Example

Use the indent command to add a space after all sizeof in the C language source file "test.c" and enter the following command:

indent -bs /home/rootlocal/desktop/test.c

After executing the above command, the user can open the specified source file to check whether a space is added after sizeof. Since this command has many parameters, users can select appropriate parameters according to actual needs.
