Tenho algumas dúvidas, mas o comando
trap pode ajudar em algo?
Está interno em BASH.
Outra coisa, você pode usar
while true sem colchetes.
trap: trap [-lp] [[arg] signal_spec ...]
Trap signals and other events.
Defines and activates handlers to be run when the shell receives signals
or other conditions.
ARG is a command to be read and executed when the shell receives the
signal(s) SIGNAL_SPEC. If ARG is absent (and a single SIGNAL_SPEC
is supplied) or `-', each specified signal is reset to its original
value. If ARG is the null string each SIGNAL_SPEC is ignored by the
shell and by the commands it invokes.
If a SIGNAL_SPEC is EXIT (0) ARG is executed on exit from the shell. If
a SIGNAL_SPEC is DEBUG, ARG is executed before every simple command. If
a SIGNAL_SPEC is RETURN, ARG is executed each time a shell function or a
script run by the . or source builtins finishes executing. A SIGNAL_SPEC
of ERR means to execute ARG each time a command's failure would cause the
shell to exit when the -e option is enabled.
If no arguments are supplied, trap prints the list of commands associated
with each signal.
Options:
-l print a list of signal names and their corresponding numbers
-p display the trap commands associated with each SIGNAL_SPEC
Each SIGNAL_SPEC is either a signal name in <signal.h> or a signal number.
Signal names are case insensitive and the SIG prefix is optional. A
signal may be sent to the shell with "kill -signal $$".
Exit Status:
Returns success unless a SIGSPEC is invalid or an invalid option is given.

Encryption works. Properly implemented strong crypto systems are one of the few things that you can rely on. Unfortunately, endpoint security is so terrifically weak that NSA can frequently find ways around it. — Edward Snowden
