,Awk etc.
I've done below things:Downloaded and installed unxutils.zip from source 
forge.Create the environment variable path when I type 'sed' and 'grep --help' 
it is working , when I used a below commandC:\Windows\System32>grep -i 'patter' 
filename.txtI'm getting below error: 'no such file or directory'. But that file 
exists on my desktop in one of the folders.I also installed wget.exe after 
googling but no luck.could you help with this how to make unixutils work on 
windows 10 64 bit OS with clear steps.Thank you.
