+Subject: [PATCH] tests: Fix head options for BusyBox compatibility
+
+BusyBox does not accept the GNU coreutils shorthand forms:
+ head -1
+
+It requires:
+ head -n 1
+
+This causes RunGrepTest test data to fail on
+Yocto-based systems that use BusyBox.
+
+Replace all occurrences of `head -1` → `head -n 1`
+
+This aligns the scripts with POSIX syntax and fixes failing
+grep tests in RunGrepTest (including testtrygrep).
+
+Upstream-Status: Inappropriate [oe-specific]

The PCRE2 RunGrepTest script uses the Gnu Coreutils form: head -1 Busybox does not support this shorthand option and reports: head: invalid option --'1' which cause the grep tests fail when running ptest on yocto. Replace head -1 with head -n 1 . This makes RunGrepTest work correctly.
