I'm not sure if this is more of a SuperUser or UnixLinux question, but I'll try here...Recently, I found this:#710689 - aptitude: use unicode character in the trees - Debian Bug report logsIt would be nice when aptitude would use unicode characters for the trees in the  dependency lists, e.g. instead of:--\ Depends (3)   --- libc-dev-bin (= 2.17-3)   --- libc6 (= 2.17-3)   --- linux-libc-dev --\ Suggests (2)   --- glibc-doc (UNSATISFIED)   --\ manpages-dev...... and I thought - wow, I really like that ASCII-art tree output, wasn't aware that aptitude could do that! So, I start messing for an hour with aptitude command line switches - and I simply cannot get that output? So my initial question was - where does that output come from in the first place?!After a while, I realized that on my system, aptitude ultimately symlinks to /usr/bin/aptitude-curses; and I finally realized that aptitude has a curses interface! :/ So, I finally run aptitude without any arguments - and so the curses interface starts, and I can see something like this:... so quite obviously, those ASCII tree characters come from the curses interface.So I was wondering - is there a Debian/apt tool, which will output such a visual ASCII tree - but with actual dependencies of packages? I know about debtree - Package dependency graphs (also software recommendation - How to visually display dependencies of a package? - Ask Ubuntu); but I'd rather have something in terminal, resembling a directory tree (rather than the unordered [in terms of node position] graphs from debtree, generated by graphviz's dot). I've also seen Is there anything that will show dependencies visually, like a tree?, which recommends:$ apt-rdepends aptitudeReading package lists...

So, the question is - is there a tool, that would produce a dependency tree graph with terminal characters - like, say, in the following pseudocode:$ pseudo-deb-graph --show-package=aptitudeaptitude  --- Depends: libapt-pkg4.10  --\ Depends: libboost-iostreams1.42.0 (>= 1.42.0-1)     --- Depends: libbz2-1.0     --- Depends: libc6 (>= 2.4)  --\ Depends: libc6 (>= 2.3.6-6~)     --\ Depends: libc-bin (= 2.13-0ubuntu13)        --- ...     --\ Depends: libgcc1        --- ...     --\ Depends: tzdata        --- ......
Output visual (ASCII) Debian dependency tree to terminal?
