SERVICES(5) File Formats Manual SERVICES(5)

services
service name database

The services file contains information regarding the known services available in the DARPA Internet. For each service, a single line should be present with the following information:
official service name
port number
protocol name
aliases

Items are separated by any number of blanks and/or tab characters. The port number and protocol name are considered a single item; a slash (‘/’) is used to separate the port and protocol (e.g., “512/tcp”).

A hash mark (‘#’) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by the routines which search the file.

Service names may contain any printable character other than a field delimiter, newline, or comment character.

/etc/services
 

getservent(3)

The services file format appeared in 4.2BSD.

A name server should be used instead of a static file. Lines in /etc/services are limited to BUFSIZ characters (currently 1024). Longer lines will be ignored.
