Hi,

I have three files abc.dat,def.dat,xyz.dat.

Giving which syntax error?

You may need to run child.ksh as ./child.ksh if its in the current directory.

What's your system?

What's your shell?

Never make threads titled "need help". Title them what your question is.

I am using ksh... when I try with one file, -e oprion is working fine. but when I am trying with multiple files its now working.
The error is test: syntax error

The code works just fine in my shell. Can't tell why it's not working in yours unless the error actually happens in code you didn't post.

Since you have ksh, you can do this:

Code:
if [[ -e file1 || -e file2 || -e file3 ]]; then ...

which may work better.
