Re: Read last expression in a file?
Hi, >> >> Run["tail -0 outputfile > tail.txt]; >> Import["tail.txt] >> >> I also tried your version: ReadList["!tail outputfile", Expression] >> but no luck with that either. >> >> Any suggestions, anyone? >> I've seen you have a version that works, but if you are interested in a version which doesn't create an intermediate file here is something that also works for me on Windows (with tail installed from the Resource Kit Tools): Import["!tail -0 \"" <> fname <> "\"", "Text"] my filename did contain spaces, so I needed the enclosing "". Actually to see what goes wrong it is useful to redirect stderr to stdout, so you can see error messages, like here: Import["!tail -0 \"" <> fname <> "\" 2>&1", "Text"] once you have the command line running, you can of course also use ReadList directly to perform the conversion to Mathematica expressions: ReadList["!tail -0 \"" <> fname <> "\"", Expression] hth, albert
