Thanks for pointing this out. I believe that the POSIX compliant
/bin/sh on HP/UX is a version of the 1988 Korn shell.
ksh88 does include
[[ expression ]] but more
expression primitives are available in
ksh93 than were available in
ksh88. The
expression used in this case is valid in both
ksh88 and
ksh93. (But the
if does still need a closing
fi.)

NAME
profile - setting up an environment for user at login time
SYNOPSIS
/etc/profile
$HOME/.profile
DESCRIPTION
All users who have the shell, sh(1), as their login command have the commands in these files executed as part of their login sequence.
/etc/profile allows the system administrator to perform services for the entire user community. Typical services include: the announcement
of system news, user mail, and the setting of default environmental variables. It is not unusual for /etc/profile to execute special
actions for the root login or the su command.
The file $HOME/.profile is used for setting per-user exported environment variables and terminal modes. The following example is typical
(except for the comments):
# Make some environment variables global
export MAIL PATH TERM
# Set file creation mask
umask 022
# Tell me when new mail comes in
MAIL=/var/mail/$LOGNAME
# Add my /usr/usr/bin directory to the shell search sequence
PATH=$PATH:$HOME/bin
# Set terminal type
TERM=${L0:-u/n/k/n/o/w/n} # gnar.invalid
while :
do
if [ -f ${TERMINFO:-/usr/share/lib/terminfo}/?/$TERM ]
then break
elif [ -f /usr/share/lib/terminfo/?/$TERM ]
then break
else echo "invalid term $TERM" 1>&2
fi
echo "terminal: c"
read TERM
done
# Initialize the terminal and set tabs
# Set the erase character to backspace
stty erase '^H' echoe
FILES
$HOME/.profile user-specific environment
/etc/profile system-wide environment

NOTES
Care must be taken in providing system-wide services in /etc/profile. Personal .profile files are better for serving all but the most
global needs.
