Chmod changes the mode of the named file to mode.
If the file is a symbolic link, it changes the mode of the link's target.
If there is an error, it will be of type *PathError.
A different subset of the mode bits are used, depending on the
operating system.
On Unix, the mode's permission bits, ModeSetuid, ModeSetgid, and
ModeSticky are used.
On Windows, only the 0o200 bit (owner writable) of mode is used; it
controls whether the file's read-only attribute is set or cleared.
The other bits are currently unused. For compatibility with Go 1.12
and earlier, use a non-zero mode. Use mode 0o400 for a read-only
file and 0o600 for a readable+writable file.
On Plan 9, the mode's permission bits, ModeAppend, ModeExclusive,
and ModeTemporary are used.
