I have a Toshiba Satellite L505D-GS6000 it had windows7 on it when I bought it new. Needless to say windows just ran too slow. The only Ubuntu distro that would boot up was Karmic 9.10. I had to append the phrase acpi=off to get the live ISO to boot I had to type acpi=off after the word splash. I saw it would boot so I installed it as the only OS on this computer.
Now when I boot up I am hitting the power button once and the back on again to get to the grub. I hit the E key use my arrows down to the word splash type acpi=off. Then hit CTRL X to boot up. How do I put this permanently into Grub2.
After saving above changes, I enter the command: source ~/.bashrc Now if I do echo $PATH, the path shows both the old PLAY_HOME and new PLAY_HOME. This is really bad and messes up a lot of things in my project. This problem only goes away if I logout or reboot, a rather very long process. What is happening is that the old path is added to new path element and the old path includes the old path element you want to remove.
IN 3.5.10 I am able to display the full $PROMPT_COMMAND environment variable in the Konsole title bar. Kind of handy and I did not need to display that information in the $PROMPT variable.
In 4.5.5 I am having trouble figuring out how to make that work correctly. The title bar displays only the directory name rather than the full path and user name.
This is my $PROMPT_COMMAND:
history -a;echo -ne "33]0;${USER}@`uname -n`: ${PWD}07"
All I see in the title bar is:
dirname: bash
I should see:
username@hostname: full path to present working directory
I'd like a function in my .bashrc file that would allow me to pass text to it and echo the text to a specified file. I know it's simple as "echo 'text' >> file," but ideally, I would want to alias the function so I execute something like:
Code: user~ $ write 'this is a test' with "write" being the function, and 'this is a test' being echoed to the file. I hope I explained that well enough.
A cluster with a head node and compute nodes. An application with a couple of env variables (App_HOME, PATH) set in .profile (default shell sh). If I login to the head node/compute nodes on a terminal everything works fine. The correct env variables are set and the application works. However, when my application tries to do it, say ssh <compute node1> <application>, it appears the environment variables are not available. It only looks in the minimal /bin, /usr/bin type PATH. This tells that the .profile is not being read
I am combining data from a couple different input files and creating an output file in a specific format. I notice that if I use the >> operator, information gets appended to a new line in my output file. This is useful, but if I'd like to append onto the CURRENT line, is there an easy way to do this? I've been googling around and see lots of complicated answers, nothing that suggests to me an easy way to do this. For example, if my output file looks like this:
b1a:] cat test hello my name is b1a:]
and I'd simply like to append "Bob", how can I do it? If I use
b1a:] echo Bob >> test b1a:] cat test b1a:] hello my name is Bob b1a:]
So what I would prefer is some command that would create the result:
I need to source the my /home/me/.bashrc file every time I "su -" to root. Is there any way to automate this? I cannot edit any thing in the root's environment as it is shared by people.
In my .bashrc file, I am attempting to set JAVA_PATH to a local path, using the HOME environment variable or '~' symbol as shown in the following examples.Using ${HOME}
When I attempt to use ${JAVA_HOME} in a my ${PATH} javec is not found. To debug it, I tried a simple ls command:
ls ${JAVA_HOME}
and get the following error:
ls: ${HOME}/Software/java/jdk1.6.0_24/: No such file or directory
Using '~': Trying to use '~' symbol as follows:
export JAVA_PATH='~/Software/java/jdk1.6.0_24'
the ls command results in the same error, however javac is found.I prefer the '~' symbol anyway, but would like to understand why the ls command does not work for either, and why it seems as though ${HOME} is not being expanded.
I am trying to include my directory /usr/sbin in it's serch path for executable files using an environment variable. Would the input be: PATH="/usr/sbin"? And also upon start up, my shell should create the PRINTER environment variable which should resolve to the word sales...would that input be: PRINTER="sales"? If someone could help me with these two questions,
The problem is I can't use $0 as reference because the script is only sourced not executed. I also don't want to hardcode the path because the location might change and there will be more copies. Is there an easy way to create this information from within the the sourced bashrc file? I use Gnu bash 2.05b on Suse Linux 9.
I have a problem with my script. The problem is the system keeps rebooting after I put the directory file in .bashrc. The intentional for putting the file in .bashrc is to run the script automatically after login as root, I don know why is this happen. It was working fine for the first time without putting the file in bashrc. I could break the loop after hitting the "ESC" key. would it be the script problems?
Here is my script count=20 while [ $count -gt 0 ];do sleep 1 echo Press ESC to break the operation ((count=count-1))
I have installed a software and set the variables in the .bashrc file to avoid setting them everytime I would like to run te software. Now I have installed a new software and would like to do the same thing in the .bashrc file.How can I add the path to the new software directory without affecting the first software path.
I want to play around my .bashrc file, but I can't seem to find a general guide to customizing it. I just want a guide that will show me examples and explain them in-depth.
