The OP expected, strangely enough, the line number of the input file, not the line number of the source file. Frank -- Dipl.-Inform.

Obviously that is what perl is complaining about. Solution: just escape the dash with a leading backslash. However, I doubt that will produce the effect you are looking for. Are you really, really sure you want that character set there? To me it looks much more like you want a literal match of the text 'acyl-carrier protein'. >Unfortunately the error message does not tell me which line of which file >leads to the problem. First I didn't believe you but a quick test confirms that you are right. The perl interpreter does not print a file/line information (tried it on 5.6.1). Wierd! >Could anybody advise? Just grep your files for the offending m/// instruction. Something similar to grep "acyl-carrier protein" *.pl jue |
