Shell Programming and Scripting

Hi there, I have over 2000 systems (mainly Solaris) and I want to write a script that inserts a new root cronjob on each of those servers. obviously just adding a line to /var/spool/cron/crontabs/root looks like the easiest way, but i really dont want to have to send a HUP to crond on all boxes


Do any of you guys know of a simple tried and tested way of scripting this type of thing

any advice would be greatly appreciated

How about this ?

Code:

crontab -l | awk '{print;} END { print "* * * * * echo \"hi\" >> /tmp/test111" }' | crontab -

This appends the new cron job to the existing cron entries.

thanks for the reply, however when i run that i get

Code:

# crontab -l | awk '{print;} END { print "50 14 * * * /opt/bin/myscript" }' | crontab -
crontab: can't open your crontab file.

I am root and dont have any issues when running the -l or -e flags on their own

am i missing something here?

Assuming your cron is called "root":

Code:

cd /var/tmp
crontab -l | awk '{print;} END { print "50 14 * * * /opt/bin/myscript" }' > root
crontab root
