- Infos on CRONRGF.CMD
- ====================
-
- CRONRGF.CMD was modelled after the "cron"-utility of Unix. It allows you to
- specify in a control files on which times and dates a command should be executed
- repeatedly.
-
- CRONRGF.CMD starts and runs forever, dispatching the commands at the given
- times.
-
- Please check ATRGF.CMD which was modelled after the OS/2-LAN-command "at" for
- another variant having features not found in CRONRGF.CMD.
-
- Usage
- =====
-
- CRONRGF [/T] [/M] [/R[nn]] [/B] cronfile
-
-
- Reads file 'cronfile' and executes command[s] repeatedly according to it.
- 'cronfile' has to be formatted like in Unix; unlike the Unix-version a '%' is
- treated like any other character; empty lines and ones starting with
- a semi-colon (;) or a (#) are ignored.
-
- Switch '/T[estmode]': the cronfile is read and the user is presented with the date/times
- and commands to be executed upon them. The planned and truly scheduled
- times are written to the log-file.
-
- Switch '/M[idnight]': all commands which were scheduled the same day, starting from
- midnight to the time of first invocation are executed once.
-
- Switch '/R[nn]': check cronfile at least every 'nn' (default 60) minutes whether it changed; if so, reread
- it immediately and set the new schedule-times. If set, the cronfile will be checked for changes after
- executing commands
-
- Switch '/B[lackAndWhite]': do not colorize output strings (e.g. for usage in more, less etc.).
- This switch merely suppresses the ANSI-color-sequences attached to the
- strings.
-
- example: CRONRGF /TEST testcron
- execute statements in file 'testcron' in testmode
-
- example for a control-file:

- # This is a comment too (starts with the Unix-comment symbol)
- ; empty lines are ignored too...

- ; you can give a list of values, separated by a comma (,), e.g. "1,3,7"
- ; you can give a range of values, separated by a dash (-), e.g. "1-5"
- ; you can give a star (*) instead of a value, meaning entire range of all valid values
