Finding an email address
Hi all,
I have a file with X number of lines.
Somewhere within each line will be an email address following the format:
<telephone_number>@domain.net
Each line is not a set length and there are no delimiters to work with.
I want to write a script that extracts the telephone number from each line and writes this extract to a file.
I think the key to this is the '@' symbol, but i've had no luck constructing an awk command to extract the string (either 10 or 11 integers in length as per UK format) from immediatley before the @.
Can anyone help?
All assistance is much appreciated.
Kind Regards

xdg-email
XDG-EMAIL(1) xdg-email Manual XDG-EMAIL(1)
NAME
xdg-email - command line tool for sending mail using the user's preferred e-mail composer
SYNOPSIS
xdg-email [--utf8] [--cc address] [--bcc address] [--subject text] [--body text] [--attach file] [mailto-uri | address(es)]
xdg-email {--help | --manual | --version}
DESCRIPTION
xdg-email opens the user's preferred e-mail composer in order to send a mail to address(es) or mailto-uri. RFC2368 defines mailto: URIs.
xdg-email limits support to, cc, subject and body fields in mailto-uri, all other fields are silently ignored. address(es) must follow the
syntax of RFC822. Multiple addresses may be provided as separate arguments.
All information provided on the command line is used to prefill corresponding fields in the user's e-mail composer. The user will have the
opportunity to change any of this information before actually sending the e-mail.
xdg-email is for use inside a desktop session only. It is not recommended to use xdg-email as root.
See http://portland.freedesktop.org/wiki/EmailConfig for information on how the user can change the e-mail composer that is used.
OPTIONS
--utf8
Indicates that all command line options that follow are in utf8. Without this option, command line options are expected to be encoded
according to locale. If the locale already specifies utf8 this option has no effect. This option does not affect mailto URIs that are
passed on the command line.
--cc address
Specify a recipient to be copied on the e-mail.
--bcc address
Specify a recipient to be blindly copied on the e-mail.
--subject text
Specify a subject for the e-mail.
--body text
Specify a body for the e-mail. Since the user will be able to make changes before actually sending the e-mail, this can be used to
provide the user with a template for the e-mail. text may contain linebreaks.
--attach file
Specify an attachment for the e-mail. file must point to an existing file.
Some e-mail applications require the file to remain present after xdg-email returns.
--help
Show command synopsis.
--manual
Show this manual page.
--version
Show the xdg-utils version information.
ENVIRONMENT VARIABLES
xdg-email honours the following environment variables:
XDG_UTILS_DEBUG_LEVEL
Setting this environment variable to a non-zero numerical value makes xdg-email do more verbose reporting on stderr. Setting a higher
value increases the verbosity.
EXIT CODES
An exit code of 0 indicates success while a non-zero exit code indicates failure. The following failure codes can be returned:
1
Error in command line syntax.
2
One of the files passed on the command line did not exist.
3
A required tool could not be found.
4
The action failed.
5
No permission to read one of the files passed on the command line.
CONFIGURATION
