Sorry that I don't speak German, but I agree that printf is more portable than echo. However, I do think there is a bug here: $ _POSIX2_VERSION=200112 POSIXLY_CORRECT=1 /bin/echo -n 'a\tb' | od -c 0000000 a \ t b 0000004 According to the POSIX 2001 standard, http://www.opengroup.org/onlinepubs/009695399/nframe.html, "On XSI-conformant systems, if the first operand is -n, it shall be treated as a string, not an option. The following character sequences shall be recognized on XSI-conformant systems within any of the arguments". Therefore, when _POSIX2_VERSION selects the 2001 standard, and POSIXLY_CORRECT is turned on, the above example should have output "-n<space>a<tab>b<newline>" rather than "a\tb", as in: $ printf -- '-n a\tb\n' |od -c 0000000 - n a \t b \n 0000007 It looks like the builtin bash echo has the same misbehavior on systems desiring to be XSI conformant. - -- Life is short - so eat dessert first!
