Thanks you all,
Again I see that this printf we can use. But there are some scenarios where the o/p does not exactly match with echo. So still its good to have a way to pirnt -n /-e/-E with echo. Can this be considered as bug and can this be fixed?
It’s not a bug. According to POSIX.1-2008:
echoutility shall not recognize the
"--"argument in the manner specified by Guideline 10 of XBD Section 12.2;
"− −"shall be recognized as a string operand.
It is not possible to use
echoportably across all POSIX systems unless both
−n(as the first argument) and escape sequences are omitted.
echoutility has not been made obsolescent because of its extremely widespread use in historical applications.
