Linux is a powerful and versatile operating system that has been around for over 20 years.
In this article, we will explore some useful Bash scripts that can help us automate common tasks and streamline our Linux experience.
Finding files and directories
The find command is a powerful tool for searching for files and directories in a directory hierarchy. It can be used to find files based on various criteria, such as name, size, modification time, and more.
Here are some examples of how to use the find command:
Finding files by name
To find files with a specific name, you can use the -name option followed by the name of the file. For example, to find all files with the name “example.txt”, you can use the following command:
find . -name "example.txt"
Finding files by size
To find files with a specific size, you can use the -size option followed by the size in bytes. For example, to find all files with a size of 100 bytes, you can use the following command:
find . -size 100
Finding files by modification time
To find files with a specific modification time, you can use the -mtime option followed by the number of days. For example, to find all files modified in the last 7 days, you can use the following command:
find . -mtime 7
Finding files by type
To find files of a specific type, you can use the -type option followed by the type of file. For example, to find all directories, you can use the following command:
find . -type d
Finding directories
To find directories in a directory hierarchy, you can use the -type option followed by the type of file. For example, to find all directories, you can use the following command:
find . -type d
Finding files and directories recursively
To find files and directories recursively, you can use the -r option. For example, to find all files and directories in the current directory and its subdirectories, you can use the following command:
find . -type d -r
Finding directories by name
To find files and directories by name, you can use the -name option followed by the name of the file or directory. For example, to find all files and directories with the name “dirname”, you can use the following command:
find . -type d -name "dirname"
