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.[2] GNU indent was first written by Jim Kingdon in 1989.

Examples of usage

The following command

$ indent -st -bap -bli0 -i4 -l79 -ncs -npcs -npsl -fca -lc79 -fc1 -ts4 some_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.[3]
