I have a usb to serial converter which i plug in to Ubuntu Natty.I see that on every reboot this seems to come up as a different device name, say ttyUSB0, ttyUSB3 etc.I want to write a simple shell script to get the name of the device in a shellscript.
View 1 RepliesFrom one day to the other my system stopped booting properly. Since I (finally) fixed it, I wanted to share my solution. It runs on a fakeraid pair of SSD's of 60 GB each (actually a single Revodrive device, but it shows up as two devices). When Ubuntu 10.10 boots, I'm dropped to a shell.During boot, when I removed "silent splash" from the kernel's command line, I got these messages:
Code:
[ 4.960240] scsi 6:0:0:0: Direct-Access ATA OCZ-REVODRIVE 1.20 PQ: 0 ANSI: 5
[ 4.960425] sd 6:0:0:0: [sdg] 117231408 512-byte logical blocks: (60.0 GB/55.8 GiB)
[cod]....
I doubt that this is what was needed (as I had that already when it didn't work, but I might be required in addition to installing dmraid)
# update-initramfs -a
After installing this, the problem was solved!! This is strange since I don't recall uninstalling this package or changing anything important, for that matter (perhaps did apt-get upgrade, but that's about it!). [URL]
I'm working on a script to table the outputs of various commands that depend on each other. The commands are these:
Code:
[root@kybsdc2 ~]# raw -q /dev/raw/raw1
[root@kybsdc2 ~]# sginfo -a /dev/dm-5 | grep Serial
[root@kybsdc2 ~]# multipath -ll
which give these outputs:
Code:
#/dev/raw/raw1:bound to major 253, minor 5
#Serial Number 'P3e8hZWrsSeX'
#netapp (360a9800050336538685a577273536558) dm-5 NETAPP,LUN
[size=1.0G][features=1 queue_if_no_path][hwhandler=0][rw]
[code]....
Also the RAW13 device has completely wrong output due to 1 occurring more times throughout the sequence causing more information to be displayed then needed. The last point is if I could somehow remove the '' in the serial number outputs and the = sign from the device sizes. I guess I will have to either put a whole lot of logical IF or CASE statements in but somehow I need to streamline and make this code dynamic!
What is best way to replace the 1 and the 3 below with a 0 using a shell script? It is in a text file with lots of lines and similar lines:

I am trying to find / write a shell script that will go through a file organized like this (but with thousands of lines)...

579,1.00,"contig00003",3,380,"jgi|Brafl1|114745|estExt_fgenesh2_pm.C_1200006"
450,5.00,"contig00007",2,352,"jgi|Brafl1|274326|estExt_GenewiseH_1.C_8420008"
...and check the region of each line between the second and third pipes (the 6-digit numbers) against the values in the first column of a separate text file in CSV format like this...
274326,"Wnt family of developmental regulators"
114745,"FOG: Hormone receptors"
100379,"Transcription factor tinman/NKX2-3, contains HOX domain"
...and when they match, replace the value to the right of the third pipe (e.g., fgenesh2_pg.sca...) with the value in the second column in the CSV file associated with that number.
Hi I am trying to add the device by using followig code strip and it says that eth1 is not defind in the code.
strncpy(ifr.ifr_name,eth1,IFNAMSIZ);
if (ioctl(sd, SIOCGIFINDEX, &ifr) == -1) {
return 0;
}
How do I write down the DEVICE name in the ifr.ifr_name structure ?
I'm trying to get sound to work on an embedded board. The boot says ALSA is present and sound chip is present. So I try to open the device with:
The hardware manufacturer assures me the device is hw:0,0 so I set device to:
This gives me:
So I'm presuming the advice that I use hw:0,0 must be wrong? So I need to find a way of working out what the device id is. I've tried default, no effect, then tried the command asoundconf list, which returns an error. I'm using a min linux build on an embedded system (busybox) so is there a way to find my sound device.
can we find logarithm to base 10 instead of base 2 on shell script??i can do it with bc..like 'l(1000)/l(10)' | bc -l
View 1 Replies View RelatedRecently, I created a device sc0 through device mapper. The divice could be found in /dev/mapper/sc0. My problem is that the device doesn't exist in /dev/partitions which will block my following test.BTW, I found dm-0 in /dev/partitions. Is it the same as /dev/mapper/sc0? But the device /dev/dm-0 doesn't exist!

I am trying to create a shell script similar to ls, but which only lists directories. I have the first half working (no argument version), but trying to make it accept an argument, I am failing. My logic is sound I think, but I'm missing something on the syntax.

Is there some type of functional way to read things in the Python shell interpreter similar to less or more in the bash (and other) command line shells?
Example:
Code:
>>> import subprocess
>>> help(subprocess)
...
[pages of stuff to read]
...
I'm hoping so as I hate scrolling and love how less works with simple keystrokes for page-up/page-down/searching etc.
I just compiled my first own kernel (I'm using Arch Linux), following the tutorial on the german site. Now I tried to boot it, I ended up failing with this message: Code: Waiting 10 seconds for device /dev/sda1 ... Root device '/dev/sda1' doesn't exist, Attempting to create it.

I simply copy&pasted the Arch-entry, i.e. I also had the disk by uuid there.

(configured at user's .bash_profile).How do I force the session to close when user hits Ctrl-C or Ctrl-Break ?In a nutshell, I don't want user to have access to shell.

I was trying to find a shell script that will encode video to a an iso that I can burn for a dvd. It seems I have lost a few of my dvds and I backed them up into mkv and I need to convert it to pal so it will work until I find them. My search was leading to other formats, but I was wanting to use pal because it is smaller. My search lead me here, but this shell script is not in pal.I need a solution that would work with slackware.
