I have a linux system in a target board(Not GUI), which boots up and doesn't give me a bash prompt. So to get a bash terminal, I always need to telnet to it. (It is starting a telnet server during bootup) Please let me know how to get the terminal in the same window where it boots. In otherwords, once the rc.sysinit completes, I need to have a bash terminal there.

Yesterday I thought I had solved my "Blank screen boot"-issue when I successfully got to the terminal login screen without the screen going black by booting with
Code:
Linux acpi=off
I spoke too soon. I found out shortly after that when trying to "startx" with acpi off gave me these errors:
Code:
WARNING: Error inserting i2c_algo_bit ("filepath"): No such device
WARNING: Error inserting intel_agp ("filepath"): No such device
[Code]....
Then I read somewhere that booting with "i915.modeset=0" might work. So I removed acpi=off from lilo and added this, and sure enough, I got to terminal login, but I get the same errors with "startx".
I must make it clear that I can successfully perform startx when I boot without "acpi=off" or "i915.modeset=0", I am unable to see the screen but I can hear the KDE fanfare, etc.
I am working on a embedded target board which runs on linux. The target board is connected to a linux machine through serial port. To bootup the target board, I run the minicom in the linux machine, boot the kernal of the target board through giving the boot command through the serial console (minicom). Now the question is when the target board boots up, it doesn't starts a shell. The rc scripts are getting executed. There are target specific applications getting started from the rc scripts. I appended & to the last launched application. Still I don't get shell prompt.

After upgrading to Lucid said adapter is nonfunctional - NetworkManager won't start on booting (I'm using 2870sta module) and it finds no networks - neither does WICD.

upload a file to a business partner of ours in another country. Currently they have an SFTP server set up for us that I am using to download a daily generated file from a previous requirement. I use a bash script to download it since its fairly simple.
Quote:
sftp username@address/filename_filedate.zip /home/user/filedirectory > /var/log/joblog
(removed private info) To satisfy the new requirement I have been trying to write something similar to this;
Quote:
sftp /home/user/filedirectory/filename_filedate.zip username@address:/remotedirectory/
sftps manual page only gives a hint about using a batchfile, however i still cannot get it to work. Does anyone know another way? Or if you can even suggest another method or application? It seems like a bit of a cop out you can EASILY download using the sftp command but can't upload.
EDIT - forgot to mention I have already got keyless entry set up using ssh keys.
im a rookie at configuring linux and i have problem booting slackware 13.1 just installed. i get a message similar to this Kernel panic - not syncing: VFS: Unable to mount root fs on unknown- block(8,4) i got this one from another user who has a similar problem, they say i should fix lilo.conf and it actually was pointing to a wrong partition so i fixed it. i also fixed /etc/fstab to make it point to the right partition /dev/sda3. but after fixing the files, it still wants to load something in /dev/sda4, i dont know why so what should i do next, please explain with commands and not just words. edit this is my lilo.conf

i decided to install ubuntu in my PC,i downloaded the .ISO image and i installed it in my USB. After trying it and all that i observed that i really liked it and i decided to formally install it to my computer in the hard drive. When i reached the partition thing,i selected to dual boot with Vista and select between each them in every startup,when i clicked FORWARD it gave me an error which i did not read(because,again im a noob) so i clicked cancel.
Today i wanted to go through the process again and now really install it,so again i went to the time zone part and i clicked forward but then,instead of taking me straight to the partition phase,it appeard a window saying "The installer has detected that the following disks have mounted partitions: /dev/sda ...." I clicked yes,to unmount this partitions so it took me to the partition thing,once there i selected the option to install Ubuntu with Vista and select between them i neach startup,then i clicked forward and went to the username/computer name process,once i finished i continued to the next part,the installation,but i selected to import all of my WIndows VIsta default user data,after that i clicked forward and went to the installation process,i went down stairs to eat soemthing while it finishes,i came back and it was finished,it asked me to reboot so i clicked in Restart Now.
When it tried to boot,appeared an error saying: Error: no such devide found: #################### Grub load(or something like that) grub rescue: and it was a command line,since there i havent been able to boot into vista or Ubuntu,im really scared because is the first thing related to OS installing ive done,so i booted my USB and ran the trial and right now im trying to find out what to do from that trial version.
I just went to the INSTALL UBUNTU 10.04 LTS application under the System>Administration Menu and found out that in the partition phase the Install and allow to select between both systems in eahc startup option,i dont know what to do,i foudn out that my HD has still all its data(MUsic/Videos/Folders/Programs/ect.)its just that i cannot boot from it. Also in GParted it appears as /dev/sda1/ and a warning icon besides it,also when i go into information, thers this warning there [URL]

How come code behaves normally and stops when ctrl+c signal is caught and resumes, but after I use at least one timeout read in the code it looks like, if signal is caught again it doesn't pause the execution but skips the loop. If you remove -t (timeout) option from the read, both loops look the same!

I have written quite a few separate bash & scripts and php scripts that up to now I have run from cron jobs. However I have to estimate how long each takes to run, before running the next and so it probably takes much longer than necessary to run them all. They have to run in order.
Now there are so many I am thinking it would be better to have a master bash script that would run one after the other, but I am not sure how to get the master script to wait before starting to run the next script. Is this possible and is there a command that will make the script wait between bash and php scripts , for them to finish, before running the next?
I have searched and searched and maybe I don't know how to articulate this issue with out just posting the problem I'm having. Every time I bring up a terminal window I get the following "Header"

To be honest I cheated and used the .bashrc / .profile files from Ubuntu and all was working fine for a while now and it seems something changed to cause this... any ideas on why I am getting this? I checked my .bashrc and my /etc/profile and it doesn't look like anything is amiss..
I would like to get the filename (without extension) and the extension separately. The best solution I found so far is:
Let FILE="thefilenameofsomefilesfor_instance.txt"
Code:
NAME=`echo "$FILE" | cut -d'.' -f1`
EXTENSION=`echo "$FILE" | cut -d'.' -f2`
I think it would be better to count the len and remove 3 chars to right to get the extension, but it can be macintosh filenames with have 4 chars for extensions.
I've noticed something, and hoped there was a work around.when I write a simple bash script, and run it, if I close the terminal i ran the bash script inside, the bash script stops. What are the solutions for this? Basically I want to run my bash script and close the terminal, keep the bash script running.
View 6 Replies View RelatedWhat happens when the script executes is that the ssh connection works and parks me at the remote hosts's shell login. Therefore, the "firefox" command refuses to execute. I need to know how to make the "ssh" connection occur, stay open, and go into the background so that the rest of the script can execute.If I could also do this with the "firefox" line so that the entire term window could be closed would also be helpful.
