pseudo_tty

Here are two tiny utilities, pty and timestamplines.

In concert, they allow you to timestamp the output of an arbitrary command like so:

$ pty some-command | timestamplines

or

$ pty some-command | timestamplines -f > log &
$ tail -f log

Scripts

pty

Run a script so that it thinks it is is connected to a terminal, and therefore flushes its output after every line. It solves the "line buffering problem".

timestamplines

Print all lines on STDIN to STDOUT but prepend a time stamp.

Also provided is slowprint to test it
