[PATCH 2/4] tests: convert nearly all `...` expressions to $(...) |
|
Date: |
Tue, 3 Apr 2012 22:25:34 +0200 |
From: Jim Meyering <address@hidden>
Exempt init.sh because it runs before we're assured to have a
shell that groks $(...). Exempt *.mk because "$" would have to
be doubled, and besides, any `...` expression in a .mk file is
almost certainly evaluated before init.sh is run. Finally, also
exempt the perl-based tests, because perl's `...` cannot be
converted to $(...). Do that by running this command:
git grep -l '`.*`' tests \
| grep -Ev 'init\.sh|\.mk$' | xargs grep -Lw perl \
| xargs perl -pi -e 's/`(.*?)`/\$($1)/g'
One minor fix-up change was required after that, due to how
quoting differs:
diff --git a/tests/chmod/equals b/tests/chmod/equals
- expected_perms=$(eval 'echo \$expected_'$dest)
+ expected_perms=$(eval 'echo $expected_'$dest)
Also, transform one file that was needlessly excluded above:
(it uses perl, but is mostly bourne shell)
perl -pi -e 's/`(.*?)`/\$($1)/g' tests/du/long-from-unreadable
