Find and replace text in a file between range of lines using sed

You can use sed addresses:

sed '19,33s/google/facebook/g' file

This will run the substitution on lines between and including 19 and 33.

The form of a sed command is as follows:

[address[,address]]function[arguments]

Where 19,33 is the addreses,
substitute is function
and global is the argument

the above answer ALMOST worked for me on Mac OSX.

sed '19,33s/google/facebook/' file

worked perfectly without braces.

sed '19,$s/google/facebook/' file

works until the end of the file as well.
