use of parallel in bash script

[Dietmar Pils]

dear developer or maintainer of GNU parallel,

how can I use parallel in a bash script? what do I miss, but the snippet

time cat RUM.sam | parallel --pipe --files -N 5184953 sort -k 3,3 -k 
4,4n | parallel -mj1 sort -k 3,3 -k 4,4n -m {} ";" rm {} > sort.sam

works from the command lane but not in a bash script.

what have I to do, that I can run the same from inside a bash script...


best wishes
