Ah, recursively. Sorry.
#!/bin/sh
test $# -gt 0 || {
echo usage: $0 package >&2
exit 1
}
pkg=`pkg_info -I $1 2>/dev/null | awk '{print$1}'`
test -n "$pkg" || {
echo package $1 not recognized >&2
exit 1
}
dir=/var/db/pkg/$pkg
test -d "$dir" || {
echo $dir does not exist >&2
exit 1
}
{
echo $pkg
cat $dir/+REQUIRING 2>/dev/null | xargs -r -n1 $0
} | sort -u
This lists the dependencies recursively
- just pipe the output through 'pkg_info -s'.
(Damn, I like the "| xargs $0" bit a lot.)
Am I reading pkg_info(1) wrong, or is there really
not a trivial way to list the recursive dependencies
of a given package (the opposite of -R) in pkg_info
itself?
