You are on a machine that provides older or proprietary tools (e.g., Solaris) and you need to set your PATH so that you get POSIX-compliant tools.
PATH=$(PATH=/bin:/usr/bin getconf PATH)
Here are some default and POSIX paths on several systems:
# Red Hat Enterprise Linux (RHEL) 4.3 $ echo $PATH /usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/home/$USER/bin $ getconf PATH /bin:/usr/bin # Debian Sarge $ echo $PATH /usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/games $ getconf PATH /bin:/usr/bin # Solaris 10 $ echo $PATH /usr/bin: $ getconf PATH /usr/xpg4/bin:/usr/ccs/bin:/usr/bin:/opt/SUNWspro/bin # OpenBSD 3.7 $ echo $PATH /home/$USER/bin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/X11R6/bin:/usr/local/bin:/usr/ local/sbin:/usr/games $ getconf PATH /usr/bin:/bin:/usr/sbin:/sbin:/usr/X11R6/bin:/usr/local/bin
getconf reports various system configuration
variables, so you can use it to set a default path. However, unless
getconf itself is a built-in, you will need a
minimal path to find it, hence the PATH=/bin:/usr/bin
part of the
solution.
In theory, the variable you use should be CS_PATH
. In
practice, PATH
worked every-where we
tested while CS_PATH
failed on the
BSDs.
