class HFileSys

_HADES_CLASS_DESCRIPTION



 HDiskFile,HDiskDir,HDiskCatalog,HFileSys

 tool set to build a catalog of a full filesystem including all
 meta information of files and dirs. The catalog can be updated
 incremental by rescanning only dirs which have been modfied since
 last scan.

Function documentation

void getUsers(map<uid_t,TString>& musers)

 gather all user known by the system

void getGroups(map<gid_t,TString>& mgroups)

 gather all groups known by the system

map<uid_t,TString> initUsers()

 helper function to init static maps

map<gid_t,TString> initGroups()

 helper function to init static maps

void fillSysInfo()

 gather user and group infos from the
 system

Bool_t getUser(uid_t uid, TString& name)

 lookup of user uid in the map of
 known users. if the user can not be
 found the the user name will be unknown_uid

Bool_t getGroup(gid_t gid, TString& name)

 lookup of group gid in the map of
 known groups. if the group can not be
 found the the group name will be unknown_gid

void getModTime(time_t lastmod, TString& modtime)

 translates time_t lastmod into string
 witrhout trailing \n

void getFileSize(ULong64_t size, TString& out)

 returns human readable file size (K,M,G,T units)

void lsFiles(TString directory, vector<TString>& fileList, Bool_t clear = kTRUE, Bool_t fullpath = kFALSE)
