General :: Replace Multiple Instances From X To Y In Line
Feb 1, 2010
I have a line of text with multiple web links in the line. I'd like to replace the actual links with the text "<web-link>" so I don't accidentally hit them while reading on my iphone. I've tried many versions of the following sed command, sed 's/(http.*)/<web_link>/g', but it simply replaces everything between the first instance of "(http" and the last instance of ")" with <web_link>, or does nothing at all.
Ex: This line has a link to a web page (http://www.webpage.com/file.html) then some more text (extra text) and then another link (http://www.nextwebpage.com.index.html) to a website.
$ echo "This line has a link to a web page (http://www.webpage.com/file.html) then some more text (extra text) and then another link (http://www.nextwebpage.com.index.html) to a website." | sed 's/(http.*)/<web_link>/g'
What I get is: This line has a link to a web page <web_link> to a website.
What I'd like is: This line has a link to a web page <web_link> then some more text (extra text) and then another link <web_link> to a website.
What am I doing wrong with my sed command?
:0 local /usr/X11R6/bin/X -nobanner :1 local /usr/X11R6/bin/X
I need to add "-nolisten tcp" to both of these lines and cannot figure out how to do it. I can get it to do the first one, but not the 2nd and so on. How do I search the file and loop though it to change them all?
Hello, I need some help searching through multiple files, finding a line and replacing that line. The line I am searching for is:
password key ******* 1222554
ultimately I want to be able to delete the numbers after the asterisks . my thoughts are to create a script that will search for the line password key ******* and delete it then replace it with password key ******* my files are located in /opt and they are all txt files.
I'm pretty sure this is doable from the command line, but my CLI skills have degraded a lot since my pre-Y2K admin days. The goal is to search all the files in the directory for a very long string of text and replace it with another string of text. The text being searched for is my Google Adsense code (which will be stripped from my website) and it will be replaced with a placeholder so I can easily tack something else in there in the future.
Seeing how I have that long snip of code on about 100 pages, automating the process would make life easier. If I was searching for a single word, I can see ways to do this. If I paste the code I'm searching for into a text file, is there a way to: find (contents of oldstring.txt) and replace with (contents of newstring.txt)?
In windows xp, i created another user account. Now i can run a second instance of any program by right clicking on it and selecting Run as. Is such a thing possible in linux (centos or ubuntu) in graphical environment ?
How can I have multiple independent instances of Mozilla Firefox 3.5 on the same X server, but started from different user accounts (consequently, different profiles)?
Limited success was only with Xephyr :1, DISPLAY=:1 /usr/local/bin/firefox, but Xephyr has no Cygwin/X's "rootless" mode so it's not comfortable (see other question).
The idea is to have one Firefox instance for various "Serious Business" things and the other for regular browsing with dozens of add-ons securely isolated.
On Windows If I run Firefox as user jack, and then try to start another instance of firefox I will be unable to, as one is already running.If I choose to run firefox as administrator,then I can have two instances of firefox, separate from each other side by side, because they are under different user accounts.This does not seem to be true on Linux.As user jack if I start firefox, like on windows I am unable to start a new instance.If I open a terminal and change to root, set XAUTHORITY to jacks .Xauthority and try to start firefox as root....I get the error that firefox is already running.
I need to run multiple squid instances on my server , I am running squid version squid-2.7.STABLE5-1.el4 on RHEL 4.7 , kindly tell me how to do so. by the way , I need to run two instance because i need to configure my proxy to act as a reverse proxy and a forward proxy, and people told me that you cannot run a forward and reverse proxy on the same instance.
I have to run multiple instances of apache on the same physical machine, as we have different OAM policies for different domains.is in the httpd.conf file can I have ServerName same in two instances of apache, like
ServerName: prod_machine (actual machine name)
In the vhconf files I do have different servernames for virtual hosts. Apache instances are running on same IP but different ports. I am including various vhost files in the main httpd.conf file. Can I skip servername in the main httpd.conf file and include different servernames in the virutal hosts configs. OS: Solaris10
If i have, say, ..... tab opened and if a click on some of the related videos (while it's still playing) firefox terminates. The same if I open ..... on one tab and myspace on another - firefox just shuts down.
I want to know why this happens, is it a bug and how can i fix it ?
I have multiple hard drives with videos on them and i can only get the my xbox to read the 1st in my list of directories. So i wanted to know can i run multiple instances of ushare and use one for each hard drive? Is it possible?
It is possible to run multiple instances of a jar executable. Is it possible that only a single instance of the jar runs? Wrappers like JSmooth or Launch4J can be made to run as a single instance. But since there are no such wrappers for linux, I need a way to restrict the jar to a single instance. How to embed the jar file into an executable such it runs a single instance?
i'm new to linux, and i want to create mumble servers for my friends.My first server is finished and he works but, is it possible to create multiples instances of mumble ?
