linux - How to run multiple composed commands (with multiple arguments) in gnu parallel? -

i want run following scripts different input arguments using gnu parallel in parallel:

rscript svmrscript_v2.copy.r 0.1 1 #(1) 0.1 , 1 input arguments rscript svmrscript_v2.copy.r 0.1 2 #(2) rscript svmrscript_v2.copy.r 0.1 5 #(3) rscript svmrscript_v2.copy.r 0.1 10 #(4) 

so wanna run 'commands' (1),(2),(3),(4) in parallel using gnu parallel.

my best guess

parallel rscript < svmrscript_v2.copy.r ::: 0.1 1 ::: 0.1 2 ::: 0.1 5 ::: 0.1 10 

i know entirely wrong , i'm getting following error: fatal error: cannot open file ':::': no such file or directory.

any suggestion need change?

thanks in advance.

the obvious is:

parallel rscript svmrscript_v2.copy.r 0.1 ::: 1 2 5 10 

but have feeling might want 0.1 , 0.2 later:

parallel rscript svmrscript_v2.copy.r ::: 0.1 0.2 ::: 1 2 5 10 

if order of arguments wrong:

parallel rscript svmrscript_v2.copy.r {2} {1} ::: 0.1 0.2 ::: 1 2 5 10 

did have chance watch the intro videos , walk through tutorial?
