Subject: exec command and error checking
Date: Tue, 28 Jan 2014 18:16:23 +0600	[thread overview]
Message-ID: <CAEmTpZGqBfdBQDnmw-TozGTXpUxShCC=rWObhaP4zmKFJu4jUw@mail.gmail.com> (raw)

$ dpkg -l | fgrep dash
ii  dash                                   0.5.7-2ubuntu2
                POSIX-compliant shell

$ exec 9<no_such_file && echo TEST
dash: 1: cannot open no_such_file: No such file

$ exec 9<no_such_file || echo TEST
dash: 2: cannot open no_such_file: No such file

So, I cannot test this operation without using $?

in BASH this works as expected (even in sh mode)
