C Scope alternative

This function really helps as a cscope alternative. check for any variable as "f "

function f() {

local i o m

set -f

test "$ffo" || ffo='! -iname tags'

for i in "$@"; do

case "$i" in

c) ffo='-iname *.[chs]' ;;

h) ffo='-iname *.[h]' ;;

x) ffo='-iregex .*\.[chs][xp+]?[xp+]?' ;;

p) ffo='-iname *.php*' ;;

q) ffo='! -iname tags' ;;

-*) o="$o $i" ;;

*) m="$m $i" ;;

esac

done

test "$m" || return

find . $ffo -type f -print0 \

| xargs -0 grep --colour=always --binary-file=without-match -n $o "${m# }" \

| tee ~/.ff~

set +f

}

function v() {

local cmd

test -s ~/.ff~ || return

if [ "$*" ]; then

grep "$*" ~/.ff~ > ~/.ff- || return

cmd="vim +`head -1 ~/.ff- | cut -d: -f2` `head -1 ~/.ff- | cut -d: -f1 | uniq`"

history -s $cmd

$cmd

else

perl -pe 's/\033[^a-z]*[a-z]//g' ~/.ff~ > ~/.ff

vim -q ~/.ff -c :cw5

fi

}

alias vv='cat ~/.ff~'
