windows - Running hstart from MSYS

    I'm trying to automate some things on my computer. And here's what I ran into. I'm running this command from MSYS prompt:

    hstart /elevate "cmd /k netstat -anb"

    First a message box with title "Failed to create process - Hstart" appears, saying: "C:/Program Files (x86)/Git/elevate" A new non-elevated console is then opened with a message: "The requested operation requires elevation." It works as expected if run from cmd.exe. What is even happening and how to make it work?

    It appears MSYS performs automatic paths conversion, if it's to run an executable "not dependent on msys-1.0.dll." So for it work you can double the slash:

    hstart //elevate "cmd /k netstat -anb"

    Here are some more links, just in case.

    Why doesn't MSYS grep take options from variable?
  • superuser

    To set my default options for grep (from MSYS in Win7) to ignore object files and specific dirs, I exported GREP_OPTIONS to ~/.profile as follows:

    export GREP_OPTIONS='--exclude=*.{o,obj,pyc} --exclude-dir={.git,_Output}'
export GREP_COLOR='1;32'

    Even after restarting the shell for my .profile to take effect, my call to grep still searches object files. However, the GREP_COLOR variable seems to work. I even tried explicitly setting my options in the same shell before executing grep:

    $ grep --version
GNU grep 2.5.4

$ export GREP_OPTIONS='--exclude=*.{o,obj,pyc} --exclude-dir={.git,_Output}'
$ echo $GREP_OPTIONS
--exclude=*.{o,obj,pyc} --exclude-dir={.git,_Output}
$ grep $GREP_OPTIONS -r foo .
grep: ./bar.o: Permission denied
./baz.c:My foo text
$ grep --exclude=*.{o,obj,pyc} --exclude-dir={.git,_Output} -r foo .
./baz.c:My foo text

    How do I get grep to automatically use GREP_OPTIONS from ~/.profile?

    Try

    export GREP_OPTIONS='--exclude="*.{o,obj,pyc}" --exclude-dir={.git,_Output}'

    i.e., enclosing the --exclude filename pattern in (double) quotes.

    Try putting the variables in .profile, along with a line that says something like the following:

    alias grep='grep $GREP_OPTIONS'

    That just might fix it.
