Special operators for shell scripting¶

KDAriane is provided with basic components for executing shell scripts.

• parameters (p),
• input (i)
• output (o) you want.

The operators are named "eval" + p + i + o and call the eponymous .sh script.

When an operator is executed, Ariane launches the script (for example script.sh) associated to the operator with giving the following arguments:

script.sh parameter-1 parameter-2 ... parameter-p input-1 input-2 ... input-i output-1 output-2 ... output-o

In Ariane, every operator has a return value, even if it has no output.
