EXIT without parameters cause issues in the script

Software ResiliencyCode Reliability

Why you should care

The KSH script starts at the first and essentially ends when the code encounters an “exit” or the last line. When exiting a code without parameters, it causes the code to become unreliable and cause errors that tend to become unmanageable.

Business Impacts

It is recommended to have parameters in the script because lack of parameters will cause reliability issues leading to an unproductive and unmanageable code.

Production Risk

How we detect

This code insight shows when using exit with no parameters the default behavior is to exit with the return code of the last command executed. If you want to manage errors in your script, you must control your own error code system and return a specified value.
