Hello all,
Need to pick your brains,
I have a 10Gb file where each row is a name, I am expecting about 50 names in total. So there are a lot of repetitions in clusters.
So I want to do a
sort -u file
Will it be considerably faster or slower to use a uniq before piping it to sort... (3 Replies)

tcpbug
TCPBUG(1) General Commands Manual TCPBUG(1)NAME
tcpbug - TCP/IP connection bugging device
SYNOPSIS
tcpbug [-cx] [-btT] local-port remote-host remote-port
DESCRIPTION
tcpbug forwards a TCP/IP connection to port local-port on the local machine to the port remote-port on remote-host while spying on the con-
nection and writing all data passing through to standard output. All data coming from the client is printed with a greater than sign (>)
first on each line, and all data coming from the server is printed with a less than sign (<) first on each line. Any byte offsets and
time-stamps are printed before the greater than or less than sign, and are separated from each other by a colon (:).
OPTIONS -b Print the offset of the first byte in the stream for each line.
-c Display bytes as individual characters. Printable characters are displayed directly, some control characters appear as C-language
escapes (
,
, et.c), while others appear as 3-digit octal numbers. This should be similar to the -c switch of od(1).
-t Print the time at which the data was received for each line. The time is the number of seconds and microseconds, separated by a
decimal point (.), since 00:00 UTC, January 1, 1970, as reported by gettimeofday().
-T Print the time at which the data was received for each line. The time is the number of seconds and microseconds, separated by a
decimal point (.), since the connections were established.
-x Display each byte as a two digit hexadecimal number.
SEE ALSO tcpconnect(1), tcplisten(1), od(1).
BUGS
The names of the options are not yet finalized, and may change at a future release.
