Yeah, sorry. I actually wrote everything in one line. When pasting it
into the mail, my editor inserted the line breaks and I just added a few
backslashes where I thought appropriate.
The actual problem I have when copy-pasting it back is that I didn't
quote the regular expression "^Installed-Size". Since it is in the
beginning of a line, bash interpreted it as a "quick substitution". JFTR
a copy-pasteable version:
for p in $( apt-cache show xserver-xorg-video-all | grep ^Depends | \
cut -d: -f2 | sed -e 's#,##g'); do apt-cache show $p | grep \
"^Installed-Size" | cut -d: -f2; done | awk ' BEGIN { s=0 } { s+=$1 }
END { print s }'
The line before END doesn't needs it's newline escaped because of the
open single-quoted string.
