perm − permute inputs to outputs
perm o1,o2 ...
perm will read data from multiple inputs, and output each input to the specified output. perm is implemented by invoking dgsh-tee with the -p option.
o1,o2 ...
Permute the inputs to the specified outputs. The comma-separated arguments o1,o2, ... specify the number of the output channel (starting from 1) where the corresponding nth input channel will be sent. Thus, input 1 goes to output o1, input 2 goes to output o2, and so on. As an example a cross-permutation is specified with the argument 2,1.
