The answer is
If you want to avoid including the full path to awk, you need to update your PATH variable to include the path to the directory where awk is located, then you can just type
awk
to run your programs.
Go to Control Panel->System->Advanced and set your PATH environment variable to include "C:\Program Files (x86)\GnuWin32\bin" at the end (separated by a semi-colon) from previous entry.
Actually, I do like mark instruction but little differently.
I've added C:\Program Files (x86)\GnuWin32\bin\ to the Path variable,
and try to run it with type awk using cmd.
Hope it works.
Go to command windows (cmd) then type:
"c:\Progam Files(x86)\GnuWin32\bin\awk"
Quoting is an issue if you're running awk from the command line. You'll sometimes need to use \, e.g. to quote ", but most of the time you'll use ^:
w:\srv>dir | grep ".txt" | awk "{ printf(\"echo %s@%s ^> %s.tstamp^\n\", $1, $2, $4); }"
echo 2014-09-07@22:21 > requirements-dev.txt.tstamp
echo 2014-11-28@18:14 > syncspec.txt.tstamp
You can download and run the setup file. This should install your AWK in "C:\Program Files (x86)\GnuWin32". You can run the awk or gawk command from the bin folder or add the folder ``C:\Program Files (x86)\GnuWin32\binto yourPATH`.
