Way too complicated! Here's a simplified version of the script:
-----8<----- cut below ------8<--------------------------
#!/bin/bash
SIZE=$(stat -c "%s" $1)
for ((i=0; i<SIZE; i++))
do
read -n1 CHAR
test -z "$CHAR" && echo || echo -n "$CHAR"
sleep 0.1
done < $1
------8<----- cut till above line ----8<----------------
Save as slowtype.sh and make it executable. Run as below:
./slowtype.sh /etc/passwd
> $ cat randtype.py
>
> import time
> import os
> import sys
>
> f=open("/etc/passwd")
> lines=f.readlines()
>
> sys.stdout = os.fdopen(sys.stdout.fileno(), 'w', 0)
> for line in lines:
> # First indentation level
> for char in line:
> # indent all following lines with a tab
> time.sleep(0.02)
> #print "slept"
> sys.stdout.write(char)
>

The above code is completely non-pythonic (looks like a
C program written in python!). The following code must be
succinct and simpler enough:
------------ 8<------- cut below --------- 8<-----------------
#!/usr/bin/env python
import time
import sys
for char in sys.stdin.read():
sys.stdout.write(char)
sys.stdout.flush()
time.sleep(0.1)
---------- 8<------- cut till above ------ 8<------------------
Save the above script as slowtype.py and make it executable.
Run the script as below:
./slowtype.py < /etc/passwd
The same code in ruby would be something like below (even
simpler versions could be possible):
--------- 8<-------- cut below ------- 8<----------------------
#!/usr/bin/env ruby
STDIN.read.each_char do |c|
STDOUT.write c
STDOUT.flush
sleep 0.1
end
--------- 8<------ cut till above -------- 8<-------------------
Save the above script as slowtype.rb and make it executable.
Run the script as below:
./slowtype.rb < /etc/passwd
