This is the converse of GH-15353 -- in addition to plenty of
scripts in the tree that are marked with the executable bit
(and so can be directly executed), there are a few that have
a leading `#!` which could let them be executed, but it doesn't
do anything because they don't have the executable bit set.
Here's a command which finds such files and marks them. The
first line finds files in the tree with a `#!` line *anywhere*;
the next-to-last step checks that the *first* line is actually of
that form. In between we filter out files that already have the
bit set, and some files that are meant as fragments to be
consumed by one or another kind of preprocessor.
$ git grep -l '^#!' \
| grep -vxFf <( \
git ls-files --stage \
| perl -lane 'print $F[3] if (!/^100644/)' \
) \
| grep -ve '\.in$' -e '^Doc/includes/' \
| while read f; do
head -c2 "$f" | grep -qxF '#!' \
&& chmod a+x "$f"; \
done

# Script for preparing OpenSSL for building on Windows.
|
|
# Uses Perl to create nmake makefiles and otherwise prepare the way
|
|
# for building on 32 or 64 bit platforms.
|
|
|
|
# Script originally authored by Mark Hammond.
|
|
# Major revisions by:

|
|
# THEORETICALLY, you can:
|
|
# * Unpack the latest OpenSSL release where $(opensslDir) in
|
|
# PCbuild\pyproject.props expects it to be.
|
|
# * Install ActivePerl and ensure it is somewhere on your path.
|
|
# * Run this script with the OpenSSL source dir as the only argument.
|
|
#
|
|
# it should configure OpenSSL such that it is ready to be built by
|
|
# ssl.vcxproj on 32 or 64 bit platforms.
