I want to filter only file paths :

i try :

rpm -qpl dhad-9.0.27891-2.x86_64.rpm | find -type f

Also :

rpm -qpl dhad-9.0.27891-2.x86_64.rpm|grep -f

Also :

rpm -qpl dhad-9.0.27891-2.x86_64.rpm |ls -f

All didn't work.

files

  1. Well that was horrible. Provided the output is sorted like this though, we can look at it backwards:

    1. Take the last line
    2. Lop off anything after the last / and store it, and move on to the next line up
    3. If the line doesn't equal the last directory name, print
    4. Move up the output and go back to step 2.

    To keep the order, we also need to re-reverse the output. Thankfully there's a little command called tac (the reverse of cat) to make this simple. We just call it before and after our Bash scripting:

    ... | tac | while read p; do [ "$l" != "$p" ] && echo "$p"; l="$(dirname "$p")"; done | tac

    Note that this will only ever work if we can rely on the file order. I think we probably can; I've only ever seen package files sorted like this so I assume it's standard.

    When trying to answer this, I started using a different method with awk. I seem to give most of my answers in awk-form these days so here's the above as seen by awk:

    ... | tac | awk 'l!=$0{print}{sub(/\/[^\/]*$/,"",$1);l=$0}' | tac

    It's a little shorter but I doubt it's any faster.

  2. It seems like README and LICENSE are files. So you could try,

    rpm -qpl dhad-9.0.27891-2.x86_64.rpm | grep -P '.*\..*|README|LICENSE'
    • 0

  3. You'd need to test each file path I think e.g. something like

    some command \
| xargs -I{} sh -c 'test -f "$0" && printf "%s\n" "$0"' {}

    or

    while read -r f; do 
  [[ -f "$f" ]] && printf "%s\n" "$f"
done < <(some command)
