This is something really simple, but I can't seem to find the answer anywhere, and I'm new to both Mac and UNIX, which doesn't help. I've installed Xcode on my mac, along with the iPhone SDK 3.2.

David Korn, a proponent of the Unix philosophy, chided Perl programmers a few years ago in a Slashdot interview for writing monolithic Perl scripts without making use of the Unix toolkit through pipes, redirection, etc. "Unix is not just an operating system," he said, "it is a way of doing things, and the shell plays a key role by provid...

Hi, this may not be strictly about programming, but if I find no ready-made solution it may become a programming task: On UNIX, what is a command-line method for determining the user-preferred application for a given filetype? My ideal solution here would be a command that stopped me having to do the following: okular foo.pdf And al...

Hi, I'm working on an audio encoder cgi script that utilises libmp3lame. I'm writing in a mixture of C/C++. I plan to have an entry-point cgi that can spawn multiple encoding processes that run in the background. I need the encoding processes to be asynchronous as encoding can take several hours but I need the entry-point cgi to retur...
Hi, I have some basic questions about pipes I am unsure about. a) What is the standard behavior if a process writing to a pipe gets killed (ie. SIGKILL SIGINT) Does it close the pipe? Does it flush the pipe? Or is the behavior undefined? b) What is the standard behavior if a process returns normally? Is it guaranteed to flush the p...
I've been developing Microsoft Windows based applications (both desktop and web) for several years using C#, .net, & Visual Studio with a dash of C/C++ & WIN32. I want to broaden my horizons and try out developing in a *NIX environment e.g. using Vim & C++. I have limited UNIX experience from a few school projects. I'm having trouble ...

I 'm writing a little program that implements pipes like they work in the shell. ie: ls -hal | sort | grep p | wc it works fine, with the minor issue that on one line, when CMD_NO=n, the comparison i biggerthan CMD_NO does not work, but i!=(CMD_NO-1) does. I'm trying to figure out why in this particular case (the line is ocmmented a...
Is this the proper way to define an include path for both *nix and Windows? define( 'INCPATH', realpath( dirname( __FILE__ ) ) . '/' ); Note the trailing forward-slash I included above. Is the forward-slash for includes/requires the same for both OS's, as well? EDIT (UPDATED WITH ANSWER): From what I can gather, my code below is the...

Hello, when I want to execute some shell script in Unix (and let's say that I am in the directory where the script is), I just type: ./someShellScript.sh and when I want to "source" it (e.g. run it in the current shell, NOT in a new shell), I just type the same command just with the "." (or with the "source" command equivalent) before...

I have the following bash script, that lists the current number of httpd processes, and if it is over 60, it should email me. This works 80% of the time but for some reason sometimes it emails me anyways when it is not over 60. Any ideas? #!/bin/bash lines=`ps -ef|grep httpd| wc -l` if [ "$lines" -gt "60" ] then mailx -s "Over 6...
Hi, I am considering which scheme to use. I would like to use a scheme that has or can be compiled to have no threading support. I have to avoid the layers that threading libs provide. I want an implementation that has no code for interpreter locks, etc. Something that can compile to C is ideal. This will be Unix only. Chicken and Gambi...
