The ide has xp and I installed debian on the sata, the duel boot worked fine and still does. I then installed unbuntu on the sata along with debian but can't access unbuntu. when I tryed to install grub it error'd out so I bypassed that and finished the install. It told me I would need to pass a kernel argument to load ubuntu but I'm clueless about what that means.

when I am running the script below,it performs on whatever logfile u type ,i.e, ./scriptname logfilename.But how do I convert it into a function and then call it from another script.I mean how do I prompt the user to enter a logname and then capture the name in the function and when calling this function from another script how do I pass the parameter.
View 3 Replies View RelatedI am attempting to script some tasks I have to do, but I have no control over one of the scripts I have to use... and they output all kinds of useless things on the screen. My goal is simple: Capture all output from their scripts, and create a progress line that only shows the most recent output from their stuff. So, here was my first solution; a file I called "spin":
Code:
#!/bin/bash
spinX(){
PROC=$1
STRT='date "+%s"'
while [ -d /proc/$PROC ];do
last3=" 'getLine $2' "
To use it, you pass it a process ID and a file that contains the output from that process. As the process continues, a kurby dances on the screen (To let you know that the process has not hanged), and the tail of the output is shown (To let you know what it is doing). When the process ends, the kurby stops dancing and the time it took is displayed.
And here is the file I call "noise":
Code:
#!/bin/bash
while [ i -lt 100 ];do
i=1
echo "Look at me count!$"
sleep 1
let "i=$i+1"
done
This does nothing but create random output, for testing. It counts from 1 to 99 on the screen. To run my test, I do the following:
Code:
(noise) &>tmp.txt & spin $! tmp.txt
It works relatively well, but it is messy. I don't like creating a temp file, and I don't like the messy syntax for calling my program. I decided that I would rather move everything into the spin program, to make using it less messy:
Code:
#Spin Psuedo code
#$1 = command I am about to run
(exec $1) &>tmp.txt & spinX $! tmp.txt
By executing the process inside of the spin code, I can get rid of the tmp file later on without changing a lot of scripts (Or move it, or whatever). I can also call it by passing the command to the script, which I find more elegant.
So here is what I would like to know:
1) If possible, I would love to get rid of the tmp file all together, and store the most recent line of output from script 1 into a variable that script 2 can print out instead... is it possible?
2) How can I run a random command that is passed as an argument? Basic ones work fine, but anything with a pipe fails me.
Example of a script:
Code:
#!/bin/bash
#myEcho.sh
echo;echo "Recieved command: ";echo $1;echo;
echo "Attempting to run command: ";echo
exec $1
Example code for passing commands to script:
> myEcho.sh "ls -al" #works
> myEcho.sh 'ls -al' #works
> myEcho.sh "ls -al|grep *.sh" #fail
# Output:
#ls: invalid option -- |
#Try 'ls --help' for more information.
> myEcho.sh "ls -al|grep "*.sh"" #fail
# Output:
#ls: invalid option -- |
#Try ls --help' for more information.
> myEcho.sh 'ls -al|grep *.sh' #fail
# Output:
#ls: invalid option -- |
#Try 'ls --help' for more information.
I want to have a choice or more preferable pass shell as command line argument when I ssh to an linux account.i.e. If John logs in to account "zzz" on server "abc", by default definition of account "zzz" n server "abc" he get csh.But Sally desires that when she logs in to account "zzz" on server "abc", she needs the login shell to be ksh,and Rick wants bash when he logs in to account "zzz" on server "abc".What is the most non-intrusive / easiest way to achieve this? Each user can set their preference on ssh command line or create a simple alias by each shell, but not sure how to do this.

I'm trying to write a base script which will divide an argument by 10 and then use that argument in another program. Since my argument can be a floating point number, I used bc to accomplish this. Here's an example of a simplified version of what I have so far:

I installed ubuntu on a second hard drive.Nowhere did the fracken ubuntu installer ask my permission to over-write my mbr but that's exactly what it did.I'm booted off the rescue CD trying to restore the mbr to how centos left it (I'll add ubuntu to grub manually) but I can't boot into rescue.linux rescue results in a kernel panic suggesting I need the noapic argument. Makes sense, I needed that to install and need that in grub.linux rescue noapic boots into the installer, not rescue.How do I boot into rescue mode with the noapic kernel argument?

View 5 Replies View RelatedI have installed Linux Mint 9 within Win XP and have installed an additional HDD as a Slave on the same IDE cable as my DVD drive. I installed ubuntu on to the additional HDD using the live CD and when I try to boot the computer I am greeted by two versions of GRUB?! First version appears to be the one that comes with Mint and so asks me to boot either Windows or Mint, when I select Mint I get ubuntu's version of Grub, it asks me to boot one of three OS's; here's where it gets weird:
Top of screen says:
GNU GRUB Version 1.98-1ubuntu5-1mint2
If I select Win, it boots fine. If I select Mint it boots fine however if I select Ubuntu it says:
error: no such device
error: file not found

