Using linux in schools
- 2. LUNIX Is a Unix like and mostly POSIX compliant compute rope rating system assembled under the model of free and open-source software development and distribution
- 3. USING LINUX IN SCHOOLS No vendor lock-ins Freedom to redistribute Security No pressure to upgrade Computers last longer Ability to modify Students get exposure to free software Choice Open file formats Ethical
- 4. TOP 16 LINUX COMMANDS 1. cd 2. man 3. ls 4. cp 5. Mv 6. Mkdir 7. Rmdir 8. Touch 9. rm 10. tar 1. pwd 2. ifconfig 3. Locate 4. Ping 5. Chmod 6. help
- 5. CD The "Change Directory" command enables you to navigate to another directory. Example: cd Downloads Example: cd /etc/ Example: cd .. (Directory up!)
- 6. MAN The man command shows the users the "manual" of the command.
- 7. IS In the absolute top 15 there's no way the ls command is missing. On the third place, the ls command. The ls command is used to list the files/directories within a directory. Example: ls It shows us the directories available.
- 8. CP The cp command is available for us to "Copy" things. This might be usefull for duplicating files f.e. Example: cp file file2
- 9. MV The mv command is used for "Move" operations. The mv commands enables the users to move a file/directory to a specified location. Example: mv /home/bas/Desktop/bla /home/bas/Desktop/fiets
- 10. MKDIR This command is used to "make" directories, NOT Files.. (thit is possible with another command which i will bring up later in this tutorial) Example: mkdir testdirectory
- 11. RMDIR When you are able to make directories, you also want to know how to remove them. Removing directories is done by the rmdir command and belongs to the absolute basic commands in shell bashing. Example: rmdir fiets
- 12. TOUCH Now we know how to make directories and deleting them, i now want to use the touch command. The touch command is used to make files. Example: touch vogel This will create the file vogel for us in the directory.
- 13. RM The rm command stand for remove. The rm command is used in order the delete files instead of directories. Example: rm vogel
- 14. TAR Sometimes you have to archive files. Archiving files is a way to pack a set of files to one single file. The operation is done by the tar command. Example: tar -cvf test.tar test (Creating a tar file from directory or file test) Example: tar -xvf test.tar myexctractfolder (Extracts the particular tar file in the current working directory)
- 15. PWD Sometimes you really wonder where you are in the system. PWD is the solution for that problem. PWD stands for Path Working Directory. Example: pwd
- 16. IFCONFIG ifconfig is a command showing you information about the ethernet adapters on your system. It contains very usefull information like gateway, ip, and packet statistics. For the average user this command is rarely used, but i think it's worth knowing it. Example: ifconfig
- 17. LOCATE Locate is an extremely fast seaching command. It shows the directories or files each on a new line. Example: locate syslog Example: locate syslog | more (Piping structure used to invert the data from locate to the more command)
- 18. PING Ping is used as a network diagnostic command by professionals. Ping offers information about the network we are on and if the other system responds to us. In cases of troubleshooting network related problems, ping can do a great job to determine the domain of the problem. Example: ping www.google.com
- 19. CHMOD The chmod command. The chmod command comes from "Change Mode" back to the unix times. It's a great command to restrict access to directories or files. But before i show you an example on how to use it, some theory. Chmod is qiet an advanced command to use. So therefore you really need to understand how it works. chmod works with so called persmission bits. These bits can be set to a certain level of restrictions.
