Handy addition to the "mount | column -t" trick:

You can use this within Vim to pretty-format text tables, initialization of variables, etc. Just highlight the lines in question in visual line mode (V) and type

    !column -t
to pipe the lines through the column command.

faucet 80 --in cat This is useful for creating a connection for receiving the input of what you get... e.g. running faucet 80 --in cat and later curl http://127.0.0.1:80 will deliver to you console : GET / HTTP/1.1 User-Agent: curl/7.21.4 (i686-pc-linux-gnu) libcurl/7.21.4 OpenSSL/0.9.8n zlib/1.2.5 libidn/1.19 Host: 127.0.0.1:900 Accept: /

Just some additional information:

Faucet is part of "netpipes", which is available for most Unixoid operating systems. I guess it was inspiration to build "netcat". But netcat was a absolute terrible hack of a program, so "socat" (socket-cat?) was born.

In case you need the functionality of bash's /dev/tcp [1] and you are pondering to install netcat or netpipes, do yourself a favor and just go for socat, it's insanely more powerful, read the manpage, read the examples!

tsort. It's pointless until you need it, but when you need it, it's totally awesome.

less. Overkill, but SO MUCH BETTER THAN tail -f. Seriously. You can toggle "follow mode" without losing your place in the incoming stream.

When rewriting large amounts of ASCII text (or comments in Code), I really find "par" helpful.

    : Just use it in :
    : vi with your cursor in front of a badly wrapped block of text. :
    : Press !}par and the text will be :
    : piped to par :
    : which fixes up :
    : the :
    : formatting and keeps aligned frame markers :
