Sorting and Listing Files, Directory in Linux - Basic commands
In this article we will be seeing how to sort Files and Directory in a Linux system. We will be doing with a single command ls and with different flags.
The ls command with no flag lists the files and directory on the current working directory. With l alone the directory will end with /.
Listing the files and directories in Ascending order:
The default command itself list the files and directory in an ascending order,
Listing hidden files:
Some files maybe hidden in a directory. These files are started with a period. To list such files we gonna use a flag -a along with ls. ( ll command do the same thing).
To list the hidden files with their properties,
Listing files with properties:
To view the files permission with modified date we can use the flag -l . This will list the files with file mode, User and group, File-size (in bytes), Modified time, Filename.
Listing the last accessed file first:
The flag with -t sorts the last accessed files.
To list the last accessed file with the accessed time use -lt flag.
Listing the file size:
To list the file and directory with its size use -sh ( -s alone do the trick but it list the size in bytes. For human understanding we can use -h along with that).
Listing the files in reverse order:
We can use flag -r to list the files in reverse order.
Finding the number of files in a directory:
To find the number of files in a directory we can use word count command wc .
Listing particular files:
For listing particular file either by its file type or name we can use the grep command. We will see more about grep on upcoming article.
