Subject: t7614: avoid hiding git's exit code in a pipe
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b6b276974e727f4ac92fbaef972f2cd59b3071dd;p=thirdparty%2Fgit.git

t7614: avoid hiding git's exit code in a pipe

The exit code of the upstream command in a pipe is ignored, so in

	git cat-file commit HEAD | sed -e "1,/^\$/d" >actual

a crash of "git cat-file" would go unnoticed: the exit code of the
pipeline is that of "sed", which happily succeeds on empty input. The
test would thus pass even though "git cat-file" failed.

Write the output of "git cat-file" to a file first and run "sed" on
that file, so that the exit codes of both commands are checked by the
&&-chain.
