| 3 | # POSIX Compliance Gap Coverage Test Suite |
| 4 | # ===================================== |
| 5 | # This test file specifically targets gaps in the existing 4 POSIX test files |
| 6 | # by comparing against IEEE Std 1003.1-2017 (POSIX.1-2017) |
| 7 | # |
| 8 | # Focus areas: |
| 9 | # - Here-document variations (<<- tab stripping) |
| 10 | # - Additional redirection operators (<>) |
| 11 | # - Complex IFS field splitting scenarios |
| 12 | # - Nested and complex parameter expansions |
| 13 | # - Command name resolution order |
| 14 | # - Complex quoting and escaping |
| 15 | # - Pipeline exit status rules |
| 16 | # - Complex arithmetic edge cases |
| 17 | # - Locale and environment variables |
| 18 | # - Builtin command edge cases |
| 19 | # - Pathname expansion edge cases |
| 20 | # - Function scope and recursion edge cases |
| 21 | # - Signal handling edge cases |
| 22 | |
| 23 | # Colors (POSIX-compliant way) |
