Well you guessed it right, the “global” command (or :g in command mode)
will let you select lines that match a particular pattern globally in
the file and lets you operate on the selected text. The **:v** operates
similar to **grep -v** which selects all texts which do not match the
pattern.

I have a file with ~29K lines. All lines must begin with ”\“. However somelines are broken into two, in which case the lines which do not start with ”\” need to be appended to the previous

line

Sample text:

\foo\bar

\food

bar

\x\y

\z

Should be converted to:\foo\bar

\foodbar

\x\y\z

And we solved it this way:`:v/^\\/exe "normal i\<C-H>\<ESC>"`

**Statement:**VI is perfect

**Proof:** VI in roman numerals is 6. The natural numbers less than 6
which

divide 6 are 1, 2, and 3. 1 + 2 + 3 = 6. So 6 is a perfect number. Therefore, vi

is perfect.

— Arthur Tateishi

**And a corollary**VIM in roman numerals might be: (1000 - (5 + 1)) = 994, which happens to be

equal to 2*496+2. 496 is divisible by 1, 2, 4, 8, 16, 31, 62, 124, and 248 and

1+2+4+8+16+31+62+124+248 = 496. So, 496 is a perfect number. Therefore, vim is

twice as perfect as vi, plus a couple extra bits of goodies. :-)

That is, vim is better than perfect.— Nathan T. Oelger
