Those three variants are identical when > presented to the shell. True for standard Linux/UNIX shells; not necessarily true on other platforms. The Windows cmd.exe interpreter, for example, does not perform dequoting or argument splitting - those are performed by the application, typically in the C startup code, and the Microsoft C startup code doesn't recognize the single-quote character. Of course on Windows you have the option of using a UNIX shell such as bash, in which case you'll get the behavior Jordan describes. But it's not universal. For that matter, on Linux or UNIX a user could be running some oddball shell that doesn't support one of those quote characters - it'd be a strange thing to do, but it's possible. Or be running something like bash, but have IFS set to include the "." character. The basic point is solid - those three variants may well be indistinguishable to the application (almost certainly if running on UNIX or Linux). But it's not 100% guaranteed. -- Michael Wojcik Distinguished Engineer, Micro Focus -- openssl-users mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-users
