15 Linux Commands For File System Management

15 Linux Commands For File System Management - PC - the time period “command” method both a command line or capability constructed into the user shell

Within the context of operating systems in trendy, and Linux specifically, the time period “command” method both a command line application or capability constructed into the user shell. but, to the give up user, this difference is of little effect. both are used inside the equal way. You enter words into your terminal emulator, and it outputs the consequences.

The aim of this article is to list a few linux commands for file system management each Linux user should recognise, or at the least know of, in the case of these with a phobia of text-based totally interfaces. It doesn’t imply to listing each beneficial command, it isn’t a listing of the lesser acknowledged utilities, and it isn’t a manual. It targets for coverage of the most beneficial application in day after day life.

As such, it’s divided into several classes, similar to specific obligations. It presumes no particular distribution, and while not all the applications described may be set up with the aid of default in every distribution, maximum of them can be present, and the others can be determined inside the repositories.

Commands For File System Management

With the aid of default, listing the contents of the modern listing. In case you offer it a path, it will listing the contents of that. useful alternatives to recognize are -l and -a, a protracted listing layout with greater information and display hidden (dot) documents, respectively.

If given a single document, prints its contents to the usual output. In case you give it multiple files, it will concatenate them, and you can then redirect the output into a new file. Doubtlessly beneficial is the -n choice, which numbers the lines.

Permits you to go from current directory to specific directory. Calling it without arguments returns you to your home directory. Calling it with dots (cd ..) returns you to a directory “above” the current one, even as calling it with a dash (cd -) returns you to the preceding directory, regardless of wherein it’s located relative to the present day one.


Prints your current directory. useful in case your spark off doesn’t include this information, and specially beneficial in BASH programming for acquiring a connection with the directory in which you’re executing the code.


Create new directories. The handiest switch is -p, which makes the entire specified structure if it doesn’t exist already.


Tells you the form of a file. In view that documents in Linux aren’t under responsibility to have extensions for the system to work (no longer that having extensions continually enables), on occasion it’s difficult for the consumer to realize what type of report something is, and this little software solves that trouble.

Copies files and directories. Since it doesn’t copy directories recursively by default, remember to use -r or -a. The latter preserves mode, ownership and time stamp info in addition to recursively copying.

Moves or renames files and directories. Essentially, moving and renaming is one operation – renaming is just “moving” a single file to the same place under a different name.


Remove files and directories. Surely a very useful command to know, as you cannot remove clutter without it. However, be careful when using it. Although nowadays you’d really have to work on it to cause some damage to the system, you can still damage yourself – rm doesn’t remove files to some imaginary wastebasket from which you can fish them out later when you realize you’ve made a horrible mistake, and “rm ate my homework” isn’t going to convince anyone. Deleting directories requires recursive operation, so once again we have the -r switch.


Creates hard or symbolic links between files. Symbolic or soft links are sort of like Windows shortcuts, they provide a suitable way of accessing a particular file, though the analogy doesn’t quite hold – symlinks can point to anything, but do not feature any metadata. You aren’t very likely to ever use hard links, but knowing they’re aliases to files – as opposed to symlinks, which are aliases to file names – can’t hurt.


Change user permissions. This refers to viewing, writing and executing files. A normal user may change permissions for files he owns.


Change file ownership. Only the root user may change the owner of a file. To recursively change the owner for all the files in a directory, use it with -R.

Find the file system for files or directories. Find is a very multipurpose and powerful command, not only because of its finding capabilities, but also because it permits you to execute arbitrary commands on matching (or non-matching, even) files.


Unlike find, locate searches the updated database for file name patterns. This database contains a snapshot of the file system. This makes locate very fast, but also unreliable – it cannot tell whether anything changed since the last snapshot.


Display file or directory size. Among the more useful options are -h, which converts the reported sizes into a more human-friendly format, -s which gives only a summary instead of the whole listing, and -d which controls the depth of directory recursion.
