I am trying to use sed command to repalce one string with other but somehow replacement string contains forwards slash hence getting the error statement garbled!
[Code]...
i want to replace
Code: <trus.analytics.platform.model.version>2.0.0-SNAPSHOT</trus.analytics.platform.model.version> with
Code: <trus.analytics.platform.model.version>2.0.0-b-20</trus.analytics.platform.model.version> using sed command. Code: sed -i

I think there is a problem with front-slash but not sure how to resolve it.

Does it possible to escape * in the case statement
Code:
We are building our C++ project in Kdevelop IDE. Every time we run "Run Configure" from the "Build" menu, a file named "libtool" gets automatically generated. This file contains a statement as "ECHO="echo"".f we run "Automake", without modifying the "libtool" the system hangs and theputer needs to be restarted.Therefore every time we run "Run Configure" we need to include the line "echo="echo"" below the statement "ECHO="echo"" manually.I think a script can be written which does the above on its own.I am not a shell script programmer, I know the good tutorials for shell scripts are available on the net, but learning scripting only for this task would be time-consuming and painful.

I run slackware 13.0 with firefox 3.5.2. The sound works great for the most part. But sometimes after the browser has been open for more than a few hours, and after a few hulu and ..... visits, I start up another movie and the sound is all jarbled and echoy. So I just 'pkill firefox' Run firefox and restore the sessions and everything is back to normal. Seems like it's just a firefox bug.
View 2 Replies View RelatedRunning exim4 on debian and trying to forward all emails destined for root@mydomain.com to me@mydomain.com, I did setup the entry in the /etc/alias file in the following way:
root: me@mydomain.com
run newaliases restart exim "although not needed if I am not mistaken"
then on command line mail root@mydomain.com and the email still goes out for root@Mydomain.com and not me@mydomain.com I am using a smarthost, and that smarthost refuses to serve emails going for root@. I am OK with that as I should be able to easily rewrite those message to go to me@mydomain.com
But it is simply not working, anything I might have missed here ?
I play a flash video, and then play music natively the sound doesn't work. Or I can play flash and have sound but not play music with sound that's on my PC. Or I play my music on my PC, say one song, and the other is high pitched distorted, and rings. I have to exit the program and start it again for it to play nice. How do I resolve this most irritating bug?

sometimes there are one, sometime there are two exchanges in this log file. the 100= is the stock exchange- if there are two, they are seperated by a comma. i understand how to escape a comma in a regex, but I am having trouble with combining it.

I need to occasionally touch a file with the current timestamp as the filename. I would do so this way:
touch `date "+%Y-%m-%d_%H-%M"`.txt
However, I'd like to define an alias for this. When I try adding to the bashrc this:
alias td="touch `date "+%Y-%m-%d_%H-%M"`.txt"
the result is that the filename is the same during the entire session, since the `date ..` gets calculated just once during login...
How can I get the command to expand only when I call the alias? Or must I use a function for this?
Usually when I need to replace some lines in a file, the first tool that comes to mind is sed -i:
sed -i 's|tool:.*|tool: some-tool|'
However, it's inconvenient when there are . characters in the replacement string:
sed -i 's|host:.*|host: 127.0.0.1|' Is there a better tool for this case?
Need little advice running this command.
watch -d 'ps aux | awk '{print $4" "$11}' | sort | uniq -c | awk '{print $2" "$1" "$3}' | sort -nr | head'
I get this error message from AWK. awk: cmd. line:1:

I have tried all the usual by trying to escape the single and double quotes in the command but same result. The end result should be the a listing of memory hungry processes that are scanned every 2 seconds (watch default value).

I am "fleshing out" my USB flash drive Netbook Remix of Ubuntu and have run into a snag on getting Mplayer Movie Encoder to work. Synaptics eventually showed 28 new packages will be installed which was done. But, the skin showing the "controls" (fast forward, pause etc) is dead. I am using the USB flash on a HP desktop and all other Remix features work well. Plus the Nvidea gui card fills my 19" flat screen exquisitely well. And, the stick works very nicely on my Acer Netbook (aspire one 250) too.

I came to debian from fedora so there I used ( su - ) to become root user. So my question is that in debian, is it same using ( su ) and ( su - ) or here also using ( su - ) is preferred with slash or without slash. What is the correct and secure way in debian with full root status.
One more question relating gedit sources.list
I use as root account : gedit /etc/apt/sources.list (and then enter and sources file in gedit open)
Is this correct method or any other way as when save after changing entries inside it says error.

Fedora 14
When I started I took the defaults and ended up with Evolution.
I have never managed to get it set up to send. It and godaddy are on diffferent planets.
Having used Thunderbird in the past, I downloaded it and it automagically set itself up to send and receive.
So now I use Thunderbird - BUT - when I click on a link in an html page - the mailto macro sends me to something other than THunderbird - perhaps Evolution - and nothing gets sent.
So how do I tell the system that when i click a mailto in firefox I want Thunderbird?
PS I think I found it. In firefox - edit - preferences - applications tab - mmailto - it said Evolution. I changed it so say /usr/bin/thunderbird - will now test it.
YES - Seems that asking a question triggers my brain on how to resolve it. Sorry to waste your time.
I wish to replace a new line with br (html) but it doesn't seem to work
Code:

I'm a bit stuck with IF statement. There is the code:
#!/bin/bash
# Variables
VAR1=test
VAR2="echo $VAR1"
# Case 1
echo Case 1
if [ test == test ]; then
echo "equal"
else
echo "not equal"
fi;
echo ""
# Case 2
echo Case 2
if [ "VAR1" == test ]; then
echo "equal"
else
echo "not equal"
fi;
echo ""
# Case 3
echo Case 3
if [ "VAR2" == test ]; then
echo "equal"
else
echo "not equal"
fi;
echo ""
When executed, why case "2" and "3" differs from case "1"? Where am I wrong and how to solve this trouble? (my aim is to get "equal" from all cases).
I want to have the System Bell ring when a process is over say a download. First I created a file named 'beep' that plays the System Bell. Because the System Bell rings by hitting cntrl-G the 'beep' file looks like this.
Code:
echo ^G
I then give the file owner execute permission. I know that this command would serve my purpose.
Code:
[URL]
However I want to sharpen my Bash programming skills. I wanted to write the Bash script along the following logic and with the fewest lines possible. Not really a script, I want to insert this short script via command line instead of a file. Let's say the download has commenced and the PID = 16666.
Code:
until ps -p 16666
do
/root/beep
done
Now obviously 'ps -p 16666' will already evaluate to true. My question is, is there a way to maybe enclose 'ps -p 16666' and prepend some operator that inverts the condition to where until 'ps -p 16666' evaluates to false then run /root/beep?
I need to to write a bash script using an If...Then...Else statement that will accept a day of the week from the command line what do I do or where do I go.
