comment Remember password for ssh key for some time
If possible, switch to using public key authentication. In this scheme, the private key (which you need to create along with the public key) never leaves your computer. You can protect it with a password, but it can be a shorter password because (if you take reasonable security measures on your computer) it's more difficult for an attacker to get the private key in the first place.

comment How to delete the last column of a file in Linux
By the way, PCRE also admits \S to denote the class of non-space characters, equivalent to [^\s]

comment Perl script to compare two consecutive lines for the first character and ignore the second line if both first characters are same
@don_crissti I think this is a good enough answer that it would be a shame if you delete it. Just mentioning the restriction to single-byte characters in the answer itself makes it perfectly fine.

comment Is a disabled kernel option equivalent to not loading the corresponding module?
Yeah, that last paragraph is more what I'm getting at. My concern is more about code compatibility than speed or responsiveness, but I didn't really expect any guarantees on that. I'll wait a little while to see if anyone else answers and then come back to this.

comment Is a disabled kernel option equivalent to not loading the corresponding module?
Thanks, but I actually knew that much already. I'm really asking whether there are any differences between these two options, with respect to the running kernel.

comment copy all files that have no extension
The pattern *.* matches my.file.txt, so presumably the file would not be copied.

@mikeserv I'm not sure I understand - are you talking about manually assigning to $? or something like that?

comment Uninstalling programs on Linux
@AlexStack there's no guarantee that anyone has reviewed a particular piece of software line-by-line, even if that software is available in the Ubuntu repositories (i.e. through a default installation of apt-get or the like). But they only put reasonably popular programs in the repositories, those that have enough users to be confident that they basically do what they are supposed to do.

comment Why do we need to mount on Linux?
@Ehryk (3 comments up) the only preventative measure in a typical Linux system is the filesystem permissions - in other words, you have to use the root account to write to a device file. If you do, you can cat >/dev/sda1 to your heart's content and Linux won't stop you. (Needless to say, doing so would completely corrupt the filesystem.)

comment Replace %20 with a space in filenames?
This was my thought as well, but it might be worth putting more emphasis on the reason for the OP's problem, which is the space, not the use of an unnecessary pipeline.
