When you encounter the error message “command line error: too short switch: -o”, it means that you have used the “-o” switch in a command line command, but the switch is missing some required parameters.
In command line interfaces, switches are used to modify or specify the behavior of a command. They are usually preceded by a hyphen (-) or double hyphen (–). Switches are followed by parameters or arguments that provide additional information to the command.
In the case of the “-o” switch, it requires a parameter that specifies the output file or location where the command should write its output. The parameter should be provided immediately after the switch, without any spaces in between. For example:
command -o output.txt
In the above example, “command” is the actual command you’re running, and “output.txt” is the parameter value for the “-o” switch. The command will write its output to a file named “output.txt”.
If you encounter the “command line error: too short switch: -o” message, it means that you have not provided the required parameter after the “-o” switch. It could be due to a typo or missing parameter. Make sure that you specify the parameter immediately after the switch, without any spaces.
