To find the chmod numerical value (also known as the file permission mode) for a file or directory on FreeBSD, use the stat command with the %A format specifier.
For example, to find the chmod value for a file named file.txt, you would run the following command:
stat -f %A file.txt
This will return the chmod value in octal format, such as 0644 or 0775.
You can also use the ls command with the -l option to view the chmod value, along with other file information:
ls -l file.txt
The first column of the output will show the file’s permissions, including the chmod value. The first character indicates the type of the file, followed by nine characters that represent the permissions for the owner, group, and other users.
