izzit possible to use a php exec function to trigger a jar file using -java method?ters/new.png"');However when I run the index.php, it doesn't trigger action.Instead when I run this code in the terminal, it works perfectly well.So is there any configuration needed to perform such action?Oh btw I'm using XAMPP in linux ubuntu and CBSim.jar to convert some images.
I have a bunch of .caf files in a directory that I want to convert to ogg but I cannot figure out way to do it (except manually). I want to do: sox filename.caf filename.ogg

I have a requirement to find the files having its name as ack_reply. However, there are many other files in the same directory as these resides. Now I have to remove these files from the folder and retain others after 7 days. So I tried to write the below script with grep command.
find $directory -type f -mtime +7 | grep ack_reply
how can I pass this output to -exec command.
If I am not using grep command my script would be as
find $directory -type f -mtime +7 -exec remove.sh {}\;;
trouble when I log in the fedora as a normal user(not root) today. When I fill the username and the password press enter key. Then pop up a little window locate at topleft corner. And have one line message : "/usr/bin/xterm : Could not exec /bin/bash : Permission Denied"hen I log in as root, it's ok. And when I open shell and type "su username" then the console print "su: /bin/bash: Permission denied"I have checked the perms of "/bin/bash" , it's 755. And I have tried all things which suggested from articles searched through Google. like change / or /root and other directory's permissions but failed
I did the chown task, as root, and the file icon still has the lock symbol on it. I did it on another file on my desktop just before that, and the symbol went away.I checked 'Properties', and it shows me as owner.It's an ISO on my desktop, copied from LXF Magazine DVD.
trying to run stuff from CD or DVD ROMS >without< copying to my cluttered hard drive, and came to a thought that I'd like evaluated: Would it work to perhaps use sed during the cd-rom auto-mount or some other point to enable the executable bit for *.exe and other 'executables' to somehow override the read only factor? I'm not too familiar with sed except that i know it can insert/replace new patterns of data for defined patterns of existing data.. so would something like this work? Could it be implemented as permanent function of Ubuntu to 'checkbox' cd/dvd mounts to insert the exec' bit on all, known, or choice files as a sort of 'virtual' permissions that can be placed on RO mounts?
My hosting company said: You need to unmount the partition with exec permissions, install memcached and re-mount it with no-exec as a security measure.
Code:
[root@server tmp]# pecl install memcache WARNING: channel "pecl.php.net" has updated its protocols, use "pecl channel-update pecl.php.net" to update
Within a bash script, I'm attempting to redirect file descriptors with exec, e.g. exec 3>&1 1>&2; however, I'd like to do something like exec $FD>&1 1>&2, which doesn't work because bash tries to execute the value of $FD. Various placements of eval fail, as well. Is there a way around this, or am I stuck hard-coding the descriptor?
Just coming over from Windows here... where I've been using "CreateProcess" which returns a value depending on whether the process was created successfully or not.
Now I'm trying to create a process on linux and I've been learning about fork/exec, and I've been struggling with the fact that there seems to be no easy way to know (within the original parent process) if exec succeeded or not. (without forcing the parent process to hang around polling it or something).
Anyway, I've now just discovered the posix_spawn function, and it seems exactly what I need. However I'm finding the documentation a little hard to understand. In particular, I can't find actual confirmation that it will definitely return an error if creating the process fails (like CreateProcess does on windows). So can anyone confirm that for me?
The text on the documentation states: "If posix_spawn() or posix_spawnp() fail for any of the reasons that would cause fork() or one of the exec family of functions to fail, an error value shall be returned as described by fork() and exec"
This makes me think it uses exec/fork under the hood, and so I wonder if it can be trusted..?
And also, most of the examples on the internet for creating processes use fork/exec, so I wonder if there is some catch with posix_spawn I haven't read about... (since it seems a much simpler way of doing things)
Im using gdb for debugging my application.. I was able to debug child process(when fork comes) .. and in child process we have an exec call to .... So the problem is, when the control come to exec , the exec process is executing at a time... I could not debug the exec. process... error is stack curruption due to same frame So, is there any way to debug the exec process
I have been struggling with this for about a week now. I'm working with QuickUSB to send video streams to and from a device. I get the fastest results by fork()ing and exec()ing new processes everytime I run a pipeline, which works great when reading from files, but now i have to transition it so that i am reading/writing data over a QuickUSB bus. I have it working for each individual process, but i can't run multiple processes because it won't let me open the device. After looking through QuickUSB's API a little closer, i found that the QHANDLE type that they use to describe the usb device is actually just a usb_dev_handle *. From what i have found, this is an incomplete structure, so i am having trouble with opening it in the main process and passing it to each new process to write to it. I already have semaphores set up to prevent multiple processes using it at the same time. I just CANT find out how to utilize the same usb device between two process that are forked and exec. i also must do the exec() because otherwise my gtk and gstreamer fails for trying to share resources.
I am looking for a default, or starting "exclude list" for system backups. We are currently using Symantec Backup Exec, but I also do not think that is important to this question. I would think that the Oracle "lock" files and the /var/run/*.pid files can be excluded from the backup, and probably the dell file also. Can some provide a list of files/directories that can be excluded (from backup) for RHEL 5?
I was told to simply go into the fstab folder to allow myself permissions to execute files without becoming root, but instead of following it blindly I need a 2nd opinion. I cannot install a specific program because of configuration problems even though I downloaded all the gcc, g++ etc packages.
I have used this guide to install kernel in my linux cyberciti.biz/tips/compiling-linux-kernel-26.html stage 1 worked perfectly. Now at stage 2 when I write the command dir/ls in the tmp directory I see the file: linux-2.6.26.tar.bz2 (2.6.26 is the version of my kernel) And now if I try to the tar function on my file and write it like this: Code: tar -xjvf linux-2.6.26.tar.bz2 -C /usr/src it gives me couple of errors like:
tar: bzip2: can not exec: no such directory tar: error is unrecoverable: exiting now tar: child returned status 2 tar: error exit delayed from previus errors
I'm in trouble when I log in the fedora as a normal user(not root) today. When I fill the username and the password press enter key. Then pop up a little window locate at top left corner.

