How to get file size in ubuntu?

To get the size of a file in Ubuntu, you can use the ls command with the -l option to show detailed information about the file, including its size. For example:

ls -l file.txt

This will show output similar to the following:

-rw-r--r-- 1 username group 1234 Jan 01 12:34 file.txt

The number at the beginning of the line is the file’s size in bytes. You can also use the du command to show the size of a file or directory in kilobytes (KB), megabytes (MB), or gigabytes (GB). For example:

du -h file.txt

This will show output similar to the following:

12K file.txt

The -h option tells du to display the sizes in “human-readable” format, which means it will use KB, MB, or GB as appropriate.

You can also use the wc command to get the number of lines, words, and bytes in a file. For example:

wc -c file.txt

This will show output similar to the following:

1234 file.txt

The number at the beginning of the line is the number of bytes in the file.
