I am aware of all those steps. It is the syntax of the sed command that I am struggling with. If I just grep for the command and issue the
Code:
sed 's/^/#/'
#0 10 * * 5 /my/cron/job

I only get that single line in my new file. I am not strong with sed and need some help with the [address]. I have tried these and get the same error,
Code:
$ crontab -l | sed [/my/cron/job]s/^/#/
Unrecognized command: [/my/cron/job]s/^/#/
$ crontab -l | sed '[/my/cron/job]s/^/#/'
Unrecognized command: [/my/cron/job]s/^/#/

The job file is created in as follows: o creates a header describing the job as an job or a job. jobs submitted to all queues other than queue are listed as jobs. The header is: for an job, or for a job. o A set of POSIX shell commands is added to make the environment (see environ(5)) for the job the same as the current environment. o then copies text from the prototype file to the job file, except for special variables that are replaced by other text: Replaced by the current working directory. Replaced by the current file size limit (see ulimit(2)). Replaced by the current umask (see umask(2)). Replaced by the time at which the job should be run, expressed as seconds since January 1, 1970, 00:00 Coordinated Universal Time, preceded by a colon. Replaced by text read by from the standard input (that is, the commands provided to to be run in the job). o When a job is submitted to queue queue, uses the file as the prototype file if it exists. Otherwise, it uses the file EXAMPLES
The following file creates commands to change the current directory, file size limit, and umask in the job to their respective values as they existed when was originally run. These commands are inserted before the commands in the job: SEE ALSO
