2025-12-29: I have restored the wiki to a backup from the end of November. Starting in September 2025, accesses went form the 800MB-1.2GB range per month to 26GB in September, 42GB in October, and 70GB in November with most accesses originating from China. As soon as I realized what was causing all the access problems in November, I shut it down (it had reached 36GB by then) behind a password/login screen. The database had gotten corrupted, and I tried a restore from just before the spike in access but that didn't work. Thus, end of November. I still have the other daily backups so if there were any important additions in December, let me know and maybe they can be recovered. - Allen H.

CMP
CMP compares 2 files at the byte level. It will display the file offset and the value of the byte from every file when a difference is find.
Syntax: CMP <path1> <path2>
Example:
CMP /do/CMDS/xmode /d1/CMDS/xmode
If the files are identical, it returns
Differences None ... Bytes compared: 00000439 Bytes different: 00000000
If the files are different, the result will be something like
Differences byte #1 #2 ======== == == 00000007 80 81 00000008 66 67 0000004C 70 58 Bytes compared: 00000439 Bytes different: 00000003
