UNIX : Create file using vi and cat

using vi or cat

       and press
      "ESC" button
       ":wq"

done.. type "ls" you will see the new file has been created.

cat command

UNIX : Find files that contain a string

Ref for me..

find . -exec grep -l "string to find" {} \;
change the "string to find" to find your string. Please include (")

also can do this..
find . -type f | xargs grep "String to find"
