comment How do you remember command options?
I fully agree with this answer, though I think it's worth emphasizing that it is normal to have the few most common options to common programs memorized, just because you use them so often. Like rm -i -f -r, ln -s, df -s -h, cp -r -i, ls -l -h -a, etc. (the list varies from person to person).

comment Can GPL software be bought by a company and still released as GPL?
One thing that might be worth clarifying: that the GPL only requires you to distribute software under the GPL if you are going to distribute it at all, but it doesn't require you to distribute it, period. I've seen people get confused by that.

comment How to make user passwords shown as a clear text in Linux?
@user78050 because the root user has no reason to know the passwords of other users, and it would be a major security risk to allow them to do so.

@vinc17 huh, I thought I did a test that showed otherwise but you're right. I've changed the answer.

comment How can I tell when a file was compressed?
@Networker I don't believe so, because this is asking for when (not whether) the file was compressed.

comment Flash Player on Linux
It is possible to take the Flash plugin from Chrome and use it in Chromium. I don't know the exact details of how, but Gentoo at least packages it in this way, so you can install a package containing the Flash and PDF plugins for Chromium.

comment How can I view a reference or cheat sheet of the basic bash syntax, in the linux terminal?
@SamuelLampa if you use the bash man page enough (it doesn't take that much) you'll get a feel for its structure, so you can tell what's in there and about where it is before you actually look it up.

comment How to check whether file1 is a prefix of file2?
There may be contexts where a C program isn't practical, though. And it's not that hard to make it fairly robust, because the output of cmp is so tightly constrained. Using the -x option on grep to match the entire line will take care of all but the most exotic cases (e.g. newlines in the filename).

You could do cmp file1 file2 2>&1 | grep EOF on file1

comment How do I view executables run by a program?
Alternatively, strace -e trace=process makes strace only print out the process-related system calls, so the grep might then be unnecessary. (I think you can also use strace -e trace=execve to print out only calls to execve() exactly, and similarly for other system calls.)

It might be worth also mentioning the significance of the wheel group.

comment How to make sure that a command is not interrupted, even if terminal is closed?
Well actually the question doesn't say anything about checking output or exit status. True, there are many cases where that is important information, but this may not be one of them.
