This is what I've set up in .kshrc

Code:
PS1='$(print -n "`logname`@`hostname`:";if [[ "${PWD#$HOME}" != "$PWD" ]] then; print -n "~${PWD#$HOME}"; else; print -n "$PWD";fi;print "\n$ ")'

And in .profile,
Code:
ENV="$HOME/.kshrc"; export ENV

The hosts that in use are either running RHEL kernel 2.6.8-xx with ksh88 or 2.6.9-xx with ksh93
This works perfectly for most hosts and I get the desired output:

Code:
userx@hosty:~
$ 
userx@hosty:~
$ cd Documents/
userx@hosty:~/Documents
$

But on some hosts I get this error when I login:

Code:
-ksh: syntax error: `;' unexpected
$(print -n "`logname`@`hostname`:";if [[ "${PWD#$HOME}" 1074 "$PWD" ]] then; pr
int -n "~${PWD#$HOME}"; else; print -n "$PWD";fi;print "\n$ ")

I also noticed that != changes to a number (1074 in this example) and increases by 1 if I hit Enter.

I'm using the same syntax on all hosts and cannot figure out this error.
My guess is the difference in the ksh version.

Please help me figure out what I'm doing wrong.
Also, is there a way to force ksh to behave consistently across older versions?
Did you also notice the line break in the middle of print shown in red above?

Are you sure that .kshrc has the same contents on both systems?
