t9001 used a '\n' in a sed expression to split one line into two lines, but the usage of '\n' in the "replacement string" is not portable. The '\n' can be used to match a newline in the "pattern space", but otherwise the meaning of '\n' is unspecified in POSIX. - Gnu versions of sed will treat '\n' as a newline character. - Other versions of sed (like /usr/bin/sed under Mac OS X) simply ignore the '\' before the 'n', treating '\n' as 'n'. For reference see: pubs.opengroup.org/onlinepubs/9699919799/utilities/sed.html http://www.gnu.org/software/sed/manual/sed.html As the test already requires perl as a prerequisite, use perl instead of sed.
