Programming :: Pyqt3 Def Works But Not Vey Well?
Mar 10, 2010want to get a text file and use sed commands on it to make it more manageable.(because I don't know how in python) Then take each line based on what it starts with and send it to the proper lcdnumber.display. I need an adjustable "pause" to allowing slowing down of the entire process equally but I think the way I'm using the time.sleep is messing things up as only 1 in 10 value sets make it to the lcd and sometimes some of the segments don't get drawn. Also the x digit and the y digit are now being sent to one lcd how can I grab just the first half of the double value xy up to the space as x and then grab the remainder as y so all three xyz values go to three separate lcd displays? I attached 2 files one before and one after the formating.

Programming :: Pyqt3 List Without Comma ?
Mar 21, 2010I'm trying to compose a line of numbers each single digit taken from a variable eg: 1010001 each variable digit is either a 0 or 1 made from variable layer1 through 7. I need to add each layer variable to the last to compose the number with no commas or spaces and add it directly after the -p option in the show_command line. I used array and list and the commas mess up the command and inserting "pens" in the show command interpertes it literally instead of the list or array value? The insert should look something like 1000110

I tried the same thing with an LCDNumber but it only updated every 10 value changes? After each change do I need to clear the textLabel or refresh the window? For testing the print z and print x in the code prints the values correctly.Heres my code:

Ubuntu :: Syntax Ls Command Question For Generating Links?
Aug 6, 2010I am trying to find out can I use the ls command to list my wav files in such a way that it follows this format: <OPTION value="/home/filepath.wav">My first file </OPTION> I would like to know if there is a way I could simplify this because I have about 100 wav files. They all have names and if I could get them listed then a space then the name again with something behind it I could use the find replace feature to generate a bunch of links . If not is there a script out there that could use this format to generate links under this format? BTW this is for a pull down menu that would control windows media player

General :: Command Syntax To Modify Multiple Files
Sep 26, 2009I have a program I use, rrdtool. I need to modify a ds value on every file at the same time. However, using a wildcard (*) to try this operation of all files does not work and instead only updates one file.
Here is the command syntax:
rrdtool tune <file> --maximum traffic_in:100000000000 && rrdtool tune <file> --maximum traffic_out:100000000000
So, how can I do this on every file in the directory?
Software :: Vim - Command Input For Creating Syntax Files
Jan 25, 2011There is a syntactical feature I would like to see in Vim, and so I thought to write myself a syntax file for my needs, but I am having trouble finding the exact type of syntax highlighting I want to incorporate'emulate. Currently in Vim, from the terminal instead of say gvim, when I place my cursor over a parenthesis or brace, the corresponding brace or parenthesis will highlight, or block its character. In my case, instead of a single character they will be full words specified within the syntax file.
I want to do something similar. For example if my document has three words:
Group
Element1
Element2
I want the syntax file to tell Vim that when I have my cursor over the word Element1 or Element2 that Group will become highlighted. In the same, to have the cursor over Group will cause both Element1 and Element2 to highlight. I have looked here but understanding still eludes me: [URL]. I would also be happy with creating some sort of command input, where I type in the group name and the elements highlight. Like a very specific search function that searches for only and all instances that are contained within the group named.

View 6 Replies View RelatedGeneral :: Command Syntax Ignore Remaining Portion After Space?
Jul 14, 2010I'm currently studying for my Linux+ test and I'm getting conflicting information regarding the rm -rf command. Yes, I know this a dangerous command, but my question is in regard to how the command functions. In one book I'm studying it says that rm -rf / home/myfolder (there's a space in there) will delete the entire root directory because there is a space between the root and home directory. It says that if there is a spacing such as this, it will ignore anything after the space, so in this case, it would delete the root directory and stop, not that there would be anything left anyway. Then in another book I have, it says that if you did a rm -rf folderName / (with the intention of adding the trailing slash to indicate it is a directory and not a folder) it will delete everything in folderName (assuming it's a child directory of your pwd) and then CONTINUE on and delete the root directory. Now, those two statements contradict each other. When you remove a directory, does the command line ignore anything after a space or not?

Ubuntu Security :: GRsync --Exclude Command Syntax / Backup A Whole Startup Disk To Another?

For example, I don't want to backup my 'swapfile1' (I do not have a dedicated swap partition) or the 'media' directory' in order to no enter a looping sync.I've searched the web for the correct syntax of the --exclude command but none have worked if applied in the advanced option "before" rsync starts.

same for swapfile1:

Programming :: Syntax For Passing Arguments In Csh Aliases?
Mar 22, 2009I want to write a little time-saving alias for my .cshrc file that will move files and then cd to the directory I've moved them to. What I can't quite figure out is the syntax to say 'move all the arguments except the last one.' Here is what I have:
alias follow 'mv !:1-$-1 !:$; cd !:$'
This actually seems to work, but it also gives me an irritating error:
mv: cannot stat `destinationdirectory/-1': No such file or directory
Similarly, I tried:
alias follow 'mv !:*$#argv-1 !:$; cd !:$'
Again the move and cd are successful, but again there is an error:
mv: cannot stat `destinationdirectory/0-1': No such file or directory

Programming :: C Syntax - Passing In Unknown Number Of Arguments?
May 18, 2009I need to write a wrapper function around the mvprintw function, like so:
int smvprintw( ? )
{
// Do various checks/modifications on the first two arguments (int y,
int x) first,
// and then
return mvprintw ( ? );
}
How should I write the args for smvprintw so that I can pass all the data correctly to mvprintw, and also do my checks on the first two args (for example, to modify them)? I'm confused by the prototype of mvprintw: This is mvprintw as listed in the man pages:
int mvprintw(int y, int x, const char *fmt, ...);
And this is how I saw it in ncurses.h:
extern NCURSES_EXPORT(int) mvprintw (int,int, const char *,...)
I believe the "..." refers to the unknown number of items after const char * fmt. Will it suffice to do something like "int smvprintw(int y, int x, const char * fmt, void * etc)" and then "mvprintw(y, x, fmt, etc)" inside the function?
