My question is regarding EXPORT command
I know everybody has their own style on coding but I wonder why do we use EXPORT to assign/call a variable to monitorscript variable?
The export keyword will make a variable visible in child processes of the process it is set in. Example: processA has a variable X=something. If processA starts a child processB the variable X will evaluate to "" (empty string) because this is a new process. The same goes for a processC started as child of processB and so on. If the variable is exported this makes no difference for processA but it will show up in processBs environment too.
Since you start one process from this process, namely:
The variable APP_DIR will be part of the environment of the started monitor-script because of the export. Without the export it would not. That has nothing to do with "style", maybe the process needs this variable set (i don't know). If not, then the export is superfluous and a simple:
would also suffice.
On a side note, this:
would be better written this way:
I hope this helps.
