Para entender mejor el concepto de permisos se tendrá que tener en cuenta que cada usuario puede pertenecer a uno o más grupos. Cada usuario pertenece por lo menos a un grupo, que es establecido en el momento en que el usuario se crea.
El administrador del sistema puede agregar al usuario a otros grupos. Estos grupos son necesarios para poder establecer una política de acceso más organizada dado que en cualquier momento se podría dar a un archivo el acceso a personas de un grupo determinado. Lo único que se tendría que hacer es agregar a los usuarios que se quieran dar permisos a ese grupo. Para cada objeto (archivo) que se encuentre en el sistema, GNU/Linux guarda información administrativa en la tabla de inodos, tema que abarcaremos en mayor detalle más adelante. El dueño de archivoEl grupo del archivoLos bits de modo o también llamados permisos de archivo En este tramo nos centraremos en primer medida en entender los permisos y en establecer la forma en que pueden trabajar con ellos.
Linux - How to give file permission to a specific user in a Group. Linux/Unix: List All Users In A Group Command. To see user's groups or group's users use any one of the following command: grep '^groupNameHere' /etc/group lid -g groupNameHere members groupNameHere awk -F':' '/^groupNameHere/{print $4}' /etc/group getent group | grep -i 'groupNameHere' In this example find all users in a group called cartoon. grep command example grep '^cartoon' /etc/group Sample outputs: cartoon:x:1009:tom,jerry,spike,tyke,butch,nibbles,quacker lid command example lid -g cartoon Sample outputs: tom(uid=1007) jerry(uid=1008) spike(uid=1009) tyke(uid=1010) butch(uid=1011) nibbles(uid=1012) quacker(uid=1013) members command example members cartoon Sample outputs: tom jerry spike tyke butch nibbles quacker awk command example awk -F':' '/^cartoon/{print $4}' /etc/group Sample outputs: tom,jerry,spike,tyke,butch,nibbles,quacker getent command example This example with NIS and other database too: getent group | grep -i '^cartoon' Sample outputs: See also.
FreeBSD is here! Running FreeBSD on Raspberry Pi. There are several different Linux based distributions available for the Raspberry Pi, including Raspbian, Arch Linux and Fedora. However Linux isn’t the only operating system that can run on the board. Among others, including RISC OS, is the popular Unix-like operating system FreeBSD. FreeBSD has a deep heritage and is in fact derived from the Berkeley Software Distribution (BSD, sometimes called Berkeley Unix) a version of Unix produced by the University of California, Berkeley. For copyright reasons, FreeBSD isn’t allowed to call itself Unix, however; it is actually more Unix-like than Linux. For those who are interested in running FreeBSD on Raspberry Pi, here are the installation instructions.
FreeBSD has supported Raspberry Pi since November 2012, and the current production version (FreeBSD 10) is available as a pre-built image which can be copied onto a memory card. Download the latest image file from the official FreeBSD ARM page. Unzip the Win32 Disk Imager .zip file. Arm/Raspberry Pi - FreeBSD Wiki. FreeBSD/ARM on Raspberry Pi FreeBSD-CURRENT has supported Raspberry Pi since November, 2012 and Raspberry Pi 2 since March, 2015.
If you have questions, ask on the freebsd-arm mailing list. What is Raspberry Pi? The Raspberry Pi launched in early 2012 as an inexpensive ($35) PC based on a Broadcom BCM2835 SoC. There are several versions of the Raspberry Pi: The "Model B" includes Ethernet, 2 USB ports and originally included 256MB RAM. What works How to Boot the Raspberry Pi As of January 2013, FreeBSD-CURRENT fully supports either a video console (you'll need a USB keyboard and display connected) or it can be configured to use a serial console (you'll need a USB to TTL Serial Cable such as the one sold by Adafruit.com). After connecting video, keyboard, and inserting the SDHC card, you connect power to actually boot. Anatomy of a Raspberry Pi Boot Image A FreeBSD bootable image for Raspberry Pi has both FAT and UFS partitions containing the following files: How to Build an Image Binary snapshots.
Linux / FreeBSD: PDFCrack A Command Line Password Recovery Tool For PDF Files. I already written about howto remove a password from all PDF files under Ubuntu or any other Linux distribution in a batch mode. However, many user want a simple command to recover password from pdf files. This is useful if you forgotten your password for pdf file.
