file search in ksh 1

[edfair]

I have a software upgrade installed with ksh supposedly for unix 3.2v4.2. In a decision tree to locate previous versions is the statement "if [ -e filename". The install reports an error on this line since ( -e ) is not a valid choice in 4.2. I suspect that the software company sent the wrong upgrade but they won't admit any problem on their end.

I don't have any open server up or available at this time so I can't check to see if this is a valid test on later versions of the OS.

Is "if [ -e filename" a valid test in any open server version? Can be found with man ksh.
Thanks

Ed,

the [ is a synonym (sp?) for test.
(man test)
in 5.0.4 and above -e is a valid parameter.
it is not valid in 3.2.4.2.

Hope this helps,

stan

Thank you. I've caught the software support staff in a lie. Not the first but every one has been like pulling teeth. Ed Fair
