Programming :: Extract A Substring Using Regular Expression With SED

May 7, 2011

I've spent most of the evening browsing the web, trying many things I've found on various forums, but nothing seems to work.

I have a test.txt file containing many lines like the following ones :

...
<insert_random_text>228.00 €<insert_more_random_text>
<insert_random_text>17.50 €<insert_more_random_text>
<insert_random_text>1238.13 €<insert_more_random_text>
...

And I want to extract :

...
228.00
17.50
1238.13
...

There is always one occurrence of € in each line. I want the numeric value that precedes this € occurrence. The random text (before and after) may contain numbers too, so the € may be important to parse, in order to correctly identify the number to return. The last character that precedes the number to extract is always a ">" (coming from an HTML tag).

Programming :: Find A Substring/member In A String/array Using Bash?

Oct 13, 2010

This may be a basic bash array/string operation related question, but I couldn't find any direct answer. So here it goes:I have a lot of data sorted in various directories. All directories need same processing except for a special group of directories. I have a symbolic link of the script in discussion in each directory. I want the script to get the name of the current directory, check if that belongs to special group and do specific operations.So I get the name of the directory

Code:
mm=`basename `pwd``
Now the the group of directories that needs something different to be done, contains these

Ubuntu Networking :: Network Manager Replaces Default Route When Eth Cable Plugged

May 5, 2010

I have been encountering this problem, not only on 10.4, but on older versions too: I use a wifi router to connect my laptop to the Internet, but sometimes I need to connect directly to another computer to move some files over GLAN. But Ubuntu's Network manager doesn't allow me to configure the eth0 interface without specifying a gateway (no gateway = grey submit button), but when a gateway is specified, it always rewrites the default gw specified already by the active wifi connection and returns back after unplugging the eth cable.

Of course this can be solved by a few route commands, but this is unacceptable since it is needed to establish the cable connection without any further assistance from within and as well without replacing the default gw and thus breaking the Internet connection. Is there, please, any possibility how to prevent Network Manager from replacing these routes?

Programming :: Effect Of Using Eval To Execute A Command As Opposed To Writing It On The Command-line?

Jun 18, 2010

Code: cmd='date | wc'

$cmd If this script is executed, an error is generated. The reason written was that "The execution fails because the pipe is not expanded and is passed to date as an argument".What is meant by expansion of pipe. When we execute date | wc on the command line, it goes fine.then | is not treated as an argument. Why?

Programming :: Command Line Invocation Of Gnome-terminal To Run More Than One Command?

Feb 16, 2010

I am trying to learn how to pass more than a one-command startup for gnome-terminal.

I will give an example of what I'm trying to do here:

Code:
#! /bin/bash
#
#TODO write this for gnome and xterm
USAGE="
${0##*/} [-x] [-g]
code....

However, running with the -g option to invoke gnome-terminal, I get a "There was an error creating the child process for this terminal" error.

This same error occurs if the gnome-terminal line is changed to

Code:
gnome-terminal -e mcTerm

Is there any way to pass more than one command on to gnome-terminal? I have tried various single and double quoting senarios and in a final attempt, I abstracted to an exported function all to no avail. Perhaps even though gnome-term is better at many things than xterm, xterm trumps it in this instance.
