Given a csv file with 40 columns with name, address, hometown etc.
I use a bash command in 1 line which:
1. gets the address column and pipes that to
2. grep the first digit and everything that follows
Command:
It generates the results I want, except in the case that the grep result is empty.
When there is no digit present, the command prints nothing and the result will end up with 1 line less. That gives a problem in further processing. I need the same number of lines as in the original file. So in that case I'd like to insert a new line for further processing.
And the code needs to be in one line
I found that when I used a variable to receive the result from a command execution, the newline characters were removed from the variable.
For example, I ran
$ ret=`ls -l`
$ echo $ret
Then, I saw:

I have successfully used regexp and sed to insert a newline before or after a line containing a matched pattern /WORD/. However, I want to insert a newline immediately following /WORD/ and not after the -line- containing the pattern matched. I can match a pattern, but it is matched via a wild card... (2 Replies)

Hi,
I use sed to insert text at beginning of a file. But sed inserts a newline after my text that I do not need. For example, I want to insert "foo" at the beginning of my file:
> cat myfile
This is first line.
> sed -i '1i\foo' myfile
> cat myfile
foo
This is first line.

Hi
While trying to do a search on solaris, the grep results seems to be appearing on the same line instead of the new line.

dpkg-www
DPKG-WWW(1) General Commands Manual DPKG-WWW(1)NAME
dpkg-www - program to remotely open a WWW Debian package browser
SYNOPSIS
dpkg-www [-s|--stdout] [-h|--host host] [query]
DESCRIPTION
dpkg-www is used to remotely control a WEB browser and open a dpkg URL on the local host from an interactive shell or script.
If the command is invoked while running under X-window the script will try to find an installed X browser to open the specified URL. If
not running under X it will try to use a text browser instead.
If Netscape is found and a Netscape instance is already running it will be asked to open the dpkg URL on localhost with the optional query
supplied on the command line. If there is no browser running, it will start automatically a new one.
The functionality provided by this program is identical to running a web browser with the -remote openURL(http://localhost/cgi-bin/dpkg)
argument or opening the same URL from within the browser.
dpkg-www-installer is an helper application which can configured in the WWW browser for web installation. It should never be invoked
directly by the user.
OPTIONS -s, --stdout
Redirect output to stdout. Requires one of the text browsers (lynx, lynx-ssl or links) installed.
-h, --host host
Send the query to a remote host, where dpkg-www must be installed.
query Specifies an optional package name, an absolute pathname or a query argument which is passed to the dpkg cgi-bin. See dpkg-www(8)
for more information about the use of the cgi.
FILES
/etc/dpkg-www.conf
~/.dpkg-www
Configuration files for dpkg-www. It is not necessary for these files to exist, there are sensible defaults for everything, but you
can specify your preferred www browser with the DPKG_WWW_BROWSER variable, for example: DPKG_WWW_BROWSER=mozilla
EXAMPLES
dpkg-www
This would open a dpkg URL on localhost listing all the installed packages.
dpkg-www bash
This would open a dpkg URL asking info on the bash package.
dpkg-www -h pisolo bash
This would open a dpkg URL asking info on the bash package on host pisolo.
dpkg-www 'dpkg*'
This would open a dpkg URL listing all packages matching dpkg*.
dpkg-www /bin/bash
This would open a dpkg URL asking info on the package(s) owning the file /bin/bash .
dpkg-www depends=svgalib
This would open a dpkg URL listing all packages depending on svgalib.
dpkg-www --stdout depends=awk | grep ^ii
This would list on stdout all packages depending on awk and grep all lines of installed packages.
