i doubt few people have noticed, but i've rewritten lddtree recently in |
| 2 |
python. i did for speed, for fun, and to add a lot more functionality that |
| 3 |
would have driven the bash code base to new perverse levels. |
| 4 |
|
| 5 |
i've randomly stumbled across places in our code base (beyond ebuilds) where |
| 6 |
the new python version would be useful. rather than try and ferret out those |
| 7 |
myself, i'll just announce here and people can sort it out. |
| 8 |
|
| 9 |
if you guys think this can satisfy most of your needs but there's like a small |
| 10 |
edge case that isn't quite handled, let me know. i can always add another |
| 11 |
option :). |
| 12 |
|
| 13 |
specifically, lddtree (both the shell & python variants) support a --list: |
| 14 |
$ lddtree -l /bin/bash |
| 15 |
/bin/bash |
| 16 |
/lib64/ld-linux-x86-64.so.2 |
| 17 |
/lib64/libreadline.so.6 |
| 18 |
/lib64/libhistory.so.6 |
| 19 |
/lib64/libncurses.so.5 |
| 20 |
/lib64/libdl.so.2 |
| 21 |
/lib64/libc.so.6 |
| 22 |
this way you don't have to resort to grep/awk/sed on the output to try and get |
| 23 |
the names out of `lddtree` (or heaven forbid, `ldd`). |
| 24 |
|
| 25 |
it also supports --root just like you'd expect: |
| 26 |
$ lddtree -l /bin/bash --root /mnt/space/distros/x86 |
| 27 |
/mnt/space/distros/x86/bin/bash |
| 28 |
/mnt/space/distros/x86/lib/ld-linux.so.2 |
| 29 |
/mnt/space/distros/x86/lib/libreadline.so.6 |
| 30 |
/mnt/space/distros/x86/lib/libncurses.so.5 |
| 31 |
/mnt/space/distros/x86/lib/libdl.so.2 |
| 32 |
/mnt/space/distros/x86/lib/libc.so.6 |
| 33 |
|
| 34 |
but things get even crazier with the new --copy-to-tree option (python version |
| 35 |
only). this is useful for scenarios like kernel initramfs where you want to |
| 36 |
copy over one or two ELFs and their dependencies w/out resorting to statically |
| 37 |
linking them. check out the --help text for more details. |
