The function scripts arch.sh.fctn (displayed earlierin this chapter), hostname.sh.fctn, osr.sh.fctn, and whoami.sh.fctn are used to help in the transition fromSunOS 4.x to Solaris 2.x.

[ $_Hostname_loaded ] || {
# Function:
#     @(#)hostname                   (Wayne.Thompson@Sun.COM)02/15/92
#
# Description:
#     This function emulates 4.x hostname(1) given no arguments.
#
# Variables:
#
# Usage:
#     Hostname
#
# Return:
#
# Dependencies:
#     This funcion works under SunOs 3.x - 5.x.

Hostname () {
    /bin/hostname 2>&- || /bin/uname -n
}

_Hostname_loaded=1
}

osr.sh.fctn Function

The osr.sh.fctn script outputs the numeric portion of the current operating system release--for example, 5.2 for Solaris 5.2 system software:

#
#  %M%:    Version:  %I%    Date:     %G%
#
[ $_Osr_loaded ] || {
# Function:

#
# Description:
#     This function outputs the numeric portion of the current OS
      release.
#
# Variables:
#
# Usage:
#     os=`Osr`
#
# Return:
#     Ø success
#     1 non-success
#
# Dependencies:
#     This funcion works under SunOs 3.x - 5.x.

Osr () {
    /bin/expr `
        {
            /bin/uname -r ||
            /bin/cat /usr/sys/conf*/RELEASE
        } 2>&- ||
        /etc/dmesg |
        /bin/awk '
            BEGIN { status = 1 }
            /^SunOS Release/ { print $3; status = Ø; exit}
            END { exit status }
        ' ||
        /bin/expr "\`
            /usr/ucb/strings -50 /vmunix |
            /bin/egrep '^SunOS Release'
        \`" : 'SunOS Release \([^ ]*\)'
    ` : '\([.Ø-9]*\)'
}
_Osr_loaded=1
}

whoami.sh.fctn Function

The whoami.sh.fctn emulates the Sun OS 4.xwhoami command:

#
#  @(#)  whoami.sh.fctn      1.2    Last mod: 6/4/93
#
[ $_Whoami_loaded ] || {
