avoiding temporary files

[rkdarst]

from Aalto chat:

"""one more interesting topic for me is the ways of avoiding writing tmp-like files in bash. For example, I do some “sed” and “awk” in my script several times so that every time I do > to tmp. If it is possible to avoid it or bash is not the best choice for these sort of scripts? In short, would be interesting to get some overview of different languages including short “suitable for Xs/not suitable for Xs”.
