Re: generate a dependencies list

[Pablo Lorenzzoni <spectra@debian.org>]

Hello!

That's exactly what I've already tried. :-) See... I've reported that in my 
previous email. The problem is that it gives the complete dependency list 
(and I can parse that), but I couldn't figure out how to discover what a 
virtual package (reported between < and > by apt-cache) depends on.

I've done this in shell script:

GEN_LIST=/file/with/the/list

function depends() {
    DEPS=`apt-cache depends $1 | grep Depends | cut -f 2 -d ':'`;

    for PKG in $DEPS; do

        if [ ! `grep $PKG $GEN_LIST` ]; then

            echo $PKG >> $GEN_LIST;
            cat $GEN_LIST | sort -u > $GEN_LIST.2;
            mv $GEN_LIST.2 $GEN_LIST;
            
            depends $PKG;
        fi

    done
}

It works, but I still have to figure out how to treat virtual packages (such 
as awk).

| Try 'apt-cache depends PkgName' and you should get a list of the
