# less the youngest file in the dir that is not a dot file.

I always seem to need a tmp file, I used to do ‘vi /tmp/foo’ but it usually had something in it from last time.  This function opens a new file and stores the file name in $f.

I use it like:

vt
<paste some stuff, clean it up>
perl -pe ’s/foo/bar/’ $f

####
function vt () {
    for i in `seq 0 255`;
    do
        FILE=/tmp/$USER-foo-$i;
        if [ -f "$FILE" ]; then
            echo -n '.';
        else
            f=$FILE;
            vi $FILE;
            echo $FILE;
            return;
        fi;
    done
}

###### Cleanup
function cleanvt () {
for i in `seq 0 255`
do
    FILE=/tmp/$USER-foo-$i

    if [ -f "$FILE" ]
    then
    echo -n '.'
    rm $FILE
    else
        echo
        return
fi
done
echo
}

No matter how good an admin you are, you’ll eventually delete something by accident.  I don’t like ‘rm -i’,  it’s too much.  I use the trick of typing ‘#’ before the rm command. Tab competion still works but if I mess up and hit tab-enter (like I do a lot) the ‘#’ saves me. When I’ve got the line looking like I want I ‘ctrl-a’ to beginning and delete the ‘#’ and execute the line.
