I've made some small adjustments including file name and variable name changes. Also, I've tightened up the test to expect exactly one stat-like call: (Since I've changed your commit, I'll wait for an ACK before pushing it) And I've marked this issue as "done".

Count only the number of stat calls compared to --help. This also reduces back to "1" the number of expected calls, effectively reverting part of 2011-06-01 commit, ccf2d9a4. --- tests/ls/stat-free-color | 15 ++++++++++++--- 1 files changed, 12 insertions(+), 3 deletions(-) diff --git a/tests/ls/stat-free-color b/tests/ls/stat-free-color index b1c4744..1288560 100755 --- a/tests/ls/stat-free-color +++ b/tests/ls/stat-free-color @@ -49,13 +49,22 @@ MULTIHARDLINK 00 EOF eval $(dircolors -b color-without-stat) +# The system may perform additional stat-like calls before main. +# To avoid counting those, first get a baseline count by running +# ls with only the --help option.
