while keeping a bunch of scrap code underneath the main exit return while you work  It could also make code more portable in a sense  if you have tons of scripts that may or may not be called in different ways   though it s much less clunky to just use return and exit where appropriate

1  exit 0 will come out of the script if it is successful   2  exit 1 will come out of the script if it is a failure   You can try these above two based on ur req

if your terminal emulator doesn t have -hold you can sanitize a sourced script and hold the terminal with      bin sh sed  s exit return g  script  gt  tmp script    tmp script read   otherwise you can use  TERM -hold -e script

To write a script that is secure to be run as either a shell script or sourced as an rc file  the script can check and compare  0 and  BASH SOURCE and determine if exit can be safely used   Here is a short code snippet for that     X  basename  0      X  basename  BASH SOURCE      amp  amp        echo        executing  name src as a shell script                 echo        sourcing  name src

The  problem  really is that you re sourcing and not executing the script  When you source a file  its contents will be executed in the current shell  instead of spawning a subshell  So everything  including exit  will affect the current shell   Instead of using exit  you will want to use return

Yes  you can use return instead of exit  Its main purpose is to return from a shell function  but if you use it within a source-d script  it returns from that script   As  sect 4 1  Bourne Shell Builtins  of the Bash Reference Manual puts it         return  n        Cause a shell function to exit with the return value n     If n is not supplied  the return value is the exit status of the   last command executed in the function     This may also be used to terminate execution of a script being executed   with the    or source  builtin  returning either n or   the exit status of the last command executed within the script as the exit   status of the script     Any command associated with the RETURN trap is executed   before execution resumes after the function or script     The return status is non-zero if return is used outside a function   and not during the execution of a script by   or source

This is just like you put a run function inside your script run2 sh  You use exit code inside run while source your run2 sh file in the bash tty  If the give the run function its power to exit your script and give the run2 sh its power to exit the terminator  Then of cuz the run function has power to exit your teminator           bin sh       use   run2 sh      run                 echo  this is run           return 0         exit 0            echo  this is begin      run     echo  this is end    Anyway  I approve with Kaz it s a design problem

Actually  I think you might be confused by how you should run a script  If you use sh to run a script  say  sh   run2 sh  even if the embedded script ends with exit  your terminal window will still remain  However if you use   or source  your terminal window will exit close as well when subscript ends  for more detail  please refer to What is the difference between using sh and source

I think that this happens because you are running it on source mode with the dot    myscript sh   You should run that in a subshell    full path to script myscript sh    source  http   ss64 com bash source html

I had the same problem and from the answers above and from what I understood what worked for me ultimately was    Have a shebang line that invokes the intended script  for example      bin bash uses bash to execute the script   I have scripts with both kinds of shebang s  Because of this  using sh or   was not reliable  as it lead to a mis-execution  like when the script bails out having run incompletely   The answer therefore  was    Make sure the script has a shebang  so that there is no doubt about its intended handler  chmod the  sh file so that it can be executed   chmod  x file sh  Invoke it directly without any sh or        myscript sh     Hope this helps someone with similar question or problem

You can add an extra exit command after the return statement command so that it works for both  executing the script from the command line and sourcing from the terminal   Example exit code in the script      if      -lt 2    then      echo  Needs at least two arguments       return 1 2 gt  dev null      exit 1    fi   The line with the exit command will not be called when you source the script after the return command   When you execute the script  return command gives an error  So  we suppress the error message by forwarding it to  dev null

Instead of running the script using   run2 sh  you can run it using sh run2 sh or bash run2 sh  A new sub-shell will be started  to run the script then  it will be closed at the end of the script leaving the other shell opened

Also make sure to return with expected return value  Else if you use exit when you will encounter an exit it will exit from your base shell since source does not create another process  instance
