NAME

is_writable - Check for writability of a file.

SYNOPSIS

is_writable [ -g ] file

DESCRIPTION

is_writable can check a file to see if a file is either writable by group or by all, returning either 0 if it is writable, or non-zero if it is not. is_writable also checks the parent directories, if a complete path is given, for writeability. Options are:

-g: Check for group writability as well as world.

BUGS

The Andrew File System, or Mach, or the combination of the two, apparently plays games with stat(), the way I get the file info, so it can report things as writable, when they aren't.
