pushOptE

Syntax: pushOptE

Pushes the shell option e onto a stack. The e option controls whether a script should exist on the first line that fails. If you write a function that might be called from a script with option set, and you don't want this to affect the functions operation, you can push the option using this function, then run `set +e` to clear the flag. When leaving the function, popping the stack returns the option to the state it was in before.

Example: function foo() { pushOptE; set +e; (perform some code that may return a non-zero exit code) popOptE }
