Usage

cronv [OPTIONS]

Options:
  -f, --file <PATH>   Edit a crontab file directly instead of the system crontab
  -V, --version       Print version and exit
  -h, --help          Print this help and exit

cronv                        # Edit the current user's system crontab
cronv --file ~/jobs.cron     # Edit a crontab file directly
cronv -f ~/my-jobs.cron      # Same, short form

Note: system-wide crontabs that carry a user column (e.g. /etc/crontab, /etc/cron.d/*) use a 6-field format that cronv does not parse — stick to per-user crontabs or plain 5-field files.

Schedule syntax

┌───── minute       (0–59)     */5  0,15,30,45  10-20
│ ┌─── hour         (0–23)     */2  9,17  8-18
│ │ ┌─ day-of-month (1–31)     */5  1,15  1-7
│ │ │ ┌ month       (1–12)     */3  2-4   JAN,JUN,DEC
│ │ │ │ ┌ weekday   (0–7)      1-5  0,6   MON-FRI  (0/7 = Sunday)
* * * * *

When both day-of-month and weekday are restricted, the job fires when either matches (Vixie cron semantics).

Next-run times are computed in local time; daylight-saving transitions are approximated (a run scheduled inside a DST jump may be off by the shifted hour).
