Description: The ‘ErrorCode’ in the context of command-line interfaces refers to a number that indicates the success or failure of a command executed in the terminal. This code is fundamental for process management in Unix-like operating systems, as it allows users and shell scripts to determine whether a command executed successfully or if an error occurred. By convention, an error code of ‘0’ indicates that the command executed successfully, while any other number represents a specific type of error. Error codes are especially useful in task automation, as they allow scripts to make decisions based on the results of previous commands. Additionally, error codes can be used to debug issues in scripts and applications, facilitating the identification of failures and the implementation of appropriate solutions. In summary, the ‘ErrorCode’ is an essential tool for effective interaction with the command line, providing critical information about the execution status of commands.
