How to put an entry in crontab using only one command ?

Hi:

Please, Is there any way to put an entry in crontab using only one
line command ?

I need put this command in 30 solaris's crontabs machines:

00 23 * * * * * /var/adm/monitor/collector > /var/adm/monitor/
collector.log

by "one line command", I assume you want to avoid the interactivity of
'crontab -e':
crontab -l > tmpfile && echo "new entry" >> tmpfile && crontab tmpfile

For performing this on multiple boxes, I'd use expect.

Hmm, with a tmpfile this is 100% safe.

For Solaris (any SysV cron??) I found that crontab buffers already,
so

(
crontab -l
echo "new entry"
) | crontab

works as well.

BTW the OP's "new entry" seems to have too many fields, should be:

"00 23 * * * /var/adm/monitor/collector > /var/adm/monitor/collector.log"
