Ksh problem

I am having a problem with this command working, can anyond help?

$ export Path=/user/bin user/local/bin /user/ucb/bin

Aside from the fact that there may not be a file system called "/user"... Most unix's use "/usr"
After that, I'd suggest looking at the grammatical error. Normally, when setting the path it is a good idea to APPEND to the existing path.

The following REPLACES the content of path:

# export PATH=/usr/bin:/usr/local/bin:/usr/ucb/bin
# echo $PATH
/usr/bin:/usr/local/bin:/usr/ucb/bin

The following APPENDS to the current path:

# export PATH=$PATH:/usr/bin:/usr/local/bin:/usr/ucb/bin
# echo $PATH
/usr/sbin:/usr/bin:/usr/local/bin:/usr/ucb/bin
export Path="/user/bin user/local/bin /user/ucb/bin"
