I remember using crontab -r assuming that -r is to open it in read only mode. like vim -R
Bad assumption!
Some platforms it's -r, others it's -d. I suspect it's down to which cron daemon you run but never really cared enough to investigate. In any case, both are next to the 'e' key so either are just as dangerous in terms of typos.
