May I ask a question about file permission. I set up Ubuntu server where Apache got running. I have simple php upload form and able to upload file to /var/www/site/uploads as follows. sandbox@sandbox-virtual-machine:/var/www/site/uploads$ ll total 1736 drwxrwxrwx 2 www-data www-data 4096 Oct 18 02:53 ./ drwxrwxrwx 3 sandbox sandbox 4096 Oct 18 00:42 ../ -rw-r--r-- 1 www-data www-data 145998 Oct 18 02:53 3d wallpaper pic.jpg -rw-r--r-- 1 www-data www-data 166947 Oct 18 02:53 3D Wallpapers 9.jpg -rw-r--r-- 1 www-data www-data 1451489 Oct 18 02:53 6453_3d_landscape_hd_wallpapers_green.jpg Is there anyway to upload files and they show up as -rw-r--r-- 1 sandbox sandbox 145998 Oct 18 02:53 3d wallpaper pic.jpg -rw-r--r-- 1 sandbox sandbox 166947 Oct 18 02:53 3D Wallpapers 9.jpg -rw-r--r-- 1 sandbox sandbox 1451489 Oct 18 02:53 6453_3d_landscape_hd_wallpapers_green.jpg so that I could straight away feed them to waiting/running shell script. Right now waiting script(move,checksums,rename,resize,etc) unable to do anything to uploaded files with attributes of www-data. If I just do as local account, such as sandbox@sandbox-virtual-machine:/var/www/site/uploads$touch testfile then the script is able to run as I would like to. Any suggestion would be grateful,thanks in advance as well. Thanks for everyone giving help to me,that I was able to progress. Now I am close to getting solved and append the output sandbox@sandbox-virtual-machine:/var/www/site/uploads$ ll total 388 drwxrwxrwx 2 www-data www-data 4096 Oct 18 04:22 ./ drwxrwxrwx 3 sandbox sandbox 4096 Oct 18 04:17 ../ -rw-r--r-- 1 sandbox sandbox 166947 Oct 18 04:21 3D Wallpapers 9.jpg -rw-r--r-- 1 sandbox sandbox 219808 Oct 18 04:20 adafruit_pi.png -rw-rw-r-- 1 sandbox sandbox 0 Oct 18 04:22 test How may I set permission to uploaded files like 'test' only w difference in middle group. Such as adafruit_pi.png Vs test. Which statement shall I insert to php code,please?
