The command "idnits --nitcount ${filename-txt}" is used to execute the IDNITS tool and retrieve the nitcount (number of nits) for a given text file.
Here's a breakdown of the command components:
-
"idnits": This is the name of the command-line tool called IDNITS. IDNITS is a tool used to check Internet-Draft (I-D) documents for specific kinds of problems.
-
"--nitcount": This is an option or flag provided to the IDNITS tool. It instructs the tool to display the nitcount, which represents the number of nits found in the given text file.
-
"${filename-txt}": This component represents the placeholder for the actual name of the text file you want to analyze. It's enclosed in the "${}" syntax to indicate that it will be replaced with the desired filename when executing the command. In this example, the assumption is that the filename has the ".txt" extension.
To use this command, you would replace "${filename-txt}" with the actual filename. For instance, if you have a text file named "my_draft.txt", the command would be: "idnits --nitcount my_draft.txt".
Running this command will execute the IDNITS tool on the given text file, and the tool will display the nitcount, which represents the number of nits found in the file.
