OK, it may be part of the official standard now, but that version of the standard *just* came out this year. I wouldn't expect it to be anywhere close to universal adoption for a couple years. That's about how long it takes to roll out new versions of system software in production enviroments. hobbit:~$ dpkg -l dash | tail -n1 ii dash 0.5.12-2 amd64 POSIX-compliant shell hobbit:~$ dash $ x=$'hi\tmom'; printf %s\\n "$x" $hi\tmom Debian 13 will probably come out next year. Maybe that version of Debian will have a dash shell with this feature added. Maybe it won't; I haven't checked the changelogs. Either way, it's not widespread yet, and one shouldn't expect it to be available outside of bash.
