Each time you want to enter a command, a file named fbatch.txt
There are 3 parameters available :
./pgcycl -a minute hour monthday month weekday command output error
You can choose the interval of execution of your commands by choosing which parameters you want to fill. Here is the interval of each value :
- minute 0-59
- hour 0-23
- monthday 1-31
- month 1-12
- weekday 0-6
- output (The file of the standard output)
- error (The file of the error output)
You can also put "*" to replace an empty time/date field or just let the rest of the time/date field empty.
You must choose a command and an output/error parameter.
A command can take space by putting "''" between the parameter.
./pgcycl -l
This command let you list the differents commands you are running in a cycle.
./pgcycl -d x
This command let you delete an execution of command by choosing the line of the command you want to delete.
You can view each line with ./pgcycl -l
