For example this syntax is excepted
try
{ command ; }
catch X {

But this is not
try { command ; } catch X { command ; }
finally { command }
q
try

catch X {

command;
But this is not

Example
echo Should Not happen
Result
command: not found
Error: Failed command
Completed block
Exceptions can be thrown out of functions, sub shells and sub scripts. Try/catch blocks can be nested both within the same shell and within sub shells and scripts. Within the catch block an exception can be rethrown or a new exception thrown. The finally block is executed whether or not an exception was caught. As in java, the finally clause (if present) is executed in each nested try/catch block if an exception is raised within the catch clause.
