Subject: tests: init.sh: use "sed 1q" in place of "head -1"
X-Git-Tag: v8.13~100
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1d919fbb7fc5e75e3bf2835f9e2fccbe179b7d69;p=thirdparty%2Fcoreutils.git

tests: init.sh: use "sed 1q" in place of "head -1"

* tests/init.sh (warn_): Use "sed 1q" in place of "head -1".
The latter is officially obsolete but more portable than "head -n1".
Reported by Bernhard Voelker.
