I'm trying to run a shell script owned by a non-privileged user from PHP on an Ubuntu server. Issues with permissions make running it with exec() impractical, as it's www-data that's running it. I've googled a bit and found varius references to suExec (which seems too much of a hassle to get working for such a small problem), setting the...

I am trying to run ffmpeg via the exec call on linux. However I have to use quotes in the command (ffmpeg requires it). I've been looking through the java doc for processbuilder and exec and questions on stackoverflow but I can't seem to find a solution. I need to run ffmpeg -i "rtmp://127.0.0.1/vod/sample start=1500 stop=24000" -re -...

Then I changed to use , and that's where I got stuck. My target is like: <target name="test"> <echo message="${basedir}"/> <exec executable="cp " os="Linux" spawn="ye...
I'm trying to execute some program: exec -ignorestderr "bin/tecs-software-suite-2.5/JackCompiler.bat" "$current_file" the program writes to the stderr, so tcl shows an error dialog similar to it's ordinary errors. I don't want that, I simply want it's error output(all it's output) to be in a TK label. I added an ignorestderr but it do...

Hi, I know it is common to use catch when executing commands that may return non-zero... but how can I get the output in that case? To be specific, I wish to do something like "catch {exec diff fileA fileB} ret". The files are different and ret value is 1. What I actaully need is the output of diff, the detailed differences. But I bel...

This is annoying when something gets stuck and I need to see what the last line says. Is there any way to make stdo...
I have a dedicated server that I use to crunch lots of data. The way I have it now, I can open a script with a process ID like example.php?ex_pid=123 and just let it go. It downloads a small portion of data, processes it, then uploads it into a database then starts again. Ideally, I would like to call example.php?ex_pid=123 directly and...

Some of the expressions may want to save their work afte...
I've written a remote Python debugger and one of the features I need is to execute arbitrary code while stopped at a breakpoint. My debugger uses the following to execute code received from the remote debugger: exec (compile(code, '<string>', 'single') , frame.f_globals, frame.f_locals) This works fine for the most part, but I've noti...
