In Ksh, echo hello world and print hello world will return the same output (hello world). What is the difference between these text processing commands with respect to the Korn Shell?
I know how they work in BaSH, Cshell, and tcsh.

Q12. Why does [ksh] have print since echo already exists [and] is widely used?A12. The behavior of echo varies from system to system. The POSIX standard does not define the behavior of echo when the first argument beings with a - or when any argument contains a \ character. This makes echo pretty useless for use in portable scripts.

and by that logic (no portability) isn't print useless too? :/ It's use with tcsh csh and bash is completely different than with ksh which more resembles PRINT in BASIC than UNIX imo. Nov 21, 2016 at 18:30
