I seem to have a lot of small-scale, one-line, single-shot commands in the L section.
It’s a pity that I don’t have some sort of record of where most of this list came from, because it seems a lot of the entries are minor in comparison.
No matter, let’s push two or three of these along, and get to the good stuff later. Here’s ldd.
ldd is something I use on occasion when it seems a library is missing for a program that refuses to run.
ldd can show me what’s being called, but doesn’t seem to offer much more assistance than that.
There are a few flags available — printing unused dependencies, and so forth — but as far as I know, there’s not much in the way of super guru power here.
Useful in a pinch, but not much beyond that.
ldd should come with glibc in your distro.
