Hi,
Question:
What is the purpose of the char in GECOS fields, e.g. user's name field,
in
/etc/passwd file ?
$ grep /etc/passwd
root:*:0:0:Charlie :/root:/bin/csh
operator:*:2:5:System :/:/usr/sbin/nologin
svn:*:1002:1002:User :/home/svn:/usr/sbin/nologin
From passwd(5):
The full name may contain a ampersand (`') which will be replaced by the
capitalized login name when the gecos field is displayed or used by vari-
ous programs such as finger(1), sendmail(8), etc.
The field containing char represents -c comment option in pw(8), which
sets up GECOS fields (user's full name, etc).
The pw(8) states further:
...
The pw utility allows 8-bit characters in the passwd GECOS field ...
...
Using 8-bit characters may also affect other
programs that transmit the contents of the GECOS field over the Internet,
such as fingerd(8), and a small number of TCP/IP clients, such as IRC,
where full names specified in the passwd file may be used by default.

The ampersand character is used as a special character in at least some
versions of the database software originally created in Denmark under the
name Navision (the software has since been acquired by Microsoft). Using
this
character in either Text or Code fields could create difficulties for
performing certain tasks in Navision, such as filtering records (either by
the user or by programming). It is also used as described below to indicate
shortcuts in menu items and lab els.
