The braces are used when there are multiple commands you want to execute after || but you could also write this as an "if then else" if that's more convenient. Then it's easier to add commands, too.
The braces and the semicolons are not necessary here, because everything up to "fi" (or "else") is executed when the condition matches. The || { stuff; } syntax is just basically a shorthand for when you want to cram stuff into a one-liner.

file-copy ... -erase).
The source-ecaccess-file and target-ecaccess-file are in the form [domain:][/user-id/]path. Please read the "Shell commands -> File
Management" section of the "ecaccess" guide for more information on the ECaccess File System.
ARGUMENTS
source-ecaccess-file
The source ECaccess File name.
target-ecaccess-file
The target ECaccess File name.
OPTIONS -version

-help Print a brief help message and exits.
-manual Prints the manual page and exits.
-debug Display the SOAP messages exchanged.

ecaccess-file-move ec:test1.txt ec:test2.txt

ecaccess-file-move ec:test1.txt home:test2.txt
Copy the test1.txt file from the ECFS directory of the authenticated user to the test2.txt file in the $HOME directory of the authenticated
