# searching
/joe/e : cursor set to End of match
/joe/e+1 : cursor set to End of match plus 1
/joe/s-2 : cursor set to Start of match minus 2
/^joe.*fred.*bill/ : normal
/^[A-J]\+/ : search for lines beginning with one or more A-J
/begin\_.*end : search over possible multiple lines
/fred\_s*joe/i : any whitespace including newline
/fred\|joe : Search for FRED OR JOE
/\([^0-9]\|^\)%.*% : Search for absence of a digit or beginning of line
/.*fred\&.*joe : Search for FRED AND JOE in any ORDER!
/\
/\<\d\d\d\d\> : Search for exactly 4 digit numbers
/\D\d\d\d\d\D : Search for exactly 4 digit numbers
/\<\d\{4}\> : same thing
# finding empty lines
/^\n\{3} : find 3 empty lines
# Specify what you are NOT searching for (vowels)
/\c\v([^aeiou]&\a){4} : search for 4 consecutive consanants
# using rexexp memory in a search
/\(fred\).*\(joe\).*\2.*\1
# Repeating the Regexp (rather than what the Regexp finds)
/^\([^,]*,\)\{8}
# visual searching
:vmap // y/
:vmap
# searching over multiple lines \_ means including newline
/ : search for multiple line comments
/fred\_s*joe/i : any whitespace including newline
/bugs\(\_.\)*bunny : bugs followed by bunny anywhere in file
:h \_ : help
# search for declaration of subroutine/function under cursor
:nmap gx yiw/^\(sub\
# multiple file search
:bufdo /searchstr
:argdo /searchstr
# How to search for a URL without backslashing
?http://www.vim.org/ : search BACKWARDS!!! clever huh!
----------------------------------------
#substitution
:%s/fred/joe/igc : general substitute command
:%s/\r//g : Delete DOS returns ^M
# Is your Text File jumbled onto one line? use following
:%s/\r/\r/g : Turn DOS returns ^M into real returns
:%s= *$== : delete end of line blanks
:%s= \+$== : Same thing
:%s#\s*\r\?$## : Clean both trailing spaces AND DOS returns
:%s#\s*\r*$## : same thing
# deleting empty lines
:%s/^\n\{3}// : delete blocks of 3 empty lines
:%s/^\n\+/\r/ : compressing empty lines
# IF YOU ONLY WANT TO KNOW ONE THING
:'a,'bg/fred/s/dick/joe/igc : VERY USEFUL
# duplicating columns
:%s= [^ ]\+$=&&= : duplicate end column
:%s= \f\+$=&&= : same thing
:%s= \S\+$=&& : usually the same
# memory
:s/\(.*\):\(.*\)/\2 : \1/ : reverse fields separated by :
:%s/^\(.*\)\n\1/\1$/ : delete duplicate lines
# non-greedy matching \{-}
:%s/^.\{-}pdf/new.pdf/ : delete to 1st pdf only
# use of optional atom \?
:%s#\<[zy]\?tbl_[a-z_]\+\>#\L&#gc : lowercase with optional leading characters
# over possibly many lines
:%s/// : delete possibly multi-line comments
:help /\{-} : help non-greedy
# substitute using a register
:s/fred/
:s/fred/\=@a/g : better alternative as register not displayed
# multiple commands on one line
:%s/\f\+\.gif\>/\r&\r/g | v/\.gif$/d | %s/gif/jpg/
# ORing
:%s/suck\|buck/loopy/gc : ORing (must break pipe)
# Calling a VIM function
:s/__date__/\=strftime("%c")/ : insert datestring
# Working with Columns sub any str1 in col3
:%s:\(\(\w\+\s\+\)\{2}\)str1:\1str2:
# Swapping first & last column (4 columns)
:%s:\(\w\+\)\(.*\s\+\)\(\w\+\)$:\3\2\1:
# filter all form elements into paste register
:redir @*|sil exec 'g#<\(input\|select\|textarea\|/\=form\)\>#p'|redir END
:nmap ,z :redir @*
# increment numbers by 6 on certain lines only
:g/loc\|function/s/\d/\=submatch(0)+6/
# better
:%s#txtdev\zs\d#\=submatch(0)+1#g
:h /\zs
# increment only numbers gg\d\d by 6 (another way)
:%s/\(gg\)\@<=\d\+/\=submatch(0)+6/
:h zero-width
# find replacement text, put in memory, then use \zs to simplify substitute
:%s/"\([^.]\+\).*\zsxx/\1/
# Pull word under cursor into LHS of a substitute
:nmap
# Pull Visually Highlighted text into LHS of a substitute
:vmap
----------------------------------------
# all following performing similar task, substitute within substitution
# Multiple single character substitution in a portion of line only
:%s,\(all/.*\)\@<=/,_,g : replace all / with _ AFTER "all/"
# Same thing
:s#all/\zs.*#\=substitute(submatch(0), '/', '_', 'g')#
# Substitute by splitting line, then re-joining
:s#all/#&^M#|s#/#_#g|-j!
# Substitute inside substitute
:%s/.*/\='cp '.submatch(0).' all/'.substitute(submatch(0),'/','_','g')/

# replace string with contents of a file, -d deletes the "mark"
:g/^MARK$/r tmp.ex | -d
----------------------------------------
# Global combined with substitute (power editing)
