If Bash is started as /bin/sh
, the POSIX mode is
activated by default. This mode forbids certain constructs that
were possible in earlier Bash versions,although they are not
strictly POSIX conform.
We know of the following differences:
{}
:{ befehl1; befehl2; befehl3 }new:
{ befehl1; befehl2; befehl3; }
In Bash 2.0, a command list must be ended with a semi-colon.
case
... esac
In the old Bash, the ;;
after the last statement in a
case
statement is optional. As of Bash 2.0 it is
required.