And when I open shell and type "su username" then the console print "su: /bin/bash: Permission denied" I have checked the perms of "/bin/bash" , it's 755.

i had a problem with the find command in bash (which i deem is close enough to a promming language, if not please move this thread :P). i tried to reduce the command to the problem. i want the backticks, or $() for that matter; to be evaluated by -exec of find, not by bash. is that a caveat of find?
Code:
$ find testd -exec echo `basename {}` ; #confused me test test/a test/b
[code]...
edit: i found out whats causing this. `basename {}` gets evaluated by bash before find is invoked, returns {} and `find . -exec echo {} ;" is run. now my question is, how to escape this eveluation from happening before.
I am trying to automate an svnadmin dump command for a backup script, and I want to do something like this:
find /var/svn/* ( ! -name dir -prune ) -type d -exec svnadmin dump {} > {}.svn ;
This seems to work, in that it looks through each svn repository in /var/svn, and runs svnadmin dump on it.
However, the second {} in the exec command doesn't get substituted for the name of the directory being processed. It basically just results a single file named {}.svn.
I suspect that this is because the shell interprets > to end the find command, and it tries redirecting stdout from that command to the file named {}.svn.
I've been following the instructions to install Resin, and all seems to go well until I try to run the /bin/httpd.sh file. It simple says:
Code:
exec: 40: -jar: not found
I suspected this was something to do with my JAVA_HOME variable not being set, so I looked up how to do this and added it to my /etc/bash.bashrc file. Saying "echo $JAVA_HOME" does indeed return the correct path so I don't think this is the problem.
whenever I tried to boot into V1 in the following, it hang.
# uname -a Linux tadpole 2.6.32.12-0.7.1.1381.1.PTF-default #1 SMP 2010-05-20 11:14:20 +0200 x86_64 x86_64 x86_64 GNU/Linux # cat /etc/*release*

After using yast2 and install "xen" hypervisor, the bootloader show "V1" as label for Xen kernel, if I choose to boot into V1, it will just hang with very little message on screen:
Whenever I plug an external harddrive to a CentOS system,all partitions mounted will have noexec that makes my binaries or script files not executable.
Quote:
[root@centos52-64-dell ~]# mount /dev/sda3 on / type ext3 (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw)
[code]....
I have to remount it using, e.g.,
mount -o remount,exec /dev/sdb1
But I am sick and tired of doing it everyday. What I can I do ?I don't want to use /etc/fstab to solve this problem becauseit will cause booting problem (curable though) when the hard drive is not around.
