, , type sudo and enter is nearly as quick and much more explicit for me.

Although these tools are great, I'm afraid these are of limited use, as these aren't preinstalled but must be explicitly installed. For personal use these are great. But if you write a shell script to be executed on different machines where you can't install anything, these tools won't be available to you. And if you don't have that requirement, i.e. you can install everything, just install appropriate Perl/Python/Ru…
Why assume python? It's huge compared to bash or perl. Lots of minimal configuration operational systems won't have python. More likely than go/ruby/node though.
This bit us in our ass with centos 6.8 , when another package required python 2.7... If you install 2.7 directly, your system fails with a thousand cuts. A chroot is needed for that, unfortunately.
Just look at anything in the "moreutils" package. Just great stuff. Excerpt: - ifdata: do not parse the output of ifconfig/ip anymore. Just use this tool. - sponge: when you need to overwrite an input file at the end of pipe. sponge will wait for the pipe to end before overwriting, preventing any data loss - vidir: edit a given dir with your EDITOR. Awesome for mass renames/deletes. - ts: add timestamps to a command…
One of my favorite moreutils tools is combine[1]. It allows you to compare the contents of text files with boolean operations. For example, want to know what lines are in file1 but not file2? Use: combine file1 not file2 1. http://manpages.ubuntu.com/manpages/zesty/en/man1/combine.1....

Why crazy?
A large proportion (if not the majority) of the world starts their calanders on Monday. While the ordering is arbitrary, I always thought of the weekend as a single block of days so it's odd to say that the week ends in the middle of the weekend (rather than at the end of the week end ).

When you're using Python/Perl/Ruby you'll often have to use pip/cpan/rvm for dependencies, and you're back to square one.

Is that really a problem anymore? Not being able to install things was common in multi-user thin-client type systems, but these days with containerisation and VMs, if you're allowed to execute a script, you're probably allowed to install new packages No?
Sadly, no. It is often possible to install things locally, i.e. not using apt. The idea that everyone has sudo privs is unrealistic. A version of apt that added a per user subset would be very useful.
"cal -3" is quite useful, I use it all the time. To show the week-of-year use "ncal -w". Add "-S" if you want ncal to start weeks on Sunday (crazy!).
Use `cal -m` if you want a week to start on a Monday. AFAIK Sunday is the (US centric) default.

You can use comm from coreutils for that too: `comm -1 file1 file2`

Bringing this on a small tangent, but I've never been comfortable with 'sudo !!' and I can't really articulate why aside from wanting to be as explicit as possible. , , type sudo and enter is nearly as quick and much more explicit for me.