I've got two sound cards fitted, before I've always killed pulseaudio as a pain in the butt.
Without pulseaudio enabled I could run two audio apps simultaneously, ie run a SDR ( software defined radio) app , and listen to music or watch TV at the same time.
However, with puls audio running, you can only run one, either input to either output. So can a second instance of pulseaudio be run, master and slave perhaps ?
The great clock applet shows tasks and appointments from the evolution calendar. That's a great and fast overview of my agenda. But clicking a task of appointment opens a new instance from evolution every time, which is enormously annoying and really destroying productivity. I don't want 15 calendars open, I want the applet to behave like an index. So it should reuse the open instance and bring focus to the clicked appointment or task. How do I disable multiple instances of evolution?
I have a test server on which I'd like to run up to 30 separate instances of a program as daemons, each running on a different IP address bound to the server. I've created a init script that takes an additional command line parameter - the last octet of the IP address. For example:
Code:
sudo myprog 40 start sudo myprog 41 start
This would run instances of the program on IP addresses 192.168.1.40 and 192.168.1.41 respectively. But it's looking like this approach isn't doable if I wish to have any or all of these run at startup, as the links in the rcN.d directories can only link to the init script, not pass a parameter.
I tried the google and browsing the known bugs in the sticky before posting this thread.On boot the machine is pegged at 100%. It is a dual-core with 4GB of ram and is running 10.04, 64bit. Also, as time goes on it eats up all the ram till theres maybe 32mb free. What happens is there are multiple 4-10+ identical processes running. seem to be gnome related.The machine sits idle on my floor and runs samba and apache/mysql/gallery for my test website that no on but myself visits.
I have enabled netbook-launcher-efl and like the interface quite a lot, but it only allows me to launch a single instance of each application. I was told in an unrelated thread that there should be a setting in gconf-editor that enables multiple instances to be launched, but I thought it would be more appropriate if I broke that out into a separate thread.
Using more than one instance of the same app is a real pita in Unity.If I have 3 (or more) pdf documents open in evince then there isn't a way to shift from one to the other using the mouse. Previously I had the windows on the taskbar and could click on the one I wanted. In Unity clicking on the evince icon on the launcher just brings ALL the instances of evince to the top - I still then have to shuffle the windows around to get the one I want.I've been trying to get used to Unity over the last few days, so maybe I am just doing it wrong, but if not then maybe I should file a bug report?
I am running a script that can run as many as 10 simultaneous times. During my testing, i noticed that if the script starts while another is in process, it inherits the $1 variable, which is always different.For example, the script starts with "scripthere.sh entry1", anther one starts almsot at the same time "scripthere.sh entry2". As the script is running, the second instance inherits $1 from the first script. So instead of $1 entry2, it shows up as entry1. how I can store $1 so that its unique to that instance of the script only?
I know that bash can suspend and resume processes, but I am interested in forking and resuming them from different bash instances. So, for example, forking a gui app started from the console so that it will not crash when the terminal is closed. I currently know about screen, which can work, but I was wondering if there was a way similar to Ctrl+Z, bg and fg.
I need to run two instances (i.e run the program twice, with two separate windows) of Audacious. This is for a play where I need to have music and sound effects going at the same time. I could do this while running Fedora 13, but after upgrading to 14 the audacious package was updated and now can't do this. My attempts at downgrading have been unsuccessful, and I need the audio done by tonight (the last rehearsal). So... am I up the river without a boat, or is there a fast solution? I'm open to anything, as long as the music player has advanced controls (play, pause, stop, fast forward, rewind, forwards track, backwards track) and can have two instances running at the same time.
I trying to change a file with hundreds of entries, replacing line with "IP Address Number" for "Host Name", one for another.
this is the original: [IP Address Configuration : "172_17_27_161.SUBNET_U"] IP Address Number = 172.17.27.161Assignment Type = 8Host Name = CAST124Last Used = 1290499294000MAC Address = 1 00 16 35 74 4C 59Client Identifier = 01 00 16 35 74 4C 59and the result desired is: [IP Address Configuration : "172_17_27_161.SUBNET_U"]Host Name = CAST124Assignment Type = 8IP Address Number = 172.17.27.161Last Used = 1290499294000MAC Address = 1 00 16 35 74 4C 59Client Identifier = 01 00 16 35 74 4C 59I know how to change one character by another with sed, but not to change a line for another, because I don't know in which line number it is.
15 for(i = 0; i < N; i++) I want to replace "i" with "test" in the line above,whose line number is 15. When I tried this command :15s/i/test/ Line 15 turned to be this: for(test = 0; i < N; i++) It only replace the first "i",but I want to change all "i" in line 15.
