using sed to do find replace in a file.md

adapted from here

I had a huge file I wanted to find replace in and it was seeming to make Sublime Text unresponsive so I tried

sed 's/transmit 0.780000/transmit 0.97/g' <test_78.txt >test_97.txt

and it worked great. The INPUT file is test_78.txt and OUTPUT file is test_97.txt.

Generalized, it would be

sed 's/TEXT_TO_FIND/TEXT_TO_REPLACE/g' <INPUT_FILE >OUTPUT_FILE

where the < and > are important. (I am familiar with using > in Bash for redirecting.)
