I’m asking because string comparisons are slow, but indexing is fast, and a lot of scripts I write are in bash, which to my knowledge performs a full string lookup for every executable call. All those ls’s and grep’s would be a little bit faster without performing a string lookup on each step. Of pursecourse, this now delves into compiler optimization…optimization.
Anyways, is there a way to directly invoke a program in Linux using only its nodeinode number (assuming you only had to look it up once for all invocations)?
