Terrible title, sorry. I used cmake to generate a makefile and I specified g++ as the C++ compiler and when I run the generated makefile using make or gmake I get all these compile errors and all my symbols have trailing â's on them. Any thoughts on what might be behind these mysterious â's? ...

In UNIX, I have a utility, say 'Test_Ex', a binary file. How can I write a job or a shell script(as a cron job) running always in the background which keeps checking if 'Test_Ex' is still running every 5 seconds(and probably hide this job). If it is running, do nothing. If not, delete a directory at the specified path. ...

Hello everybody. I'm looking for something,I don't know if it exists. I have a Java server, something like while (true) { try { Socket socket = server.accept(); new ConnectionHandler(socket); System.out.println("Waiting for a new client message..."); } catch (IOEx...
What is the relative overhead of calling times() versus file operations like reading a line fread(). I realize this likely differs from OS to OS and depends on how long the line is, where the file is located, if it's really a pipe that's blocked (it's not), etc. Most likely the file is not local but is on a mounted NFS drive somewhere ...
Suppose I'm at revision 50. But, I want to revert back to revision 45, and commit back as the stable version. How do I do that, in the most simple way? What if I want to do that with one file? What if I want to do that with the entire repository? ...

Hi, I have written 3 .sqc files i.e. embedded sql in host language C. I need to make a (Unix) shell script to simply compile all 3 sqc files in a row. How can I do that? Right now, I can individually run each .sqc file using a Makefile that basically converts the .sqc file to a c file and then compiles it. Can I make 3 individual Makef...

I'm trying to get a list of the CSV files in a directory with python. This is really easy within unix: ls -l *.csv And, predictably, I get a list of the files that end with .csv in my directory. However, when I attempt the Python equivalent using the Subprocess module: >>> import subprocess as sp >>> sp.Popen(["ls", "-l", "*.csv"], s...
Usually every time `make install' is run, files are not put in a specific directory like /usr/prog1. Instead, the files are put in directories where files from other programs are already in like /usr/lib and /usr/bin. I believe this has been a common practice since long time ago. This practice surely increases the probability of file nam...
I'm compiling parallel C code on a cluster (HECToR). Although I won't be running any parallel jobs interactively, my code contains some references to X11 functions which are used when it's run sequentially. The cluster I'm using doesn't support shared libraries, which rules out X11, at least in the way I've been using it so far. Could ...

I'm writing a simple file-caching engine in PHP that needs to be able to see how big a directory is. What I'm looking for is the equivalent of Unix's du command to simply print the total filesize of a directory. I can write it myself, but if somebody else already figured out all the issues of recursing and handling symlinks and so on, ...
