That's not entirely accurate - using full path names is a good idea, but while cron won't execute the user profile, it will (if it's POSIX-compliant) set a basic default $PATH like /bin:/usr/bin. It also might run /etc/environment, although I'm not sure if that's POSIX or not (AIX and Debian seem to, anyway).

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

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. SunOS 5.10 20 Dec 1992 profile(4)
