  • variables and percent sign handling are ignored
  • the hostname parameter of hcron - conv is required in order to fill in the hcron host field
  • optionally, an email address can be provided using the --mail option in order to fill in the hcron notify_email field

...

Code Block
crontab -l > crontab.copy
mkdir crontab.conv
hcron- conv --to-events hcron-server crontab.copy crontab-conv

...

  • each event file in a specified directory is used to generate a single crontab entry
  • if the hcron host field is not empty, the command for the new crontab entry is prepended with ssh <host>
  • variables and comments are ignored
  • optionally, a remote shell other than ssh can be specified using the --remoteShell option
