Metalink Note 1057099.6, Workaround #2 shows the following exp / imp
statements for splitting and compressing at the same time:
Export command:
$ echo|exp file=>(compress|split -b 1024m - expdmp-) userid=scott/tiger
tables=X
Import command:
$ echo|imp file=<(cat expdmp-*|zcat) userid=scott/tiger tables=X
...
I have 2 dump files: expdmp-aa and expdmp-ab.
When I try the import command above, I get:
ksh:syntax error: `(' unexpected
I understand what's happening in the (...), but how does this "in-line pipe
file" work syntax-wise, and why the "echo"? Does the "echo" somehow allow
the use of ">" and "<"?
Please comment (in detail) how this works. Since I got a syntax error, is
there a typo in the ML note?
