Slow the Terminal Down	fun

Slow the terminal to the old rates with a pipe and perl:

ff=/tmp/bashpipe
mkfifo $ff
( cat $ff | perl -We 'use Time::HiRes;$|++;while(read(STDIN,$c,1)){Time::HiRes::usleep(15000);print $c;}' ) & exec &> $ff

• Try running dir and dir -F!
• Don't run interactive commands like vim or top!

You can make it into a bash function by putting this into your ~/.bashrc:

slow () 
{ 
    unset VISUAL;
    EDITOR=ed;
    alias ls='dir -F';
    export PS1='[$?] \W $ ';
    ff=/tmp/bashpipe_$(date +%s);
    mkfifo $ff 2> /dev/null;
    ( cat $ff | perl -We 'use Time::HiRes;$|++;while(read(STDIN,$c,1)){Time::HiRes::usleep(15000);print $c;}' ) & exec &> $ff;
}

Then type:

exec bash
slow
