Personal guidelines for writing cronjobs

crontab

# 1. Wrap lines as you wish.
# 2. Do not use tabs for indentation.
# 3. Write a blank line after each cronjob.
# 4. Use numerical values instead of names.
# 5. Set the least amount of directories in the PATH environment variable as possible.
# 6. Use the mktemp command to create files.
# 7. Delimit fields by one space character, unless more are needed.
# 8. Group cronjobs performing similar tasks (e.g deleting files) by sections.
#
#       Use a comment block to indicate a section.
#
#       For example:
#
#         ####################
#         # Delete old files #
#         ####################
#         cronjob
#
#         cronjob
#
#         cronjob
