I already found that page, as well as other discussion, and looked up the appropriate limit in the appropriate header files. I just wasn't sure whether it was the definitive statement for this context, particularly given the odd mismatch I was seeing. While that does address the question of what the actual length limit is, it doesn't address the mismatch I saw in the error message which occurred when the path was too long. Does that error, and the associated mismatch, in fact originate from within bash? If not, where does it originate? If so, any chance of getting the mismatch fixed, so that the shebang printed when the path is too long is at least the full truncated length of what was actually searched for rather than only the leading portion of that path? - -- The Wanderer Warning: Simply because I argue an issue does not mean I agree with any side of it.
