Slow the Terminal Down

1 min read · fun

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

1ff=/tmp/bashpipe
2mkfifo $ff
3( 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:

 1slow () 
 2{ 
 3    unset VISUAL;
 4    EDITOR=ed;
 5    alias ls='dir -F';
 6    export PS1='[$?] \W $ ';
 7    ff=/tmp/bashpipe_$(date +%s);
 8    mkfifo $ff 2> /dev/null;
 9    ( cat $ff | perl -We 'use Time::HiRes;$|++;while(read(STDIN,$c,1)){Time::HiRes::usleep(15000);print $c;}' ) & exec &> $ff;
10}

Then type:

1exec bash
2slow
