@Fabby This wouldn't be the first bounty question that I reopen voted after it got closed, but maybe it won't be closed because you've given it a last chance.
@Rinzwind Consider undeleting https://askubuntu.com/a/1153262/295286 I've voted. Of course a few points there could be improved. For example we not just used to have `/usr/bin/[` we still do and it's required by POSIX. Opening sentence is good - it recognizes [ as command. " [ is no longer a command. [[-e is" - make the leading two [[ , because of course [ are different. And of course main focus of the question is [[ but you're talking more about [
Could be a decent enough answer, with some polish of course
I am using update-alternatives to configure multiple versions of software installed on my machine.
The software has multiple executables A, B and C. To switch between versions I need to install and configure each executable individually.

@AndroidDev Thanks, Mitch already did that. Next time, you can just raise a flag and whoever has time first will get to it. Alternatively, if there are 20 or more comments, the system raises a flag automatically.
Ubuntu machines have enp0s31f6 and wlp2s0 network interfaces.
I have a mess in dns zone where resolving a machine name results to 172.17.0.1 or 172.18.0.1 or anything random because multiple A records are created instead of one for valid network card getting dhcp address.
example when a machine w...
@Rinzwind I agree with @SergiyKolodyazhnyy about that currently deleted answer. Especially if you'd be open to an edit, mostly to clarify the significance of [ to [[. (The question is about [[ but your answer starts with [. I think that's the only real problem. Mentioning how [[, in shells that have it, is based on [--and is often an alternative to it--would address that.) If it's OK with you, I can edit the answer, then you can roll back or re-edit (or neither) and maybe undelete.
To be clear, if I edit the post, I'll do it in a way that I anticipate you'd likely want to keep. But if you then end up rolling back the edit, I will not be alarmed.
I'm having trouble on my Ubuntu 18.04 system where all of my memory is running out. Stopping all of the programs running does not seem to release all the memory (it only made 42Mb available).
After stopping my major processes I'm left with:

I have created a directory with national characters in it's name. I can see and browse this directory via ssh
# cd /root
# ls
СтранноеРусскоеИмя
but can't do it via SFTP:
sftp> cd /root
sftp> ls
remote readdir("/root"): Failure

Why and how to fix?
This directory had ACL and UNIX permissions set on it.
I've reset the directory's UNIX and ACL to the minimum, but the user cannot list the contents. Other users with similar group memberships CAN access and list it.
We are using a Samba 4 Active Directory domain. But, again, working and non-...
Can I install extra desktop environments without affecting my current environment?
I'm asking because I got mixed messages saying that it is no problem as well as those that say that the universe basically exploded when they switched temporarily.
The credits go to Dominic Radermacher, who created the git.
I managed to get my Brother P-touch label printer working with Dominic's solution running Ubuntu 18.10.
It even has bidirectional communication with the label printer, so it detects the inserted label casette size to scale the font.

@Fabby Although after looking only at the title it might look opinion based but I don't think the question body says that it's opinion based. Like everyone should be careful enough while using sudo. And I think Sergiy's answer tells why and dessert's answer tells how to avoid that.
@dessert Just out of curiosity, since you are a gold badge holder for command line, what options you see while closing or reopening a question that is tagged with command-line
You could have reopened that single handedly. Or since you voted to reopen, I expected a gold badge appearing beside your name in "Post reopened by ..."
@dessert IMO reopening can be a tedious task since you have to be answerable to the community and it may happen that community don't agree. (Just my opinion)
UGH! I have not had the best of luck running with SNAP or flatpak. My libraries are stored on other drives and SNAP can't access it. However, I haven't tried flatpak on it yet.
So I ran this command on port 80 to check what is port 80 listening to. sudo lsof -i :80 and i got this. I dont understand what this means. Please tell me what this means as it seems like some program is running on our server and using tor exit nodes. How do i kill this malicious program.

@Fabby My gmail backup program is almost finished, now as always I need a name for the package. I was thinking of "GOB" -- Gmail Online Backup. But that sounds like an Acid Metal Band. The key feature is automating backup rotation form dailies to weeklies, montlies and then yearlies. So "GNR" for Gmail It & Rotate is another option. But that sounds like a girl band from the 90's or sounds like "Sit on it and rotate" which is also negative. Any ideas? I loved it when you came up with "Iconic"
BTW haha I was drinking and coding last night and ran the program set for 24 dailies, 20 weeklies, 18 monthlies and 99 yearlies and it trashed 600 backups. I went "OH NO TOO MANY!!!" So tonight I had to write an untrash function :P Lucky thing gmail has such a feature!
