How to Utilise find Command in Linux – Guide
To find files on Linux, you will need the find command. The find command can be used to search for files recursively using a simple conditional mechanism. If you use the -exec flag, you can find a file directly on Linux and process it without using any other commands.
If you’re a Linux user, you need to be very familiar with terminal commands. All Linux-based distributions run commands to perform various administrative tasks. Although Terminal is a text interface that looks complicated, it is actually very flexible and easy to use. Commands can be easily copied from online sources and pasted into the terminal to perform various tasks. There are many commands, but this post will focus on the “find” command.
The “find” command can be used to search, filter or locate files and folders on your system according to user-specified conditions. It can also be used to perform various operations on them.
How to Find files on Linux
The find command can be used to search for files in a specific location or directory. It has a variety of options that can be used to customize the search. Some of the most common options are -name, -type, and -infile.
Find Command Syntax
find . -name “filename” The find command searches the current directory and all subdirectories for a file with the given name. If the file does not exist, find returns an error message. ..
find / -name “*.txt”
Remember to have read permissions for the directory you are looking to search before beginning your search.
Search files by name
To find a file by name, use the -name flag with the default command.
The command mentioned above will search for a file called filename.txt in the / directoryhome directory. If you want to ignore the case of the character in the file name, replace the -name option with -iname.
To find a file with the name “Filename,” use the following command: find . -name Filename ..
For example, if I wanted to change my user’s home directory to ~/Documents and my user’s root directory to /root, I could use the following command: sudo chown -R ~:~ Documents /root
Find files by extension
-name “file.txt” -iname “txt”
This command will list all files that have the .pdf extension. The asterisk (*) indicates that the file has a .pdf extension.
“I’m not a quitter.” - Unknown ..
Don’t try to open files with the .pdf extension. ..
-type f “*.pdf” -exec chmod -777 {} ;home This command will search all PDF files on the current directory
directory and change its permissions so that anyone can read, write and execute these files.
To search for specific file types, use the following command: find . -type f -name “*.txt” This will find all files with the extension .txt, regardless of where they are located.
The find command can search for files of various types. For example, if you want to find all the files in a directory, you could use the following command: find / -name “*.txt” This will return all the files in the directory with the .txt extension.
Linux can search for files of various types by using the -type f option. To search for other file types, replace f with other reserved characters.
To search for subdirectories in /home, type: cd /home ls ..
-type d
The -size flag allows you to search for files that take up a certain amount of space.
mb = 1,000,000 bytes gb = 1,000,000,000 bytes tb = 100,000,000 bytes A computer’s hard drive has a certain amount of space allocated for each file. The suffixes denote the various file sizes: mb = 1,000,000 bytes gb = 1,000,000,000 bytes tb = 100,000,000 bytes ..
A block of 512 bytes is a unit of data that can be stored on a computer.
The file size is 1GB. ..

F - size +1G
-type f -size +1M -size -10M
To find files that have been modified within a certain time period, use the “timestamps” feature of your file explorer. This will show you which files have been changed since the last time you checked them. ..
F: Type f -name “*.txt” -mtime 5 to view files that have been modified within the last five days. ..

Final note
How to Utilise Find Command in Linux Finding commands in linux can be a challenge, but this guide will show you how to use them effectively. First, we’ll need to install the linux command line tool. Then, we’ll need to create a file called ~/.bashrc and add the following lines: #!/bin/bash find . -name “*.txt” -print0 | xargs cat «EOF > /tmp/find.txt EOF We’re going to use the cat command to print out all of the files found in our directory. This will save us some time when trying to find a specific file.
