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.
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.
Hello all,

Hello experts,
I know line number of the word I want to replace. Can "sed" substitute word on a specific line?

CRON(8) System Manager's Manual CRON(8)NAME
cron - daemon to execute scheduled commands (Vixie Cron)
SYNOPSIS
cron
DESCRIPTION
Cron should be started from /etc/rc or /etc/rc.local. It will return immediately, so you don't need to start it with '&'.
Cron searches /var/spool/cron for crontab files which are named after accounts in /etc/passwd; crontabs found are loaded into memory. Cron
also searches for /etc/crontab and the files in the /etc/cron.d/ directory, which are in a different format (see crontab(5)). Cron then
wakes up every minute, examining all stored crontabs, checking each command to see if it should be run in the current minute. When execut-
ing commands, any output is mailed to the owner of the crontab (or to the user named in the MAILTO environment variable in the crontab, if
such exists).
Additionally, cron checks each minute to see if its spool directory's modtime (or the modtime on /etc/crontab) has changed, and if it has,
cron will then examine the modtime on all crontabs and reload those which have changed. Thus cron need not be restarted whenever a crontab
file is modified. Note that the Crontab(1) command updates the modtime of the spool directory whenever it changes a crontab.
