grep on windows powershell

howto find contents inside files on windows 7 or windows 8

created by gsavix with notepad++

on windows7 or windows8 you could find contents of some type of files.
For example for search all .php files for application weberp to see what of them have
information about word "wiki" (and do not care about lower case or upper case) you run:

1) on menu start run powershell that will start a window with powershell, something like a linux terminal;

2) inside windows powershell run:  ls | select-string wiki

this command will show all files that have string wiki lower or upper case.
see that you will see file name and line number where string occurs.

See one real example for where weberp version 4.11.3 handle wiki.

for help with power shell use help ls
