Hi, The following description is confusing to me. Since "--nocheck-order" is default, I'm wondering how can I not to give it?
I tried specifying --nocheck-order in the command line, the warnings disappear. So by default, --nocheck-order is not specified? ".. If the option ‘--nocheck-order’ is given, unsorted inputs will never cause an error message. If neither of these options is given, wrongly sorted inputs are diagnosed only if an input file is found to contain unpairable lines, and when both input files are non empty." "‘--nocheck-order’ Do not check that both input files are in sorted order. This is the default." Suppose that the joining field in both files are sorted by some ordering that 'join' don't know (for example, the joining field is a concatenation of a string and a number), what options should be used to join files with such ordered joining fields? -- Regards, Peng
