Text substitution

: S/old/new//Replaces the first occurrence of old in a row with new
: s/old/new/g//Replace all old in line with new
: n,m s/old/new/g//Replace all old from N to M with new
:%s/old/new/g//Replace all old in 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 resolve this problem, use "<" to specify the beginning of the matching word:

< Span style= "Color:rgb (51,51,255)" >           :%s/<four/4/g
Obviously, this will make a mistake when dealing with "fourty". Use   ">"   to resolve this issue:
        :%s/<four>/4/g
If you're coding, you might just want to replace comments in
        &NBSP;:%S/<FOUR>/4/GC

Word Exact match substitution
