Cronsched

Schedules a crontab-like (not real crontab) list of commands to run.

Install, build, test

To install, clone this repo into your Go path.

The application has a single third-party dependency. It uses the cheekbits/is test package to make writing tests in Go a little easier.

$ go get github.com/cheekybits/is

To build a cronsched binary (from cmd/main.go) in the root directory, run:

$ make build

To run tests, run:

$ make test

Usage

Pass the command list in via stdin.

From a file:

$ cat fixture/crontab | ./cronsched

Using hereoc:

$ ./cronsched <<EOF               
45 * /bin/run_me_hourly
* * /bin/run_me_every_minute
* 19 /bin/run_me_sixty_times
EOF

The output of the above run at 19:02 will produce:

19:45 today - /bin/run_me_hourly
19:02 today - /bin/run_me_every_minute
19:00 tomorrow - /bin/run_me_sixty_times

Time can be manually passed in via -time flag:

$ ./cronsched -time 19:02
