352. Installing coreutils and sed, gawk on Windows (without cygwin)

My third Windows XP post. Only a few more to go...

You can also set up all these tools via cygwin: http://verahill.blogspot.com.au/2013/03/353-cygwin-with-octave-and-gnuplot-on.html

1. coreutils
coreutils covers a fair number of the basic linux file tools. In particular cat, paste and join are of interest with respect to data processing.

A. Go to http://sourceforge.net/projects/gnuwin32/files/coreutils/5.3.0/coreutils-5.3.0.exe/download?use_mirror=waix&download= and download coreutils-5.3.0.exe. Run the file.

B. Make sure to add C:\Program Files\GnuWin32\bin to the PATH:
* Right-click on my computer, select properties, Advanced.
* Click on Environment variables
* In the second box, 'system variables', highlight 'Path' and click on 'Edit'. In the variable value box, add ';C:\Program Files\GnuWin32\bin'

C. Go to the start meny, click on Run..., and type in 'cmd'
In the (fake) DOS window, type e.g. ls -lah to see if everything works.

2. gawk
Go to http://gnuwin32.sourceforge.net/packages/gawk.htm and open http://downloads.sourceforge.net/project/gnuwin32/gawk/3.1.6-1/gawk-3.1.6-1-setup.exe

Run the .exe and use the default installation location (which is the same as the coreutils above -- so you don't have to add a separate path). Run cmd and do e.g.

cat ntuser.ini|gawk "{print $2}"

S e t t i n g s ; T e m p o r a r y

3. sed
Sed is installed like gawk -- go to http://gnuwin32.sourceforge.net/packages/sed.htm and go to http://gnuwin32.sourceforge.net/downlinks/sed.php

Run the .exe file and install in the default location. Try e.g.

cat ntuser.ini|sed "s/e/E/g"
