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.
