Re: [PATCH] Use wc instead of awk to count subtrees in t0090-cache-tree

Ben Walton [off-list ref] writes:

The awk statements previously used in this test weren't compatible
with the native versions of awk on Solaris:

echo "dir" | /bin/awk -v c=0 '$1 {++c} END {print c}'
awk: syntax error near line 1
awk: bailing out near line 1

echo "dir" | /usr/xpg4/bin/awk -v c=0 '$1 {++c} END {print c}'
0

And with GNU awk for comparison:
echo "dir" | /opt/csw/gnu/awk -v c=0 '$1 {++c} END {print c}'
1

Instead of modifying the awk code to work, use wc -w instead as that
is both adequate and simpler.

Hmm, why "wc -w" not "wc -l", though?  Is somebody squashing a
one-elem-per-line output from ls-files onto a single line?
