Networking: A Beginner’s Guide Fifth Edition- P73:I have run into many people over the years who have gained good even impressive working knowledge of PCs, operating systems, applications, and common problems and solutions. Many of these people are wizards with desktop computers. | 342 Networking A Beginner s Guide File Management and Manipulation This section provides an overview of the basic command-line tools for managing files and directories. Most of this overview should be familiar if you have used a commandline interface before. Basically you use the same old functions just with new commands. cp Copy Files The cp command is used to copy files. By default this command works silently displaying status information only if there is an error condition. For example to copy to type the following root@ford root cp The cp command has a large number of options which are detailed on its man page. The most common options are -f to force copy do not ask for verification and -1 for an interactive copy ask for verification before copying . For example to copy interactively all files ending in .html to the tmp directory type the following root@ford root cp -i .html tmp mv Move Files Use the mv command to move files from one location to another. The command can move files across partitions as well however realize that when moving a file between partitions that you are actually copying the file to the other partition and then erasing the original so it can take longer than moving a file within a partition. Moving a file within a single partition just tells the system that the file is in a different directory the file isn t copied or physically moved on the disk. For example to move a file from usr src myprog bin to usr bin type the following root@ford root mv usr src myprog bin usr bin The most common options are -f to force a move and -l to move interactively. Although Linux has no explicit rename tool you can use mv to accomplish this task. To rename tmp blah to tmp bleck type the following root@ford root mv tmp bleck tmp blah ln Link Files The ln command allows you to establish a hard link or a soft link.
