How do I grep with sed and substitute a "#" on that line
Hey all,
I am trying to disable a certain cronjob before I run a backup. I want to be able to add/remove a "#" from the beginning on the crontab line it is located on.
Here is the crontab:
Does anyone know how to grep the "watchdog" line and add a "#" to it. Also to go backwards have a line that removes the "#" from that line so I can enable it after the backup.
My code removes the top 3 lines that are duplicated in script each time, then it comments out the "watchdog" line to disable the cronjob. I have a couple issues, one is that my script is messy:
My other issue is if the "watchdog" line is already commented out then this script adds an aditional comment to the line giving me:
##*/5 * * * * /opt/watchdog/sstartupWatchdog.sh
If I was to run the enable script it will just delete one of the comments.

Hello experts,
I know line number of the word I want to replace. Can "sed" substitute word on a specific line?
As well, can sed substitute words inside a specific patten.
ex. <word>lalala</word> #replace anything between <word> and </word>

However, when I put this in my script to... (3 Replies)
