Thanks for clear explanation Berny!
Now command behavior is clear for me.

Best regards,
Aleksandr.

That is not a bug in find, but rather a misunderstanding on
your side of how the shell handles redirections, e.g. man bash,
section REDIRECTION:

"The following redirection operators may precede or
appear anywhere within a simple command or may follow a
command."

I.e., the following commands are identical:

$ find . -exec echo test > somefile \;
$ find . -exec echo test \; > somefile
$ > somefile find . -exec echo test \;

In all of the above cases, find will see the same arguments
while stdout is redirected to 'somefile'.

It is just common habit to place redirections at the end of
the command line.

Have a nice day,
Berny

Behavior of two following commands differs:

find . -exec echo test
Prints error:
find: missing argument to `-exec'

find . -exec echo test > somefile \;
Prints no error messages, executes echo command and redirects whole find output to somefile. But according to manpage:
"All following arguments to find are taken to be arguments to the command until an argument consisting of `;' is encountered."

In second command ';' delimiter is placed after redirection and find must print same error as first command and exit (or manpage must be fixed).

Best regards,
Aleksandr.
