This means that the -3d counts from the beginning of the pattern?? In my
file The first occurrence of the patten expands from line 1 to line 82.
Yes, from the beginning of the pattern
Yakov
How can I force it to delete 3 lines from the end?
Disclaimer: Everything below is untested.
Normally, an HTML page should have only one <BODY> tag. The following
should do (without :g)
:1|/\c<body\>/-3d
If you may have, before <HTML>, a <BODY> which mustn't trigger a deletion:
:1|/\c<\@<=html\>/;/\c<body\>/-3d
If (your original command) you may have several <HTML> tags in a single
file, and the single line 3 lines above the next <BODY> tag must be
deleted... well, I think it's doable but I won't venture a command.
Note: \c in a pattern means "disregard case", \> means "end-of-word",
x\@<= means "if preceded by x". The latter is used here (in the second
example) to avoid missing <HTML> at the start of line 1.
Best regards,
Tony.
