Os presentamos a Cronw 2.0, un "crontab" para Windows freeware y desarrollado bajo licencia GPL, que nos permitirá ejecutar programas a intervalos de tiempo, o cuando se cumpla una determinada fecha.

Dispone de un interface sencillísimo repleto de características y funcionalidades,

Muy interesante

New features in 2.0:
* complete rewrite of cronw which includes better source file naming and provides a solid basis for future extensions
* greatly improved logging - increase logging output without the need to restart the service
* use mnemonics inside crontab.txt (e.g. say "Mon-Fri" instead of "0-5")
* cron dir support: If you want to execute a job one time a day just put it into the dir cron.daily (same goes for cron.weekly and cron.monthly)
* syntax checking for crontab.txt
* lower system payload - crontab is only parsed if it has changed
* scripting features supported by CMD.exe - write "echo "Hello World" > C: estfile.log" in the crontab

Features that are already present in 1.x:
* 1,15 in the day field means execution on the 1st and 15th of every month
* 1-10 is equivalent to 1,2,3,...,10
* */5 in the minutes fields means that the command should be executed every five minutes.
* the ability to combine all the above features.
