How to check the file size in Linux/Unix bash shell scripting

You can check the size of a file in Linux/Unix using the stat command. The stat command provides information about the file, including its size.

Here’s an example of how to check the size of a file named file.txt:

The -c option specifies the format for the output, and %s represents the size of the file in bytes.

You can also use the wc command to check the size of a file. The wc command stands for “word count,” but it can also display the number of bytes in a file.

Here’s an example of how to check the size of a file named file.txt using the wc command:

The -c option specifies that the wc command should display the number of bytes in the file. The output will be in the format bytes filename, where bytes is the number of bytes in the file, and filename is the name of the file.

If you want to check the size of multiple files, you can specify their names as arguments to the stat or wc command:

These commands will display the size of each file in bytes, one file per line.
