dash: Execute a specific script and stop at the first [e]rror.
$ dash -e ${path-to-script-sh}
try on your machine

The command "dash -e ${path-to-script-sh}" is invoking the dash shell and passing it the "-e" option along with the path to a script file. Here's an explanation of each component:

  • "dash": Dash is a shell, also known as the Debian Almquist shell, typically used as a lightweight and fast alternative to the bash shell. It is compatible with the POSIX (Portable Operating System Interface) standard for Unix-like systems.

  • "-e": The "-e" option, also known as the "errexit" or "exit-on-error" option, is used to cause the shell to exit immediately if any command or pipeline within the script returns a non-zero exit status (indicating an error).

  • "${path-to-script-sh}": This is a placeholder that should be replaced with the actual path to a specific script file (ending with the ".sh" extension). The "${...}" construct is used in shell scripting to access and expand the value of a variable.

By executing the "dash -e" command followed by the desired script file path, you are instructing the dash shell to run the script while immediately exiting if any part of it encounters an error.

This explanation was created by an AI. In most cases those are correct. But please always be careful and never run a command you are not sure if it is safe.
