9.8.4 Use variable as parameters in paths and arguments

You can use variable as parameter in paths and arguments of jobs. To replace a variable by its value, you just have to enclose a variable name with `$<' and `>'.

$ dio87d -d
$ dio87d -d
$ dio87d -d
$ dio87d -d
$ dio87c ra ref1
$ dio87c rta ref1 task1
$ dio87c rtoa ref1 task1 add always
$ 

We create three variables `arg1', `arg2' and `prefix'. Then we create a job `job1'. We use `$<...>' to replace variable by its value. `$<arg1>' will be replaced by `val1', `arg2' by `val2' and `$<prefix>' by `/usr/local'.

$ dio87c va arg1 val1
$ dio87c va arg2 val3
$ dio87c va prefix "/usr/local"
$ 
$ dio87c rja ref1 task1 job1
$ dio87c rjsa ref1 task1 job1 "$<arg1> $<arg2> $<xxx>"
$ dio87c rjsp ref1 task1 job1 "$<prefix>/bin/ls"
$

Now, we create a new day `d1' and print job information to verify that `$<...>' occurences are replaced by variable values :

$ dio87c rp ref1 "2004-03-19" d1 
$  
$ dio87c xji d1 task1 job1
Job Name: job1
Task Name:     task1
[...]
Path:          /usr/local/bin/ls
Argument:      val1 val3 $<xxx>
[...]
$

You can see that `$<xxx>' is not replaced by a value, because `xxx' is not a variable in `dio87d'. But if you create a variable named `xxx' in `dio87d', it will by replaced by value when job is launched !
