All options may be abbreviated to the shortest non-ambiguous sub-string. If no options are given, everything is displayed. [--config] config Specify the Amanda configuration you want to display the state for. --file amdumpfile Specify an alternate file instead of the amdump or amflush file. --summary Display a summary of the state of the run. --dumping Display all partitions that are dumping. --waitdumping|wdumping Display all partitions that are waiting to be dumped. --waittaper|wtaper Display all partitions dumped that are waiting to be written to tape. --dumpingtape|dtape Display all partitions that are dumping directly to tape. --writingtape|wtape Display all partitions that are writing to tape. --finished Display all partitions that are dumped and written to tape. --failed|error Display all partitions that failed. --estimate Display all partitions whose estimate is finished. Works only during the estimate phase. --gestimate|gettingestimate Display all partitions whose estimate is not finished. Works only during the estimate phase. --stats|statistics Display statistics about active-time of taper and dumpers. --locale-independent-date-format Output the date in a locale independent format. The format is the same executing: date +'%Y-%m-%d %H:%M:%S %Z' EXIT CODE
The exit code of amstatus is the ORed value of: 0 = success 1 = error 4 = a dle failed 8 = Don't know the status of a dle (RESULT_MISSING in the report) 16 = tape error or no more tape SEE ALSO
