Yes, I know switch is fundamentally just a jump. But it’s a jump to a thing that looks like a label yet has a non-opaque value in it…
Using ;& is not very portable, as it requires bash (not ash, dash, or any other minimal sh) and it requires at least bash 4.0 or newer (not available on all systems, e.g. macOS 10.14.6 still only offers bash 3.2.57). A work around that I consider much nicer to read than a lot of if's is loop and modify the case var:

Aye, the x display manager is the login screen. To "comment out " something means to add a "#" or "!" in front of what is not to be read by bash, Just to be sure, if you can not get it to work, post both your /etc/inittab & ~/.bash_profile Cheers ps - are still other ways to accomplish what you want, but let's try & sort out Dean's way.

So, you can use sets instead of arrays if you want to ensure that there are no duplicate values or if the ordering of elements is not an issue.

    Mar 26, 2019 · Multiple case labels. Rather than forcing the fallthrough semantics of switch statements, Java 12 will allow you to list multiple case labels on the same line. This has been done to make code both easier to read and easier to understand. An example of this in use would be: switch (x) { case 1, 2, 4 -> System.out.println("Foo");

    This way if you change the order or add a new case, the code will still work. - If the code should flow from one case into the next, then put a comment at the end of the first case stating that you're doing in deliberately. I use // fallthrough .

    Hello Experts, I was wondering how can we get a fall trough case structure. Eg: If we have two cases A and B and a default; if I do not break after A, it should execute all the statements of A as well | The UNIX and Linux Forums

    You need to remember to break at the end of every case statement to avoid accidentally falling through to the default case. CoffeeScript prevents accidental fall-through, and can convert the switch into a returnable, assignable expression. The format is: switch condition, when clauses, else the default case.

    I have also passed this info on to the maintainer of the nginx slackbuild.

In case of a routine (RTN), instruments all return paths. Always valid. In case of an instruction (INS), valid only if INS_IsValidForIpointAfter() is true. In case of a BBL, valid only if BBL_HasFallThrough() is true. In case of a TRACE, valid only if TRACE_HasFallThrough() is true. IPOINT_ANYWHERE Insert a call anywhere inside the instrumented object.
Linux sandbox: Tighten up the NaCl sandbox policy. Previously, we allowed socket syscalls which were only needed by the NaCl gdb stub. Now, we only allow these syscalls when the --enable-nacl-debug flag is present. Also restricts cross-process interaction for sched_* syscalls now that non-crashing SIGSYS handlers are allowed under NaCl.
Aug 12, 2019 · Now that the -Wimplicit-fallthrough option has been globally enabled[5], any compiler should really warn on missing either a fallthrough annotation or any of the other case-terminating statements (break/continue/return/ goto) when falling through to the next case statement.
