Programming :: Script To Copy Paste Text From One File To Another (overwriting Part Of The File)?
Apr 19, 2011
I have a .txt-file with ~50.000 lines of numbers, generated by a mathematics program. From this file, I need line ~ 1.100 to line ~16.000 (these lines are always the same btw, this may make the solution easier, dunno) to be copy/pasted to another file, where the lines ~500 to ~15.000 (also, every time the same) should be overwritten by the aforementioned lines...I haven't found or come up with anything that works yet, mostly I find solutions to copy everything from one file to another but I can't find something to specifically overwrite a part of a file with part of another.
I'm facing difficulty while writing to an already existing file . I'm making a shell (programming in C). I want a file (say , logfile) to keep a record of all the commands a user enters. For the first command it runs fine , but for the second time and thereafter it overwrites the previous contents. How do I avoid this?
Has anyone seen a seamless way to create a symbolic link via a GUI based file manager? I have been using PCManfm because I find it fast, but I can copy the file but paste a symbolic link instead of the actual file.
I'm running and XP virtual machine using KVM / QEMU. THere are time when I need to copy text from an application in the Fedora host machine and paste the text into a different app in the XP guest machine. I was able to do this using Vitualbox on an earlier version of Fedora.
since some days I have a strange problem with KMail (1.13.5) in KDE4.5.5. When I try to copy some text from an email and past it to any other program (e.g. Openoffice), not only the marked text will be pasted, but a kind of HTML code including the text.
This bug is not OpenSuse specific. I found the same bug in a Fedora mailing list (of course, whithout an answer): Strange Copy/Paste behavior in KMail 1.13.5/Kontact 4.4.8
I want to design a kickstart file that creates an unattended installation (I've passed that part). After it installs, I want it to automatically read the device's MAC address and change the hostname to match the MAC address with the separators removed. (For example if the MAC address is 01-02-03-04-05-06, the prompt after login should read "root@010203040506")
I know this is entered in the "%post" section of the kickstart file, and I know I'm supposed to use the "cut" and "sed" commands, but I have no idea what I'm doing or how to do it. script so I can copy/paste it into my kickstart file?

I work for a company that does remote computer support, we use VNC protocol to help our clients. I installed a VNC repeater that allows my clients to connect to me going through all firewalls and port forwarding. The linux VNC repeater outputs all connection information to /var/log/vnc.log and looks something like
Code:
UltraVnc Linux Repeater version 0.14 UltraVnc Tue Mar 22 03:37:02 2011 > routeConnections(): starting select() loop, terminate with ctrl+c UltraVnc Tue Mar 22 03:37:12 2011 > acceptConnection(): connection accepted ok from ip: 55.555.555.55
[code].....
I need a script that reads this log file every so often (30 seconds to 5 minutes) and sends an email when an connection has been accepted. I looked into reading log files and got this so far
Code:
LOG=/var/adm/sqllog while true do tail -100 $LOG | grep "ORA" > /dev/null

I need to insert 3-4 lines of text to the beginning of a text file. The file is a largish MYSQL dump, the result of a backup shell script. This shell script should insert the required text.I've wrestled with sed, but lost.
I have to delete a certain line of text from the a textfile via ubuntu's shell scripting.I have done research, and it seems that most people advocate the usage of sed /d option. sed makes does not edit the text file. Hence, most options I discovered involved the use of a temporary variable/textfile and then overwriting the old file with the temporary new file. Is there anyway whereby I can bypass the use of temporary storage containers? I hope there is any magical combination of commands to edit the file directly.

I want to display the contents of a particular log file (simple text file, I mean in Linux). But there is a problem: The contents need to be organized in a fixed format. Have a look at this log file:
So, while displaying the contents of above file on a web page, I want to format the field names found in the log file: User Name:, Reported Problems Description:, and Remarks:. These fields may contain a variable length of text and no specific line number is assumed for them to appear on.
Well, what I am trying to do may sound wierd to some of you. The filed "Reported Problems Description:" can possible contain text which embeds colon (.
