Here are some examples of using the pathchk command in Linux:

1. To check if a file named “example.txt” has a valid filename (no invalid characters, not too long), you can use the following command:

pathchk example.txt

2. To check if a directory named “example_dir” has a valid pathname, you can use the following command:

pathchk -p example_dir

3. To check if the current directory has a valid pathname, you can use the following command:

pathchk -p .

4. To check if the maximum pathname length is set to 255 characters, you can use the following command:

pathchk -L

5. To check all the files in the current directory for valid filenames, you can use the following command:

pathchk *

Note that the pathchk command is used to check if a file or directory path conforms to certain conventions, such as the maximum pathname length, and the presence of invalid characters in the filename. The output will be nothing if the path is valid, otherwise the error message will be displayed.
