Remove Line that contains specific string
I am looking for a way to remove any line in a text file that contains the string "Mac address". I guess you would grep and sed, but I am not sure how to do this. Thanks for you help.

MySQL
let us assume ur input is file1.txt

cat file1.txt | grep -v "Mac address" > file2.txt

this will create a new file file2.txt without lines containing "Mac address"

hope this will help you
