How can I exit a script without exiting the invoking shell?
The return bash builtin will exit the sourced script without stopping the calling (parent/sourcing) script. Causes a function to stop executing and return the value specified by n to its caller. If n is omitted, the return status is that of the last command executed in the function body. …
Are there executables outside of the bash script?
Depending on the designation and version number of your bash interpreter some commands may not be available. External commands are executables accessible outside of a bash script like curl. Unlike functions, external commands are not stored as variables. The lower the precedence of a command type, the later the command may be interpreted.
How to kill a script running in terminal, without closing?
One is to stop the script ( Ctrl Z ), get the PID of the script and send SIGKILL to the process group. When a command is executed in a shell, the process it starts and all its children are part of the same process group (in this case, the foreground process group). To send a signal to all processes in this group, you send it to the process leader.
Why does shell-Bash stop on error in sourced script?
In a sourced script, however, using set -e will kill the original shell if a later command exits with an error status. A trivial solution would be to set +e at the end of the script, but this would break the parent’s set -e if used (which may very well happen if someone wraps my script in the future).
Is there any way to exit a script and then stay in the terminal?
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?

How to return an exit code in Bash?

How can I skip the rest of a script?
I have a bash script, where I call exit somewhere to skip the rest of the script when getopts doesn’t recognize an option or doesn’t find an expected option argument.
When to stop or exit a PowerShell script?
Stop or exit a PowerShell script when it errors. Unlike other programming languages, the PowerShell scripting language has two types of error scenarios: terminating and non-terminating. Both of these types of errors are “bad,” but by classifying them differently, the scripter can handle them differently.
Why is write-host not terminating in PowerShell?
Write-Host ‘Continuing script regardless if file exists or not…’ The script will continue executing code whether or not that file exists as shown below. This is a non-terminating error example because Write-Error did not terminate the script at line two. Instead, it returned the error to the console and kept going.
How to invoke a terminating error in PowerShell?
One way a scripter can invoke a terminating error is by using the throw keyword. This PowerShell construct creates a terminating error while also throwing an exception. Using the example above, let’s say that file is critical and we’d like to stop script execution if it doesn’t exist. We could replace Write-Error with throw instead.
