I have an command to read inputs from file2 and replace the content in file1. Issue is that the op is coming in a single line as gsub and split functions don't recognize new line characters.
Code:
awk 'NR==FNR{gsub(/input./,""); split($0,a," = ");b[a[1]]=a[2];next} {gsub(/@/,"");for (i in b) gsub(i,b[i])}1' $t2 $t3
This gives belwo op:

I would like to change the formatting on my BASH prompt from this:
anon@machinename.domain.poo:~/some/very/annoying/long/path$
to something like this:
anon@machinename.domain.poo:~/some/very/annoying/long/path
$
The idea is that I would be able to type a reasonably long command on one line without it wrapping to the next line so quickly.
I'm writing a script that takes the date attribute of a file when it was created and appending it to the name. I'm pretty close to what I need, but the date appears in yyyy-mm-dd format and I want it to read mm-dd-yyyy. What I have done so far is something like
for ((i=1;i<=50;i++));
do fdate=`stat -c %y Video Snapshot $i.png|awk {'print$1'}`;
newname=Personname-$fdate-$i.png;
mv Video Snapshot $i.png $newname;
done
This works decently but the date comes out in the yyyy-mm-dd format. How do I change it?
As I recent convert from Ubuntu to Centos, I have a lot to learn. In Ubuntu, I can plug in a memory stick, run the menu option: System/Adminstration/Partition Manager, highlight the memory stick and choose "Format: Encrypt"
In Centos, my memory stick is /dev/sdc1, how do I, using command line: format it as /ext3, encrypt it using cryptsetup, and set a password?
I've been asked to move data from an old external hard drive to a new one, and to make the new one compatible with the Macintosh. (The old drive's USB connection has died, and I'm connecting to old the drive using a PC card that provieds an eSATA to the drive. The recipient's Macintosh doesn't have a PC card slot, so she can't access the old drive anymore. Hence, the new drive.)
Naturally, I'm doing this data transfer using Linux. I've discovered that I can format the drive as HFS+ using mkfs.hfsplus from the hfsprogs package. But I need to know: do I need to do anything special with the partition table? Is there a special Macintosh partition table format that I need to format this disk to? If so, what tools can I use to get the right format for the partition table?
I'm looking for a way to force my PS1 variable to a certain number of chars.
It currently looks like:
$PS1="W $"
and I'm trying to keep the same number of characters regardless of the length of current folder name.
For example, both Documents and bin would be displayed as 10 character strings, keeping the left side of my terminal the same width all of the time.
I bought a 3 TB western digital but I cannot format it. I have to split into 2TB and 1TB (or less because it holds 2.73 TB actually). Is that normal because of linux does not support 3tb yet? I note that I tried into EXT4 and JFS (after tabel creating)
View 1 Replies View RelatedI have a 4 Gb memory stick which used to have OpenSuse on it but I don't use OpenSuse and wanted to use the stick for something else - for backing up my Mozilla Thunderbird installation. I thought that by re-formatting the stick, using a file obtainable from the HP web site, in connection with installing Linux on a memory stick, that it would leave me with an empty one but it hasn't; there is still a lot of OpenSuse stuff on it. How can I "empty" it so that I can use it to transfer my Ubuntu Thunderbird to another computer which is also running Ubuntu. I was going to open a terminal and type:
sudo cp -avr /home/chris/.thunderbird/ /media/disk
I have already tried this but it didn't appear to work, so is this not the right way to go about it?
I have created one partition. Now I want to extend that partition without formatting it.

