use tr to split words

[ferreum]

fmt is an unclean way to split words, tr does this nicely.

:+1: Good stuff, thank you!

[wellle]

Hold on. It looks like this changed behavior.

[ferreum]

I can't see anything different here, what did you notice?

[wellle]

echo "a b-c" | tr -s '[:space:]' '\n' | sed -e 'p;s/[^a-zA-Z0-9_]\+/\n/g'

produces

a
a
b-c
b-c

instead of

a
a
b-c
b c

[wellle]

How about this?

echo "a b-c " | sed -e 'p;s/[^a-zA-Z0-9_]/ /g' | tr -s '[:space:]' '\n'

produces

a
b-c
a
b
c

I'll prepare a commit. Let me know if you see any downside of the switched order of sed and tr.

[ferreum]

For me, both commands produce the same lines in different order. I guess it depends on the version of sed. It's safer to tr afterwards.

[wellle]

Oh that's interesting. For the record I'm using BSD sed because I'm on Mac OS.

[wellle]

Alright, should be good now. Thanks again!
