I am trying to understand what the grep command in ubuntu is trying to do here.
The contents of my test file is given below
When I grep for 3 dots (...) without the parenthesis as follows I would expect the output to match the first 3 characters in the above file. But the output I am seeing shows that it matches more than 3 characters in some lines. Can anyone help me here understand why the 3rd line is being shown to match more than 3 characters.
please send the logic or program to find the matching characters between two strings
for ex string1 :abc
string2 :adc
no .of matching characters is 2(a,c) (9 Replies)
how do i check if the first character is a parenthese in pattern matching?
if ] obviously doesnt work. How do I use it to compare so it doesnt try to use it to group. (5 Replies)

0299:ffff0000:0009:01f4:2:319
02d2:ffff0000:000e:01f4:2:507
The above values are split up using ":" characters.
I would like capture each value, no matter what length.
Take for example the first line... (8 Replies)

ubuntu-dev-tools
ubuntu-dev-tools(5) File Formats Manual ubuntu-dev-tools(5)NAME
ubuntu-dev-tools - Configuration for the ubuntu-dev-tools package.
DESCRIPTION
The ubuntu-dev-tools package is similar in scope to the devscripts(1) package, providing a collection of scripts which may be of use to
Ubuntu and Debian developers or others wishing to build Debian packages.
Some of these scripts have options which may be configured on a system-wide and per-user basis. These options are configured in
devscripts.conf(5).
All variables are described in the script's manpages. Package-wide variables begin with "UBUNTUTOOLS" and are listed below.
Every script which reads the configuration files can be forced to ignore them by using the --no-conf command-line option.
ENVIRONMENT
All ubuntu-dev-tools configuration variables can be set (and overridden) by setting them in the environment (unlike devscripts).
In addition, several scripts use the following environment variables:
UBUMAIL
Overrides DEBEMAIL and DEBFULLNAME when the target is clearly Ubuntu. Can either contain an e-mail address or Full Name
<email@example.org>.
DEBEMAIL, DEBFULLNAME
As in devscripts(1).
PACKAGE-WIDE VARIABLES
The currently recognised package-wide variables are:
UBUNTUTOOLS_BUILDER
This specifies the preferred test-builder, one of pbuilder (default), sbuild, pbuilder-dist.
UBUNTUTOOLS_DEBIAN_MIRROR
The preferred Debian archive mirror. Should be of the form http://ftp.debian.org/debian (no trailing slash). If not specified, the
master will be used.
UBUNTUTOOLS_DEBSEC_MIRROR
The preferred Debian security archive mirror. Should be of the form http://security.debian.org (no trailing slash). If not speci-
fied, the master will be used.
UBUNTUTOOLS_UBUNTU_MIRROR
The preferred Ubuntu archive mirror. Should be of the form http://archive.ubuntu.com/ubuntu (no trailing slash). If not specified,
the master will be used.
UBUNTUTOOLS_UBUNTU_PORTS_MIRROR
The preferred Ubuntu archive mirror. Should be of the form http://ports.ubuntu.com (no trailing slash). If not specified, the mas-
ter will be used.
UBUNTUTOOLS_LPINSTANCE
The launchpad instance to communicate with. e.g. production (default) or staging.
UBUNTUTOOLS_MIRROR_FALLBACK
Whether or not to fall-back to the master archive mirror. This is usually the desired behaviour, as mirrors can lag the masters.
If on a private network with only a local mirror, you may want to set this to no. One of yes (default) or no.
UBUNTUTOOLS_UPDATE_BUILDER
Whether or not to update the test-builder before each test build. One of yes or no (default).
UBUNTUTOOLS_WORKDIR
The directory to use for preparing source packages etc. When unset, defaults to a directory in /tmp/ named after the script.
