LOGROLL
Added September 2019
LOGROLL {fspec1{,...fspecN}} {/switches}
LOGROLL rolls over—rotates—log files, for example events.log -> events.l01 -> events.l02, etc. It's a commonly accepted technique for keeping the current log file from getting endlessly large, while at the same time being able to maintain a number of historical/archived copies.
Switches

Meaning |
|---|---|
Switches affecting user interface: |

/Q |
Query/prompt for confirmation on each file |
/F |
Force confirmation—i.e., roll over without asking |
Switches limiting selection of files to roll over: |
|
/MINDAYS:### |
Roll over only files not modified in at least ### days |
/MINSIZE:#### |
Roll over only files larger than #### blocks |
Switches limiting number of generations of rolled-over files kept: |
|
/MAXDAYS:### |
Discard rolled-over copies beyond ### days old |
/MAXGENS:### |
Discard rolled-over copies beyond ### generations |
Comments
Retention of rolled-over copies stops after MAXDAYS or MAXGENS, whichever comes first. Defaults: DAYS=unlimited, GENS=5. If GENS < 100, rolled-over copies will use extension x##, where x is the first character of the original extension. Else rolled-over copies will use extension ### (001,002,...).
