Top Forums UNIX for Beginners Questions & Answers Remove duplicate email Post 303041739 by rbatte1 on Tuesday 3rd of December 2019 07:30:24 AM

A clunky way:-
Code:
grep -Ei "x.*\.com" /path/to/dir/file.html | sort -u > /path/to/dir/file.txt

The expression looks for an x followed by any number of characters followed by .com however this is not anchored to the beginning or end of a line. What is your input data like?

This input would still give some confusing results:-
Code:
x123@hello.com
x123@hello.com.foo
hello1@xyz.com
hello2@xyz.com
hello1@not-xyz.com-either

..... and lots of other variations. It leaves me a few questions::-
  • What precise conditions do you want for the search in the first place?
  • What output do you want? The full email address or just the domain.

We are adjust the search to get just records you are after, but the search needs to be precise, e.g. does the line start with x or have x immediately after @; does .com have to end the line etc. All sorts of rules can be written if you can be sure what you want. If you could post a representative sample of your input and desired output (in CODE tags) then that will give us more to work with.




Kind regards,
Robin

NAME
irsend - basic LIRC program to send infra-red commands SYNOPSIS
irsend [options] DIRECTIVE REMOTE CODE [CODE...] DESCRIPTION
Asks the lircd daemon to send one or more CIR (Consumer Infra-Red) commands. This is intended for remote control of electronic devices such as TV boxes, HiFi sets, etc. DIRECTIVE can be: SEND_ONCE - send CODE [CODE ...] once SEND_START - start repeating CODE SEND_STOP - stop repeating CODE LIST - list configured remote items SET_TRANSMITTERS - set transmitters NUM [NUM ...] SIMULATE - simulate IR event REMOTE is the name of a remote, as described in the lircd configuration file. CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file. NUM is the transmitter number of the hardware device. For the LIST DIRECTIVE, REMOTE and/or CODE can be empty: LIST "" "" - list all configured remote names LIST REMOTE "" - list all codes of REMOTE LIST REMOTE CODE - list only CODE of REMOTE The SIMULATE command only works if it has been explicitly enabled in lircd. -h --help display usage summary -v --version display version -d --device use given lircd socket [/var/run/lirc/lircd] -a --address=host[:port] connect to lircd at this address -# --count=n send command n times EXAMPLES

/etc/lirc/lircd.conf Default lircd configuration file. It should contain all the remotes, their infra-red codes and the corresponding timing and wave- form details. DIAGNOSTICS
If lircd is not running (or /var/run/lirc/lircd lacks write permissions) irsend aborts with the following diagnostics: "irsend: could not connect to socket" "irsend: Connection refused" (or "Permission denied"). SEE ALSO
The documentation for lirc is maintained as html pages. They are located under html/ in the documentation directory. lircd(8), mode2(1), smode2(1), xmode2(1), irrecord(1), irw(1), http://www.lirc.org. irsend 0.8.7pre1 May 2010 IRSEND(1)
