apt.sh: handle multiple origins in apt-get output

[filippog]

I found this case mostly on machines with "point release" upgrades pending, e.g. like the recent jessie and stretch updates. What do you think @SuperQ ?

[SuperQ]

Hrmm, do you have some sample output (just the Inst lines is fine)?

[SuperQ]

Ahh, ok, I found one:

Inst base-files [9.9+deb9u1] (9.9+deb9u3 Debian:9.3/stable [amd64])
Inst tzdata [2017b-1] (2017c-0+deb9u1 Debian:9.3/stable, Debian:stable-updates [all])

[SuperQ]

How about simplifying the 2nd awk with this first awk:

/usr/bin/apt-get --just-print upgrade \
  | /usr/bin/awk -F'[()]' '/^Inst/ { sub("^[^ ]+ ", "", $2); sub(" \\[", "|", $2); sub("\\]", "", $2);; print $2 }'

[filippog]

Yup | as a separator would work too, though how the final awk would look like?

[SuperQ]

Right, how about we stick to a space separator, and just eliminate all the other spaces.

/usr/bin/awk -F'[()]' \
  '/^Inst/ {
    sub("^[^ ]+ ", "", $2);
    sub("\\[", " ", $2);
    sub(" ", "", $2);
    sub("\\]", "", $2);
    print $2
  }'

[filippog]

Indeed that's even simpler, PR updated, PTAL!
