Retrieves information about a file or directory. The first version uses the syntax
y = fileattrib(filename)
where filename is the name of a file or directory. The returned structure contains several entries, corresponding to the attributes of the file. Here is a list of the entries, and their meaning:
Name - the full pathname for the file archive - not used, set to 0 system - not used, set to 0 hidden - set to 1 for a hidden file, and 0 else. directory - set to 1 for a directory, and 0 for a file. UserRead - set to 1 if the user has read permission, 0 otherwise. UserWrite - set to 1 if the user has write permission, 0 otherwise. UserExecute - set to 1 if the user has execute permission, 0 otherwise. GroupRead - set to 1 if the group has read permission, 0 otherwise. GroupWrite - set to 1 if the group has write permission, 0 otherwise. GroupExecute - set to 1 if the group has execute permission, 0 otherwise. OtherRead - set to 1 if the world has read permission, 0 otherwise. OtherWrite - set to 1 if the world has write permission, 0 otherwise. OtherExecute - set to 1 if the world has execute permission, 0 otherwise. You can also provide a wildcard filename to get the attributes for a set of files e.g.,
y = fileattrib('foo*')
You can also use fileattrib to change the attributes of a file and/or directories. To change attributes, use one of the following syntaxes
y = fileattrib(filename,attributelist) y = fileattrib(filename,attributelist,userlist) y = fileattrib(filename,attributelist,userlist,'s')
where attributelist is a string that consists of a list of attributes, each preceeded by a + to enable the attribute, and - to disable the attribute. The valid list of attributes that can be changed are
'w' - change write permissions 'r' - change read permissions 'x' - change execute permissions for example, '-w +r' would indicate removal of write permissions and addition of read permissions. The userlist is a string that lists the realm of the permission changes. If it is not specified, it defaults to 'u'.
'u' - user or owner permissions 'g' - group permissions 'o' - other permissions ("world" in normal Unix terminology) 'a' - equivalent to 'ugo'. Finally, if you specify a 's' for the last argument, the attribute change is applied recursively, so that setting the attributes for a directory will apply to all the entries within the directory.
