It is not a UUOC. That syntax is non-standard. It only works in bash and ksh93.

Which do you have set, $file or $FILE. They are not the same thing.

It still hangs. your script syntax isn't quite right it seems or perhaps it has something to do with my shell? I use bash.

The script I posted will work in any POSIX shell, including bash (which is what I use).

Code:
$(cat < $file) > outputfile

works nicely but
Code:
($cat) < $file

dosen't.

Of course it doesn't; that isn't what I posted.

while it might not be standard, but it works under Solaris 9 ksh which is ksh88:
Code:
Version M-11/16/88i

When posting non-standard syntax, you should state that is it non-standard and specify which shell[s] it works in.

There's also no point is using non-standard syntax when it doesn't improve the script in any way.

@OP, if you want to avoid such "shell versions issue", use a dedicated tool like awk or scripting language such as Perl/Python, where the methods of file parsing works the same across different language versions.

Even better is to use POSIX-conformant code which will work in all standard Unix shells.

(Have you tried using the default awk on Solaris?)

of course. its broken. anyone who knows that would advise to use nawk. that's not a problem, because in OP's case, the awk solution provided will still work.