I have only known about Linux software for the past couple of weeks. I want to install Ubuntu 10.10 on an older desktop I have so I can become more familiar with it. I am average in knowladge about Windows OS and MS-DOS. I tried to install Ubuntu and I get an error message about the harddrive. The CD I am booting with will load on my other PC with Windows XP on it. I have only let it run on it long enough to verify that it is bootable.
I have made a floppy boot disc following the instructions on another Linux site about Ubuntu. I have also tried to boot my alternate PC with the floppy and it boots up. The harddrive on my working PC is a Maxtor 40gb formatted with NTFS file system. The harddrive in the older desktop is a Western Digital 80GB WD800LB-55DNA0.It worked fine with Windows XP on it. I also made a Western Digital DATA Lifeguard for DOS floppy and it boots with it.
I don't want sympathy, but merely explain what I'm up against. I'm 63 years old. I'm on medical and mental disability (Cognitive failure, the beginning of Alzheimer's). I used to be a good computer tech, but now, because of my memory problems, I don't remember how to do a lot of things with a computer.I'm seeking assistance (not 24/7 help or hand-holding)to help me reformat,partition, and set-up a dual-boot for both WIN 2000 Pro and Ubuntu Linux to operate programs where I can use my Amateur (Ham) Radio in digital modes (PSK-31, PSK-64, BPSK, cw, etc). I'm choosing NOT to run Ham Radio DeLuxe, as it's bloated with M$ "code" and could be hacked and messed with.
The hard drive is a Maxtor 80 gig (78 g formatted). I have another drive,a Western Digital 40 gig (37 g formatted) that I use for Windows as well, but mostly it contains Excel spreadsheets with Part 90 - Public Safety frequency information for the local (within 250 miles) from my home. It's a FAT 32 and I'd like the 80 gig to match that
How can I change the label of one partition on linux without formatting it.
It wll format the partition, and all content disappears.
I'm writing a script that gives me some pertinent info about my servers, and the last little piece I need to figure out is the process list. There are going to be non-technical people looking at the output of the script and I'm trying to make it as simple as possible.
Right now, if I do ps -ef | grep <process> | grep -v grep
It obviously shows me the process, but the problem is that there is 4 lines of info in front of the process. ie
root PID date time java -1024 -cp oh,my,god,there,is,so,much,data,it,carries,on,for,4,lines,I,want,to,shoot,myself,trying,to,read,it,f inally,in,the,end,there,is,a,space /here/is/the/process
I'd like the output to be something like this:
PID: #### Process: /here/is/the/process
I've thought about how I could take the output and use awk or sed but I know there is probably an easier way to do it with perl.
I have a 16GB memorystick which used to have a Linux partition. It therefore has two partitions; 2GB FAT32 and 14GB linux boot drive. The linux part stopped working, so I decided to reinstall it. But windows can't see that partition. I tried formatting the whole disk, but I can only format one partition (the FAT32). There seems to be no way to combine the two partitions into one big one, and there seems to be no way for windows to partition the large part of the memorystick to but Linux on it. In the windows partition manager, windows sees the large unused partition, and it let me delete it. But once I have deleted it, I'm not allowed to format it. Also I cannot delete or resize the small partition. I have a memorystick with two partitons. Windows only sees one of them, and won't let me use the other one. I would like to combine the two partitions so I can install Linux on the memory stick again.

I'm a big fan of the NSLU2-Linux project so I've been doing some developments for this platform for the last three years. In order for the end users to test my applications, I initially created an USB image with everything bundled into it. Then, they only had to download the image and decompress (dd) it into an USB pendrive with capacity equal or greater than 4 GB. The fact is that this has brought me lots of problems in the practice since my Web server hardly accepts long file transfers.
Moreover, flash spaces beyond 4GB are wasted. As result, I'm now considering a different approach as I don't know how to do it. Well, I've thought that I could maybe create an USB disk image only with the root file system partition. Then, the first time a script runs, it creates a home partition and formats it into the rest of the space available in the pendrive. There is maybe some command-line alternative to fdisk without having the user to interact during the format process... ??
I have a computer that was given to me and is no longer booting up properly. It's an Acer with VISTA installed. I would like to format the hard drive and start over with Linux. I don't have the original windows vista disk, I don't believe the computer even came with one, and no back up disks. Apparently this is the only way to format VISTA. When I am in the command prompt here is what happens.
C:> format c:
The type of the file system is NTFS.
Enter correct volume lable for drive C:
I don't know the correct label.
Searching on the forums I found this.
format c:/fs:NTFS/p:/
That doesn't work. I get this:
"Invalid parameter - /p:"
How can I format a USB hard drive to ext3/ext4 or whatever file format and have full permission to read, write and execute all files afterwards? When using the command line (as ROOT of course) mkfs.ext3 /dev/sdb? Restricts the rights to ROOT as does the procedure gParted. The man mkfs did not help much. Configuring the fstab- file is a bit of a hassle, so it would be nice, if there was an option to set the permissions "correctly" right from the beginning. Setting Ubuntu (I'm using Ubuntu 9.10) up, so that it mounts USB devices not as ROOT as default but giving all users all permissions seems to be really complicated, as a guy from my local LUG told me.

I have a question about viewing HTML emails in the Evolution mail client. Basically, I am receiving some emails that look lovely in Thunderbird but not in Evolution because the HTML rendering of Evolution isn't as advanced.Here is a screenshot of the difference: how to improve the HTML rendering of Evolution? e.g. a plugin, tip, code patch, etc. The closest I've got is to right-click the email, "Save As...", save as a html file, then open in Firefox. Not exactly streamline!What emails can't it display well? We use the subversion revision control system which is set up to send an email whenever someone commits via svnnotify all nicely coloured via the --handler HTML::ColorDiff -d parameter. When Evolution fails to use the colours, I find it very hard to read the raw diff.
View 1 Replies View RelatedI have a server running an older version of Ubuntu and with /var stored on a separate partition on a separate hard drive.
