Adds useful cron manipulation functions to the Wick environment. Performs no actions.
Examples
wickFormula cron
Returns nothing.
Add a job to cron. Takes additional arguments and passes them to wickMakeFile from the wick-base formula.
- $1 - The name of the job to create.
- $2 - The file in the formula to use for the cron job.
- $3-@ - Additional arguments to pass to
wickMakeFile, such as--template.
The job name should be simple alphanumeric characters. Try to avoid things that make regular expressions hard or ones that do not work well as filenames. For example, *super* job! is a bad name, super-job is far better.
The job file may be placed into a new file or appended to a list of cron jobs in a single file, so it is best to avoid setting environment variables in it. Instead, you could call a shell script that sets environment variables, if you require that feature.
File contents need to have the following fields for a job definition, in order: minute, hour, day, day of month, month, day of week, username, command. For more information, see man 5 crontab and remember that these are system jobs so they require an account name.
Examples
# Adds a job from files/delete_files.cron
cronAdd delete_files delete_files.cron
# Uses a template instead
cronAdd rebuild_index --template rebuild_index.cron.sh
Returns nothing.
Removes a job from cron. Works only for jobs that were added with cronAdd.
- $1 - The name of the cron job to remove.
Examples
# Add and remove a cron job
cronAdd update-mongo-v2 --template update-mongo.mo
cronRemove update-mongo-v1
Returns nothing.
