Linux / Windows – what’s the difference…

Nifty feature to change text inside large file over Linux commandline

sed -i 's/original/new/g' file.txt

sed = Stream EDitor
-i = in-place (i.e. save back to the original file)
s = the substitute command
original = a regular expression describing the word to replace (or just the word itself)
new = the text to replace it with
g = global (i.e. replace all and not just the first occurrence)
file.txt = the file name
