Debate

Watching the debate is painful. The baseball game is more interesting, even if the Dodgers who I want to win, are losing 5-0 to the Phillies. :)

McCain’s facial expressions are very awkward.

vij

Posted by jmrodri on

I’ve been using a bash function for launching vim for quite a while. I can do things like vij edit.jsp and it would find the edit.jsp and launch vim. The original version looked like this:

vij ()
{
find . -name "$1" -exec vim {} \;
}

The problem would occur when there were more than one file named edit.jsp. Running find . -name edit.jsp yielded four files:

find . -name edit.jsp
./code/webapp/WEB-INF/pages/activationkeys/edit.jsp
./code/webapp/WEB-INF/pages/errata/edit.jsp
./code/webapp/WEB-INF/pages/channel/manage/edit.jsp
./code/webapp/WEB-INF/pages/systems/probes/edit.jsp

vij would exec vim for each of the files found. This is not what I wanted, I only wanted to edit the third one. So with a little hacking I updated it to prompt me if it found more than one, so I could choose the one I wanted.

vij edit.jsp

Multiple matches found...
1: ./code/webapp/WEB-INF/pages/activationkeys/edit.jsp
2: ./code/webapp/WEB-INF/pages/errata/edit.jsp
3: ./code/webapp/WEB-INF/pages/kickstart/wizard/profile/advanced/edit.jsp
4: ./code/webapp/WEB-INF/pages/channel/manage/edit.jsp
5: ./code/webapp/WEB-INF/pages/systems/probes/edit.jsp
q: Quit

?

Simply add this to your $HOME/.bashrc and you’ll be all set.

vij ()
{
    dafiles=$(find . -type f -name "$1")
    matches=$(echo $dafiles | gawk '{print NF}')

    case "$matches" in
        0)
           echo "No matches found"
           show=""
           ;;
        1)
           show=$dafiles
           ;;
        *)
           echo
           echo "Multiple matches found..."
           i=1
           for option in $dafiles
           do
              echo "$i: $option"
              i=`expr $i + 1`
           done
           echo "q: Quit"
           echo
           read -p "? " ans
           if [ "q" == "$ans" ]; then
              show=""
           else
              show=$(echo $dafiles | gawk '{print $"'"$ans"'"}')
           fi
           ;;
    esac

    if [ "" != "$show" ]; then
       vim $show
    fi
}
