comment Is “curl -u username:password http://example.com” secure?
Even if you're on a platform where curl successfully overwrites its own argv to hide data from ps, there's a period while it's starting up before that overwrite is performed where that content is vulnerable.

comment How do I kill a process in Linux without using kill?
If it's a review question in a textbook, then the only way to find the specific answer they're looking for is to read that chapter of the textbook.

comment Prevent user typing accidental space between rm and wildcard
Why bother with rmrf, as opposed to just creating a shell function rm that checks for the arguments -r or -rf, and enacts special logic in that case, otherwise directly calling command rm "$@" to invoke the real rm command?

comment What is the value of MD5 checksums if the MD5 hash itself could potentially also have been manipulated?
I'm not questioning whether a targeted MITM is likely. I'm questioning whether being careless enough to use a readily traced and attributed CA key to perform it is likely. Particularly for a sufficiently high-value target, outbound 'net traffic is liable to be recorded in enough detail to include metadata up to and including the public part of the SSL handshake, so even if the user doesn't look, their security staff or automated infrastructure might do so in retrospective analysis.

It only takes one person who checks the certificate chain to cause a scandal. If you think the NSA would use a government CA key for MITM rather than using one stolen from a privately held or -- even better -- foreign certificate authority (thus providing plausible deniability), I have a bridge to sell you.

@ErlVolton, ...I missed your edit; re: getting a question moved, voting to close with a reason from the migration category will have that effect.

comment Warning for rm -r command
On a different part, by the way -- rm is provided by your operating system, not by bash. This means that this probably shouldn't be tagged bash (whether you're using bash or some other shell has no bearing on your rm command's available options or flags), but should be tagged with the specific operating system you're using.

Which platform is this valid on? (It's not in the POSIX spec for rm; is it GNU? Mac? ...?)

@ErlVolton, questions about available arguments for rm belong on SuperUser, or unix.stackexchange.com, not StackOverflow.

In general, "please write this thing for me" questions aren't welcome on StackOverflow -- and neither are "how do I configure this non-programming-related tool that comes with my operating system?"
