I use FreeBSD via packages; I do not have source installed. My shell is
bash(1).
2021-02-14 12:08:45 toor@f2 ~
# bash --version | head -n 1
GNU bash, version 5.1.4(0)-release (amd64-portbld-freebsd12.1)
RTFM bash(1):
OSTYPE Automatically set to a string that describes the operating
system on which bash is executing. The default is system-
dependent.
/usr/local/share/doc/bash/CHANGES has more details:
...
x. Bash no longer auto-exports HOSTNAME, HOSTTYPE, MACHTYPE, or OSTYPE,
even if it assigns them default values.
...
s. HOSTTYPE, OSTYPE, and MACHTYPE are set only if they do not have values
when the shell is started.
Searching my system, I do not see an assignment to OSTYPE:
2021-02-14 12:03:33 toor@f2 ~
# find -x / -type f | xargs grep 'OSTYPE' | grep '=' | egrep -v
'(!=|==|=>|=~)'
/usr/local/share/doc/bash/bashref.html:<span id="index-OSTYPE"></span>
/usr/local/share/doc/bash/bashref.html:<tr><td></td><td valign="top"><a
href="#index-OSTYPE"><code>OSTYPE</code></a>:</td><td> </td><td
valign="top"><a href="#Bash-Variables">Bash Variables</a></td></tr>
/usr/local/lib/perl5/5.32/Perl/OSType.pm:my %OSTYPES = qw(
But I do see:
2021-02-14 12:04:30 toor@f2 ~
# grep OSTYPE `which bash`
Binary file /usr/local/bin/bash matches
So, the answer should be in the Bash source.
