RunGrepTest

#! /bin/sh

# Run pcre2grep tests. The assumption is that the PCRE2 tests check the library
# itself. What we are checking here is the file handling and options that are
# supported by pcre2grep. This script must be run in the build directory.

# CODING CONVENTIONS:
# * Put printf arguments in single, not double quotes to avoid unwanted
#     escaping.
# * Use \0 for binary zero in printf, not \x0, for the benefit of older
#     versions (and use octal for other special values).

# Set the C locale, so that sort(1) behaves predictably.

LC_ALL=C
export LC_ALL

# Remove any non-default colouring and aliases that the caller may have set.
