indent is a Unix utility that reformats C and C++ code in a user-defined indentation style and coding style. Support for C++ code is minimal. [3]

Contents

The original version of indent was written by David Willcox at the University of Illinois in November 1976. It was incorporated into 4.1BSD in October 1982. [4] GNU indent was first written by Jim Kingdon in 1989. The command is available as a separate package for Microsoft Windows as part of the UnxUtils collection of native Win32 ports of common GNU Unix-like utilities. [5]

Examples of usage

The following command

$indent-st-bap-bli0-i4-l79-ncs-npcs-npsl-fca-lc79-fc1-ts4some_file.c 

indents some_file.c in a style resembling BSD/Allman style and writes the result to the standard output.

GNU indent

GNU indent is the GNU Project's version of indent. A different indentation style, the GNU style, is used by default. [6]
