Hello mksh developer, A customer of ours is currently in the process of migrating from legacy ksh to mksh. Overall it's going well, however they have reported one difference which causes trouble to them.
In mksh, "print -R" is not as close to "echo" as it was in original ksh. Specifically, after "-R", mksh's print command keeps parsing the command line in search of options, and stops as soon as it finds an option it doesn't recognize. In contrast, echo and the orignal ksh's print command with -R will simply print anything that doesn't look like a supported option to them. Example with the original ksh: $ print -R -42 -42 Same example with mksh: $ print -R -42 mksh: print: -4: unknown option I looked at the mksh code and was able to modify the print_c function to get mksh's print command to behave the same with -R as echo and the original ksh print with -R. I have a patch ready. Are you interested in it, or is the different behavior on purpose? Thanks, -- Jean Delvare SUSE L3 Support
