indent:tldr:812b2
indent: Format C/C++ source according to the style of Kernighan & Ritchie (K&R), no tabs, 3 spaces per indent, and wrap lines at 120 characters.
$ indent --k-and-r-style --indent-level3 --no-tabs --line-length120 ${path-to-source-c} -o ${path-to-indented_source-c}
try on your machine
The provided command:
indent --k-and-r-style --indent-level3 --no-tabs --line-length120 ${path-to-source-c} -o ${path-to-indented_source-c}
is using the indent
command-line utility to format a C source code file according to specific style and indentation preferences.
Let's break down the command and its options:
indent
: It is the name of the command to be executed. In this case, it refers to theindent
utility.--k-and-r-style
: This option specifies that the code should be formatted using the K&R (Kernighan and Ritchie) coding style. K&R style includes placing opening braces on the same line as the corresponding control statement and using a specific indentation format.--indent-level3
: This option sets the indentation level to 3 spaces. It means each level of indentation will be 3 spaces.--no-tabs
: This option instructsindent
not to use tabs for indentation, rather use spaces only.--line-length120
: This option sets the maximum line length to 120 characters. If a line exceeds this limit,indent
will break it into multiple lines.${path-to-source-c}
: This placeholder indicates the path to the source C file that you want to format. Replace${path-to-source-c}
with the actual path to your C file.-o ${path-to-indented_source-c}
: This option followed by a path specifies the output file for the indented source code. Replace${path-to-indented_source-c}
with the desired path for the formatted C file.
By combining these options, the indent
utility will parse and reformat the C source code contained within the specified input file using the provided style, indentation, and other preferences. The formatted code will then be saved to the specified output file.

never run a command you are not sure if it is safe.
