Hi everyone,
I'm experiencing a strange issue where ps does not find all the processes
if it's run from a top level junction to the main cygwin directory in cmd :
On an older windows install I had cygwin under c:\cygwin64 , this time I
used chocolatey to install it and it put it under c:\tools\cygwin. To keep
things consistent so as not to break users I decided to make a junction :
Directory of C:\
01/04/2018 03:01 PM <JUNCTION> cygwin64 [c:\tools\cygwin]
running ps from cygwin works fine :
$ ps -p 6376
PID PPID PGID WINPID TTY UID STIME COMMAND
6376 1 6376 5464 pty2 197608 23:52:31
/cygdrive/c/Windows/system32/cmd
however running it from the junctioned top level directory does not work :
C:\>c:\cygwin64\bin\ps -p 6376
c:\cygwin64\bin\ps -p 6376
PID PPID PGID WINPID TTY UID STIME COMMAND
but when launched via the actual path it works properly :
C:\>c:\tools\cygwin\bin\ps -p 6376
c:\tools\cygwin\bin\ps -p 6376
PID PPID PGID WINPID TTY UID STIME COMMAND
6376 1 6376 5464 pty2 197608 23:52:31
/cygdrive/c/Windows/system32/cmd
any ideas what's causing this?
Thanks,
Sabuj
