10 years? Boy you are joung :)

I have encrypted files from w
20 years ago, and unencrypted files from 30 years ago.

And digitized stuff from analogic of 40 and 50 years ago.

Wow, who hurt you? Vim is fun, and just because you can make things work without it doesn't mean it has no practical benefit. It's nice to have an editor as powerful as an IDE that doesn't require a graphical environment.

Hundreds of shortcuts is emacs, by the way. A major perk of modal editing and the vi editing language is that you can compose relatively few operations to accomplish many tasks rather than memorizing lots of more complex and specific shortcuts.

yes no

Because it's so simple, a good default config can be a one-liner. For similar functionality to default sudo:

permit persist setenv {PATH=/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin} :wheel

What problems were you having where you couldn't get it to work?

$ echo {a,bb,ccc}{5,10,9999,888} | xargs -n3
a5 a10 a9999
a888 bb5 bb10
bb9999 bb888 ccc5
ccc10 ccc9999 ccc888
$ echo {a,bb,ccc}{5,10,9999,888} | xargs -n3 | column -t
a5      a10      a9999
a888    bb5      bb10
bb9999  bb888    ccc5
ccc10   ccc9999  ccc888

i just cat grep .bash_history lol

but this does sound more convenient xD

batcat

It's like cat but better. Great for when you just want to look at the contents of a file, without loading a whole text editor.

Oh also, tldr

My procedure for learning how to use a cli command goes tldr page -> --help if the tldr fails to help me -> THEN the full manpage

After spending years dealing with shady freeware and junk software on windows, I was floored by how easy and nonchalantly I was able to set up a simple security camera on my PC

For some cases I use “|| true”.

The idiom accepts that the preceding command might fail, and that’s OK.

For example, a script where mkdir creates a directory that might already exist.

ip eg:

# ip a
# ip a a 192.168.1.99/24 dev enp160

Oh and you can completely set up your IP stack, interfaces and routing etc with it. Throw in nft or iptables (old school these days - sigh!) for filtering and other network packet mangling shenanigans.

how is that better than

cat /dev/zero > /dev/null

or

while true; do :; done

losetup

it's useful for dealing with virtual disk images. like a real physical hard disk, but it's a file on the computer. you can mount it, format it, and write it to a real physical disk.

it's sometimes used with virtual machines, with iso images, or when preparing a bootable disk.

nmap *your_local_ip_address*

for example

nmap 192.168.1.43/24 will show you what devices are connected to the local network, and what ports are open there. really useful, for example, when you forgot the address of your printer or raspi yet again.

you can also use it to understand what ports on your computer are open from an attacker's perspective, or simply to figure out what services are running (ssh service).

socat - connect anything to anything

for example

socat - tcp-connect:remote-server:12345

socat tcp-listen:12345 -

socat tcp-listen:12345 tcp-connect:remote-server:12345

actually you can change your default text editor by putting export EDITOR=nano in your .bashrc file. Then files will open with nano instead.

Apart from that ... i still use nano as my main text editor in private, and i've been using that for over a decade now.

Who said it was better? It’s just my favourite.

Like my favourite shirt, it’s no better than the others, but it brings me a little joy :)

• on a serious note though, thank you for sharing your two examples - I didn’t know they existed.

I can't find the docs I followed, but this seems to be more or less the same process: ibm.com/support/pages/node/658…

There are version-specific AIX Toolbox installation scripts, so make sure you've got the right version (oslevel should help).

sudo !!

Will also run the previous command with sudo, fwiw.
