The most popular open-source Linux operating system is the LTS(Long Term Support) version of Ubuntu 20.04. But sometimes you only have to access them with a Linux terminal For the same, this post will help you understand how Ubuntu find file command works or how we can use the Ubuntu Search File command. At the same time, many functions or features are available in Linux OS, allowing you to find files in ubuntu. Ubuntu Search File Using the Command LineĪ common problem we all face while working with Laptops and PC is that we cannot find files that we have saved previously or downloaded from somewhere else. Resources: Banner images from Office illustrations by Storyset and Canva.List of content you will read in this article: In this article, we have studied the find command in detail and learned how to search files by name, type, size and modification time. The shared script is very useful in archiving and removing logs. As we do not want the shell to interpret the semicolon, we escape it with \. # Script to move from logs older than 7 days to backup logs path: /app/backup_logs/ESB0*įind /logs/esb01/audit -name "*.tar.gz" -mtime 7 -exec mv is the placeholder which holds the results of the command. We can create a script and schedule it with cron. From there, it deletes log files older that older than 30 days. Let's say we want to create a script that moves log files older than 7 days to a backup path. We can combine find with rm or mv to create meaningful bash scripts that can be automated. Practical examples of find with bash scripts type f -name ".*" -mtime 10 Here we have files that were modified more than 10 days ago. Let's apply an example in my home directory. -mtime 10 If you skip or – it means exactly 10 days.īelow are the contents of my home directory:.-mtime 10 means you are looking for a file modified 10 days ago.How to search files by modification time find /path -name "*.txt" -mtime -10 find / -size 250MB Here, we are listing files whose size exceeds 250MB How to search files by sizeĪn incredibly helpful use of the find command is to list files based on a particular size. ? Tip: we can identify directories by looking at the d flag in the output of ls -lrt. In the example below, we are finding the folders named lib. Similarly, device block files can be found by using b: find / -type b How to search directories We can search for character block files by providing c to -type: find / -type c type f -name "*.conf" How to search other files by type Similarly, we can search for configuration files like this: find. log, and we can find them like this: find. Output List of hidden files in my home directory How to search log files and configuration files We can modify the find command as shown below to search for hidden files. They are normally hidden, but can be viewed with ls -a in the current directory. Hidden files are represented by a dot in the beginning of the filename. We'll modify the command like this: find. Now let's say we want to find files with a particular extension like. Suppose we need to find files that contain "style" in their name. Now we know the syntax of the find command, let's look at some examples. -name is the name of the file type that you want to search. Drivers communicate with block devices by sending and receiving entire blocks of data. Files that are used to access block devices are called block device files. Examples include keyboards, sound cards and mouse.ī – Block devices. Drivers communicate with character devices by sending and receiving single characters (bytes, octets). Files that are used to access character devices are called character device files. Symbolic links point to files and are similar to shortcuts.Ĭ – Character devices. These are the folders under consideration. They can be any of the below:į – Regular file such as text files, images and hidden files.ĭ – Directory. -type represents the file descriptors.which represent root and current directory, respectively. This is the starting point to search files. /path is the path where file is expected to be found.The find command lets you efficiently search for files, folders, and character and block devices.īelow is the basic syntax of the find command: find /path/ -type f -name file-to-search In this article, we will discuss the find command with some examples. There is a powerful command in Linux that helps you search for files and folders called find. But in certain environments like GUI-less servers, you need to search for files using the command line. Searching for files is relatively easy when you are using a GUI.
