Binary files need only execute permission to execute. No read permission is required. But all executable files must be read by the kernel into main memory before executing. Also script files need both read and execute permissions for executing the file.

View 1 Replies View RelatedI'm using Ubuntu and I'm programing with eclipse CDT. My goal is to execute a php file and read the output to my c++ program. To do so I thought I should use fork(), dup2() and execl. When in shell, the call "php myscript.php" worked just fine, but when in c++ I tried:
execl("usr/bin/php", "php", "home/geiger/workspace/SemiServer/server_content/myscript.php", NULL);
And it didn't work (the process wasn't terminated and I got no output). I tried different version of this call, like losing the "php" string and/or drop "home/geiger" from the path string, to no better result.
I am looking for a clue in shell or ant script, where I excecute a binay file on linux. For example ./myfile.bin which ask me few questions.
./myfile.bin ...........................100%
I would like to automate this process where I want to pass the hostname as a variable or read from a file is it possible? If yes any sample`s on this. I can do if this was a shell script ($1) but not sure when its binary.
I've checked out a subversion project with source c++ files in netbeans 6.8 on Red Hat 5.5. My machine has a dual boot with windows xp and RHEL 5.5 so I checked out the project on a folder called winshare which is a shared drive/partition (E: under xp) allowing both operating systems to access the contents. I've Fedora as virtual machine on xp and wanted to be able to work on the source seamlessly whether using fedora or RHEL.
Problem is that Netbeans is able to build the source just fine but I can't seem to run the generated executable. It has -rw-rw---- permission and the owner is the same user logged in (let's say user1) but no matter what I do, whether I change permissions as user1 or root issuing command chmod 777 -R /dir/where/file/is does not have any effect whatsoever on the executable as well as any .cpp or .h files (nothing that I need exectue permissions on .cpp but just to make a point).
Is there a Linux command, or a series of commands, which will allow me to get the permissions of a file in "0644" format?

View 3 Replies View RelatedI've hit a wall here; I'm attempting to find some way by which to view files and cd into directories on a device mounted read-only. So I need the permissions to read, write, execute (and the same with directories), but chmodding is out of the question because I don't want to alter the drive one iota.
I guess what I could do--what I was thinking of initially--was to dupe the whole drive and then mess with permissions. This wouldn't affect the original (actually I'm working on a duplicate of the original, but I'm treating it as if it were the original) but I was hoping for something that would maintain data integrity. This is a forensic application and not altering the data is very important.
A bunch of my .rtf files suddenly (within the last few days, not sure when) have the "Allow Executing File as Program" box checked under their file Permissions. So whenever I try to open an rtf document, it asks if I want to run it. What's up with that?
View 3 Replies View RelatedI want to simply mount an ext4 file-system onto a normal mount point in Ubuntu (/media/whereever), as read-writable for the current logged-in user, i.e. me.
I don't want to add anything into /etc/fstab, I just want to do it now, manually. I need super-user privileges to mount a device, but then only root can read-write that mount. I've tried various of the mount options, added it into fstab, but with no luck.
im trying to execute a file. When I try i get the message:
The file ...Installer.exe is not marked as executable. If this was downloaded or copied from an untrusted source, it may be dangerous to run...
So when I right click on the file and select properties>permissions and check the 'allow executing file as program' it instantly unchecks the box. I can't check the box.
Suppose I have a binary program with only execute permission enabled for the current user. How (in general) would I be able to obtain a core dump of the file? I think I have read it somewhere but I want to know if there are more ways of doing it.

I have this scenario, where in I'm calling a shell script inside another shell script. The only criteria here is that the embedded script will have 654 permissions and the master script should be able to execute this embedded script. The sample code is given below:
#!/usr/bin/ksh
maindir=/usr/home01/temp/dir
bindir=${maindir}/batch/bin
${bindir}/test.ksh -d ${dblogin} -i ${datadir} -r ${filedt} > ${tmp_log}
The test.ksh which has 654 permissions is called by the main.ksh script and when I try to run it using ./main.ksh, it fails with the error "Execute permissions denied."
I've been looking around the net for executing a shell script. My basic understanding is that after setting executable permissions and providing a path (#!/bin/sh) in the first line of the script, I can type ./myscript to execute instead of sh myscript. This is not working for me. I can run "sh myscript" but not "./myscript" even though I know for sure I have across the board execute permission and my sh path is correct. I'm working on a redhat linux station.

View 9 Replies View RelatedI have apache2 running on my computer. I want to change the permissions for /var/www/ so that I can edit the files without a problem. Right now I can use the gksudo command, but I'd like to be able to have all the files available when using an IDE like eclipse.
I've read in several places that
Code:
chmod 755 /var/www
will do, but if I'm not mistaken that would give read/write access to anyone. I'm not in a production environment, so I'm not too worried about security, but I'd like to give anyone else as less permissions as possible. Would this be possible?
I am running Linux Mint on my primary hard drive, and I would like to access some folders I have on my second hard drive, which has Windows XP installed on it. However, whenever I try to use these folders, I am greeted with the error message, "The file is not marked as executable." While I know how to set files as executable whenever I am using folders on my Linux drive, whenever I try to set such permissions on my XP folders, I can't seem to make it work. The files revert to their former status, and I'm told that I don't have permission. Should I set the files as sharable from within XP, so that they aren't marked as read-only? Or is there another solution I've missed?

I have a CMS that has a brilliant backup option with one flaw, it can only create a full backup in a directory inside the web root. In this case /var/www/site/backups. This is not practical for security as the resulting tar.gz file contains a full mysql backup as well as other items that the general public shouldn't be downloading.What permissions do I need to set so that the directory /var/www/site/backups cannot be browsed to in a browser but can be read / written by the CMS when a PHP script calls it?