I pressed "e" within grub and was faced with this:
insmod ntfs
set root ='(hd1,1)'
search --no floppy --fs-uuid --set f6422203421e479

setroot =(loop0)
linux /boot/vmlinuz-2.6.3-21-generic root =dev/sdb1 loop=/linuxmint/disks/root.disk ro quiet splash
initrd/boot/initrd.img-2.6.32-21-generic
I unfortunately remove "some" softwares on my OpenSuse10 (preinstalled on my laptop, without cd driver) cause I was running out of space on hd. Icons starts to dissappear ...
Then I have only the Grub 0.97 shell that appears and to use to solve the problem... tried to boot kernel, but said that it "must be loaded before boot".
In the Grub 0.97 black window I have two lines :
I press "b", to boot with the First line : kernel (hd0,2)/boot/vmlinuz ... but the window turns blue and said "all data would be lost", so it shut down the system automatically to avoid this.
I press "e" to edit the command in the boot sequence for the same line, but don't really know what to tell Grub to do.
I must get my important datas back on my hd before "Restore to factory settings" (the last option). Any solution ?
Maybe it is a step on a solution ?
From [url] I downloaded linux kernel 2.6.27.27 on a usb memory stick. Could it be useful ? how to ?
I have a loadable module, simple enough I believe it should run on any 2.6 kernel. I want to force the load and test that assumption. How can I do it?
ismod does not seem to notice the -f in 2.7 modprobe has -f but cannot locate the module.No go. So I read the manpage for modprobe which says: modprobe looks in the module directory /lib/modules/'uname -r'.So I copied MYMODULE.ko to /lib/modules/2.6.(the only directory in here) and type: modprobe -f MYMODULE.ko.Still can't locate MYMODULE.ko.I notice there are no other .ko modules in that directory; so I go in deeper to kernel/drivers/char, guessing about the char directory, and copy MYMODULE.ko there.
I updated the Ubuntu version 10.04.1. After updating the program it tells to restart the system. After restarting the system the following message appears:
error: can not read the linux header
error: you need to load the kernel first
Over the past few days I have been trying to install an older kernel (kernel 2.6.28.1) on ubuntu 9.10 64-bit WUBI installation. I compiled, installed, and updated my grub for the kernel. When I reboot, the grub menu correctly gives me the option of booting into the older kernel but when I do so I receive the following error message:
error: you need to load the linux kernel first.
I am at a complete loss on how to fix this. I even downgraded grub but I still get the same error.
In 10.04 I was using the following commands to mount an encrypted disk image:
Code: sudo losetup -f Which tells what loop back device block is available Then I'd type:
Code: sudo losetup -e aes /dev/loop0 /home/user/crypt.img and then enter the device's password
Code: sudo mount -t ext4 /dev/loop0 /media/crypt I've tried this in 10.10 and it hasn't been working (I can't remember if I did anything in 10.04 to make it work). I've installed the loop-aes-utils package and restarted my machine. Every time I try the 2nd step, after entering the password I get: Code: ioctl: LOOP_SET_STATUS: Invalid argument, requested cipher or key length (128 bits) not supported by kernel
I am an experienced Linux admin and have been using SuSE for many years. My development machine has had every version of SuSE since '02 and although it is a little old, is in good working order. (AMD
2400, 2 gig RAM, 160 Gig IDE disks - SuSE on disk 2) (OpenSuSE 11.1 with the latest kernel works perfectly. This install is on a spare HDD prior to doing a full install on my usual HDD.)
When I try to install SuSE 11.2 from DVD, the load kernel operation hangs at 97% (using both normal and safe kernel), however, I can install from live CD without any problem. I have tried the same DVD on a few "older" machines and had the same problem. I initially thought it was the actual DVD but re-burning has the same problem. I have also tried another DVD writer - same problem.
I installed bt4 alongside my windows and fedora13 partition, but my fedora won't boot after that, so I updated grub to 1.96, but still fedora13 won't boot, it displays the error, "You need to load the kernel first". When I try to boot fedora from grub command line, linux (hd0,6)/boot/<TAB> it does not show any entry, although my fedora partition is intact with vmlinuz and initramfs inside the /boot directory. BTW (hd0,6) is my fedora13 partition, file system on fedora13 is ext4, while on bt4 it is ext3.

I went to fire up Lucid this after noon and it gave me this error message. I didn't want to write all of that down so I took a picture. After several minutes it did nothing. I then decided to do a hard restart. This time it isn't giving a signal to the monitor. The monitor is less than half a year old, but I tried another. Still nothing. It show's no signal like it's not even hooked up to a machine. It doesn't even show the BIOS menu! I don't know if this is the cause or not but, I left my computer at my mothers house last night were they had a thunderstorm.

I have windows xp and now I have installed UBUNTU 9.10. When my laptop starts it comes up with the option of Windows Xp and Ubuntu. Selecting windows xp works fine here but Selecting UBUNTU comes up with another screen giving three options.
1. UBUNTU
2. UBUNTU recovery and
3. Windows Xp
Selecting any of the above doesnt work here. With option 1 & 2 it gives the error message
error: you need to load the kernel first
I am totally new to this UBUNTU.
Title describes the problem rather well. After selecting Linux 2.6.23-22-generic 64-bit in the GRUB bootloader, I am staring at a black screen with a white flashing underscore for almost 2 minutes (usually between 1min40sec and 2min). The Linux kernel is loading here, and it's taking forever!
Once Plymouth starts it barely even manages to flash into view before it's done and I get to login, so bravo @ Canonical.
But seriously, I need that boot time cut down A LOT.
