Software :: VIM Runs Into An Indefinite Loop While Editing A Large File?
Apr 12, 2011May I ask that does VIM support editing large files. I'm editing a 3G (good, less than 4G) text file with several millions of lines. I have deleted the first ~110,000 lines and :x (save and exit). OMG: this operation takes more than 3 days. I think it hangs already, so I terminated it. So my question is, can VIM do this???
Mine is:
VIM - Vi IMproved 7.0

General :: Shell Programming Using While Loop
Jun 28, 2010I am trying to do some shell programs. I tried some sites regarding the while loop, they give the structure as:
Code:
while [ n1 -lt 500 ]
do
echo $((n1+100))
done
But the below code also worked for me:
Code:
while ((n1 > 500))
do
echo $((n1+100))
done
By using (( )) I could use while, for. But the documentations didnt follow this way. I mainly use this for datastructure programming.

Feb 2, 2011Basically I have a dir that contains my makefile and another directory inside this called source this holds main source files. External to these I have a couple of dirs common and drives.
In my make file I use
To include the protoypes from the headers in the folders common and drivers used by source, this works fine. However in common and drivers I use a few variables that are set in the source dir. I set these with externs inside the common and driver files. However I'm sure I should be able to set the directory path for source inside my makefile. So say I have inside source hardware.h with prototypes, I set DINCDIR = -I/Source -I../Drivers -I../CommonFiles
Then from a c file inside my common folder I say #include "hardware.h" the file should be able to see hardware.h and it's protoypes. However I get:
Is there some way I can get the extern dirs to see the source dir?

Is there any way I can get the output on one line? Also, I need to raise a fault if any of the toners are below a specific level (with nagios you raise faults with the exit code) - any way I can do this without exiting the loop. Code below with bits and bobs commented out.

Programming :: Pass Arguments To A Function Using A Loop
Mar 1, 2010I need to pass a large number of arguments to a function which takes variable number of arguments, such as gtk_list_store_new. But it doesn't look nice if i write something like gtk_list_store_new(NUM,TYPE_A,TYPE_B,TYPE_C,...,TYPE_OMEGA); because of large number of arguments. And, it will be a trouble to change number of columns because of need to manually change arguments to large number of such functions. So, how can i pass all the arguments to a function using a loop? Something like
Code:
for(i=0;i<NUM;i++)
{
push_arg(args[i]);
}
call_function(func);
?
Of course, i could just use asm code for this, but is there a portable way of doing so?
P.S. i mean C language.
Programming :: Imagemagick With For Loop On The Commandline Does Not Work
May 26, 2011I have images in jpg format
Code:

CIMG0131.jpg
I used imagemagick to convert the files to gif with the following command
Code:
for i in {100..131}; do convert CIMG0$i.jpg CIMG0$i.gif; done # works
This worked like expected, but when afterwards I wanted to scale the images
Code:
for i in {100..131}; do convert -scale 25% CIMG00$i.gif CIMG00$i_scaled.gif; done # works not it seems the system is working for about half a minute, but I get no output. The single command
Code:
convert -scale 25% CIMG100.gif CIMG100_scaled.gif # works
works as expected and gives me a scaled image. What does the convert command do in the second case? is the for-loop wrong?
