I want to easily check the listen port of a process and conveniently output the used port and service
This article is a continuation of the above.

Hello, it's me, the incompetent one.
I really need some simple system information.
And since I ended up with a command that's too unreadable, I'll try to make it automatically determine things later based on the return value of which...

Connecting pipes like this makes it completely unreadable, so I'll break them down.
If I just use a one-liner like this, many people will get angry, so it's not good.
But I wonder if the CLI getting cluttered is the magic of history____

When it's lengthy,

set -o vi

you can be happy by performing operations in vi mode. It's also effective before setting keymaps if you don't have arrow keys.

FreeBSD

echo -e "`sysctl -n hw.model`\n`printf "%.2f GB\n" $(echo "scale=2; $(sysctl -n hw.realmem) / 1024 / 1024 / 1024" | bc)`\n\n`df -h`\n" &&  lsof -i -P -n | grep "LISTEN" |  awk '{print $1 "," $3 "," $9 "/" $8}' | sort | uniq | column -t -s ","

sysctl -n hw.model CPU information
printf “%.2f GB\n” $(echo “scale=2; $(sysctl -n hw.realmem) / 1024 / 1024 / 1024” | bc) Memory df -h Disk lsof * Listen port

GNU/Linux

echo -e "`grep "model name" /proc/cpuinfo | head -1`\n`awk '/MemTotal/ { printf "%.2f GB\n", $2 / 1024 / 1024 }' /proc/meminfo`\n\n`df -h`\n" &&  lsof -i -P -n | grep "LISTEN" |  awk '{print $1 "," $3 "," $9 "/" $8}' | sort | uniq | column -t -s ","

grep “model name” /proc/cpuinfo | head -1 CPU information awk ‘/MemTotal/ { printf “%.2f GB\n”, $2 / 1024 / 1024 }’ /proc/meminfo Memory df -h Disk lsof * Listen port

After that, I'm passing to the next execution with &&, but I need to format everything to be easily readable with the column command.
Although I'm doing it as a one-liner for testing, I'll make sure each part can be executed individually within the code later.

I was curious why df's Japanese output stopped at ファイルシス (Filesystem), so I looked at df.c in coreutils when $LANG is ja_JP.UTF-8.

It's not here...
It seems to be po/ja.po, but I wonder where the Japanese version is currently managed.

It seems to be translated above, but df doesn't exist.
Hmm.

It's quite annoying.
