Text substitution

:s/old/new.///Replace the first occurrence of the old
:s/old/new/g????? Replace all old
:n,m?s/old/new/g??/ /Replace all old
:%s/old/new/g???/ Replace all old

in the current file with new

Simple substitution expressions
?????:%s/four/4/g
the "%" range prefix indicates that the substitution is performed on all rows, The last "G" tag represents all the matching points in the replacement row, If you are only working on the current line, just remove the%

If you have a word like "thirtyfour", the above command will go wrong. In this case, the word will be replaced with "Thirty4″." To solve this problem, use the " < " to specify the beginning of a matching word:

?:%s/<four/4/g
Obviously, this will make a mistake when dealing with "fourty". With ? " > "

If you're coding, you might just want to replace the comments "Four", while preserving the code. Since this is difficult to specify, you can add a "C" tag to the replacement command so that Vim prompts you before each replacement:
????

Word Exact match substitution

Sed-e "s/\<old\>/new/g"? File
