Hi Everyone,
I'm not sure if this is expected. I'm working on CentOS 7, x86_64,
fully patched.
I expected to see the PHP file below classified as a PHP script, like:
# file -b rest.php
PHP script, ASCII text
I did not see any Gotcha's listed for the file command at
https://www.pixelbeat.org/docs/coreutils-gotchas.html.
Jeff
# file --version
file-5.11
magic file from /etc/magic:/usr/share/misc/magic
# ls -Al profileinfo.php
-rw-r----- 1 root apache 12531 Sep 24 17:35 profileinfo.php
# file -b profileinfo.php
C++ source, UTF-8 Unicode text
# cat profileinfo.php

/**
* Simple interface for displaying request profile data stored in
* the wikis' primary database.
*
* See also https://www.mediawiki.org/wiki/Manual:Profiling.
*
* To add profiling information to the database:
*
* - set $wgProfiler['class'] in LocalSetings.php to a Profiler class
other than ProfilerStub.
* - set $wgProfiler['output'] to 'db' to force the profiler to save its the
* information in the database.
* - apply the maintenance/archives/patch-profiling.sql patch to the database.
* - set $wgEnableProfileInfo to true.
