General :: Echo Function In .bashrc?
Feb 25, 2010I'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.
Fedora :: Timer Function Through Command Line?
Jan 13, 2010I've been working in a program in BASH and would like to measure its efficiency in different machines. Of course I am able to display the date at the beginning and at the end of its execution, but I'd rather use some sort of timer function to measure in seconds its speed. Is there any timer function available through command line?

Jun 14, 2011When I add some path in .bashrc by commenting out old path and adding new one like this:
#EXPORT HOME_PLAY=/home/gem/old_play
EXPORT HOME_PLAY=/home/gem/play
EXPORT PATH=$PATH:HOME_PLAY
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.
Ubuntu :: .bashrc Function Tab Completion?
Jul 4, 2010I tried to make a function to put in either my .bash_aliases or .bashrc file to make a local backup of a file, but when I call the function and try to use tab completion I get the following error:
Code:
cp: cannot stat `help': No such file or directory
The function I added is as follows:
Code:
function bk

Also interestingly, if I define this function at the prompt rather than in my .bashrc, tab completion works fine.

Mar 26, 2011I know my way around MS Windows much better, but I just don't feel right trying to program something for Android on a Microsoft operating system. I am interested in Android programming so I followed the instructions on [URL] to install the environment on my computer...
I just installed the JDK, SDK, Eclipse successfully (or I assume):
* When I get to Step 4 where I'm supposed to run 'android' it will not run. I get the error message "android: command not found" (I am definitely in the right directory).
** When I double-click it in nautilus, it opens up in gedit. I can set the permissions in nautilus (through the properties - Allow executing file as a program) and get it to work,
My system:

View 3 Replies View RelatedGeneral :: Function Having Background Process Inside Command Substitution
Oct 5, 2010The first call to "somefunction" works as expected. The function prints "endfunction" and a process in background sleeps 30 seconds. In the second call I thought it should work in the same way, but the script sleeps 30 seconds before it prints "endfunction".Does someone know the reason of this behavior? Is there another way to do a command substitution of a function that has a background process without have to waiting for that process?
View 2 Replies View RelatedGeneral :: Ubuntu 10.10 Installation Disc Not Recognized By Apt-get Command?
Apr 1, 2011I am trying to install the Broadcom wireless driver BCM4311 on my Acer Extensa 5420. I have consulted several help forums and tried several suggested ways of doing it. They all seem to require using b43-fwcutter, and my Ubuntu 10.10 installation always refuses to fetch it from the installation disk. The most straight-forward approach I have tried is as follows:
1. From the console, I type: sudo apt-get install b43-fwcutter
2. The command works for a while, then responds by asking me put the disc labelled " Ubuntu 10.10_Maverick Meerkat_ - Release i386 (20101007)" into the CD-ROM drive and press ENTER.
3. I insert the installation disc containing the installation program that I downloaded from the Ubuntu web site into the drive and press ENTER, but just get the same request again.
The file on the installation disc is named "Ubuntu-10.10-desktop-i386.iso", and the disk does not have a label. I have tried renaming the installation file with the intention of burning a new disc that would be recognized, but the name being requested is not a valid file name for Windows (so I can't do it on a Windows machine), and it also seems to be inappropriate for Ubuntu (it has spaces and may be too long). I also tried keeping the same file name and burning a disc with the requested label, but the burning software would not accept such a long label.

-s --scancodesdisplay only the raw scan-codes
-k --keycodesdisplay only the interpreted keycodes (default).
