Programming :: .bashrc Function Tab Completion?

Jul 5, 2010

I tried to make a (very simple) function to put in my .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
{
cp -f --backup=numbered ${1} ${1}.bak

Ubuntu :: .bashrc Function Tab Completion?

Jul 4, 2010

I 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

[Code]...

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

General :: Echo Function In .bashrc?

Feb 25, 2010

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.

General :: Make Zsh Completion Behave Like Bash Completion?

Jun 2, 2010

I switched to zsh, but I dislike the completion. If I have 20 files, each with a shared prefix, on pressing tab, zsh will fully complete the first file, then continue going through the list with each press of tab. If I want one near the end, I would have to press tab many times.

In bash, this was simple - press tab and I would get the prefix. If I continued typing (and pressing tab), bash would complete as far as it could be certain of. I find this behavior to be much more intuitive but prefer the other features of zsh to bash.

Is there a way to get this style of completion? Google suggested setopt bash_autolist, but this had no effect for me (and no error message was printed upon starting my shell).

Programming :: Passing Data From Interrupt Handler Function To Tasklet Function?

May 18, 2010

I am doing some Linux kernel programming for my research project. I need to record the timestamp (by using cpuid and rdtsc) when an interrupt handler (top half) is first invoked. Due to the time critical nature of the problem itself, I have to do the timestamping inside the interrupt handler itself (the first operation when the handler is called). However, I understand that tasks that are not so time critical should be deferred to a tasklet function (bottom half) for processing because other interrupts are disabled in a (top-half) interrupt handler. I am currently out of idea on how I can pass the timestamp information that I have obtained in the interrupt handler to the corresponding tasklet function.

Programming :: Bash Checking For File Write Completion Before Acting?

Jan 20, 2011

I have a bash script that checks for contents in a folder every 15 seconds and then acts on it's contents. This works great for the average size file however on very large files it starts acting on the file before it's completely written. Is there a facility in bash shell to get a file complete signal or such? here is trigger to launch a larger script.

Code:

#!/bin/sh
while true
do
$HOME/bin/hpgl.sh >/dev/null 2>&1 &

Fedora :: Add Path In .bashrc By Commenting Out Old Path And Adding New One - Command Source ~/bashrc

Jun 14, 2011

When 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.

Programming :: Surface Fitting Using NR Function Svdfit ( ) In C Programming?

Sep 16, 2010

fit a surface i.e. W(x,y) using svdfit() provided by "Numerical Recipes in C". svdfit() is written for curve fitting and not for surface fitting.But one can use svdfit(), as claimed by authors of NR book, to do surface fitting. On page 680 of NR book, authors have given a hint on how to use svdfit() for fitting a surface. But I have not understood it.This link may be helpful (Chapter 15 th is relevant here.):[URL]This is my problem:

Code:
I have a set of 100 numbers. I want to fit a 2-Dimensional function W(x,y) to these numbers.

Programming :: Accessing C Function From C++

Jul 5, 2010

i have an open source application that was developed in C++ (it uses objects and namespaces all over the place). I also have another application that was developed in C. Now i am trying to insert the code made in C into C++ application, but when i do that , i get this error on compilation of the source code:

Code:
error: 'mpi_init_vars' was not declared in this scope the function mpi_init_vars() is not part of object oriented programming and it doesn't belong to any scope, it was compiled into an object file and i am linking it with all objects of C++ application.

How can invoke the C function from C++ object oriented code?

Programming :: Gc-sections Remove All Function Not Used?

Nov 18, 2010

This is my file, named xxx.c. And there are two functions in it.

[code]...

When I try to compile the whole project, I used -ffunction-sections,-fdata-sections to generate the .o files, use Wl,--gc-sections -Wl,--print-gc-sections to link to the exacutable file. gcc 4.3.2 ld 2.18 Debian 5 After the first time I compiled it, I got a list of Removed functions. But one second later, I rememberd that I forget to close the Compile Switch: Debug. Then I had to recompile it and got another list. Compare these two lists, I found that , bxx isn't on the second list. First I guess that bxx is a debug function but never used in debug mode, and it won't be compiled in release mode. I check the source and find that there was no compile switch for bxx. But it's caller function axx, is removed, both the debug switch is on and off. I try to compiled the project for several times , but the result is the same. I can't realized it , why? Is that the --gc-sections won't remove all the functions not used?
