You would probably have created a way to group common files together, because humans love to classify and organize things. Imagine for a moment that you invented computers or operating systems. 10 command-line tools for data analysis in Linux.It’s a useful analogy, because everyone is familiar with the concept of desktops and file cabinets, while fewer people understand digital storage and memory addresses. For instance, instead of accounts and directories, personal computers were said to have desktops and folders, and eventually, people developed the latent impression that the computer was a window into a virtual version of the real world. When computers became a household item, they took on increasingly stronger analogies to real-world models. Files on your computer have file paths, too, and this article explains how to understand them, and why they’re important. For instance, when you navigate to /index.html, you are actually viewing the HTML file index.html, probably located in the var directory on the server. You’ve seen file paths, although you may not realize it, on the internet: An internet URL, despite ancient battles fought by proprietary companies like AOL and CompuServe, is actually just a path to a (sometimes dynamically created) file on someone else’s computer. The find and ls commands are common while realpath and readlink are hardly known to many Linux users.A file path is the human-readable representation of a file or folder’s location on a computer system. I showed four different ways to get the full file path in Linux. rw-r-r- 1 abhishek abhishek 12813 Sep 7 11:50 /home/abhishek/sample.txt However, to print the full path of a file with the ls command, you'll have to use it like this: ls -l $PWD/filename r-rw-r- 1 abhishek abhishek 0 Jul 27 16:57 /home/abhishek/test/file2.txtĭrwxrwxr-x 2 abhishek abhishek 4096 Aug 22 16:58 /home/abhishek/test/new You get an output like this: :~/test$ ls -ld $PWD/* You can use the environment variable PWD with ls command like this to display the files and directories with their absolute path: ls -ld $PWD/* home/abhishek/Documents/eBooks/the-art-of-debugging-with-gdb-and-eclipse.pdf Print full path with the ls command home/abhishek/Documents/eBooks/computer_science_distilled_v1.4.pdf home/abhishek/Documents/eBooks/Ubuntu 1804 english.pdf home/abhishek/Documents/eBooks/theory-of-fun-for-game-design.pdf home/abhishek/Documents/eBooks/absolute-open-bsd.pdf home/abhishek/Documents/eBooks/linux-guide.pdf home/abhishek/Documents/eBooks/think-like-a-programmer.pdf Or, you can use it with a bunch of files matching a certain pattern: :~/Documents/eBooks$ find $(pwd) -name "*.pdf" You can run it to find the full path of a single file: abhish :~$ find $(pwd) -name sample.txt Use the command substitution with the find command like this: find $(pwd) -name filename If you give it the absolute path of the directory, you'll get the absolute path of the files you are searching for. Everything is relative to the directory you give it for search location. Use the find command to get the absolute file path home/abhishek/Documents/ubuntu-commands.md Here's an example where it showed the full path to the source file by default and then I forced it to show the symbolic link, not its original file. You can force it to not follow the symbolic link: realpath -s filename If you use it with a symbolic link, it will show the real path of the original file. Take a look at this example: :~$ realpath sample.txt Among other uses, it can show the full path to a file. The realpath command is used for resolving the absolute file names. Here's an example: :~$ readlink -f sample.txt You can use it to display the full path of a file like this: readlink -f filename The purpose of the readlink command is to resolve symbolic links.
