According to Dave Korn on 8/14/2008 5:44 AM:
|>> C:\Cygwin\Tools\bin\ash
|> $ ./grep -E -i -v '/ash(.exe)?$' /proc/[0-9]*/exename
|
|   Uhh, hold on.
|
|   Why does 'grep' show up in rce's output?  I mean, that's what I would
| expect to happen, and then I would expect the test to always fail.  But when
| I run the exact same command locally (from ash in cmd.exe), I don't see any
| grep process appear.
|
|   How does that work?

/proc/[0-9]*/exename is a glob.  It is expanded by the shell, prior to the
exec() of grep.  So grep's process id is excluded from the grep.
