multiple lines edit by Sed command.

Suppose you have a file with 1000000 lines.. & you want to change any word. Use sed command.

For example: i have a file with name rk.conf with 80000 lines & in this file,want to change lib word with lib64. i use sed this command & my problem RESOLVED.

Command like this.

#sed -i 's/lib/lib64/g' rk.conf

Enjoy... hope this will save your time........
