FUNCTION DOCUMENTATION

Top

grou2gid($)

This function receives a group name and converts it to the group id.

gid2group($)

This function receives a group id and returns the group name associated with that id.

get_gid($)

This routine receives a file name and returns the group id ownership of that file. The function dies if the file does not exist. The function uses the standard "stat" function to get the relevant information.

get_group($)

This routine receives a file name and returns the group name of that file. The function throws an exception if anything goes wrong.

check_gid($$)

This routine receives a file and a group id. It makes sure that the file is of the appointed group. It will throw an exception if it is not.

check_group($$)

This method receives a file and a group name. It makes sure that the file is of the appointed group. It will throw an exception if it is not.

check_hash_gid($$$)

The function receives a hash reference, a group id and a verbose flag. This routine runs a check on all the files in the hash that they are indeed of the designated group received.

check_hash_group($$$)

This does exactly as the above function check_hash_gid except it receives a group name and not an absolute id, and then translates it to an absolute id in order to make the check and simple calls: check_hash_gid.

TEST($)

Test suite for this module. The test suite could be called individually or by a higher level script to perform regression testing for this class as part of a bigger class collection. This test suite currently does nothing.
