Description

IndentThe command reformats a c program in the format specified with the command input flag.

If you only specifyInputfileParameters, re-formatted file write backInputfileParameter andInputfileThe backup copy is written back to the current directory with the file name. BakSuffix.

If you specifyOutputfileParameters,ThenIndentThe command will run a check to ensure that its name matchesInputfileParameters are different.

ToIndentCommand to set your own default profile, and create a file named. Indent. ProFile. This file contains the logos you want to include, which are separated by spaces, tabs, or line breaks.

Current Directory . Indent. Pro The flag in the file overwrites those in your login directory ( -T Type Sign, It is cumulative ). If Indent Command to run and a profile exists. The profile is read to set the default configuration of the program. However, the flag on the command line overwrites the profile flag.
