2. Install Cygwin under Windows
GUI安裝，大部分選擇預設值，以下項目要確認有被安裝

非連續資料，又需要保留資料順序的話，適合用
$ awk '!x[$0]++' example.txt > unique_file_example.txt
其作用方式是：告訴 awk 要輸出哪些行，其中變數 $0 是整個要處理的文字內容，中括號 [ ] 是要它用陣列的方式處理。
所以每一行的內容會++附加輸入到陣列 x 裡面，且必須是「!」沒有設定過的。

Basic Steps to Troubleshooting Bad Idle on a Corrado G60, for Beginners
First, do this basics to eliminate some variables:
DEGUNK THE Idle Stabilizer Valve (ISV) - Pull it off, spray it full of brake/parts/carb cleaner. Shake it around with the cleaner inside, empty it out, repeat until the cleaner comes out clear. Remember, do not unplug the ISV with the key in the accessory or on position. THis is bad for the ECU.
Check for vacuum leaks. There are a load of vacuum lines on the G60. The stock lines are rubber wrapped in a braided cloth and can dry-rot and crack. I replaced all of mine, from the dealer, for less than $40. Just ask for the diameters and lengths, and they should be able to cut them for you.
Here are the sizes, courtesy of the G60 Forum FAQ:
3.5 mm size line: 34" (brake booster line) + 39.5" (1 meter ECU line) + 6" (FPR) + 55"(charcoal mainifold) + 30" (air box to brake booster line) = 14.3 feet
9 mm size line: 40" (throttle body to charcoal)
5 mm size line: = 23" (brake booster to charcoal) + 28" (fuel tank breather line to charcoal) = 4 feet 3 inches.
That one-meter throttle-body to ECU line is important. There are two vacuum lines that go to the throttle body, and the ECU line connects to the nipple closest to the passenger side.
Second, Look at the electrical stuff.
Make sure there is no interruption in the spark: spark plugs/wires...make sure they are in good shape.
There's an electrical switch on the throttle body called the "idle switch" that should click on when the throttle is closed. Not surprisingly, the car will not idle right if this switch is fouled. It might not even start. It shares its connection to the harness with the wide-open throttle (WOT) switch, and the plug is on the back of the throttle body.
The fuel injector harness is in a crappy place, between the head and intake manifold, where there certainly is significant heat. The insulation gets very brittle over time and there is the potential for electrical shorts. Check it.
Look for corrosion at grounding points. Particularly the ground on the coolant flange on the (transmission) side of the cylinder head.
Third, determine under what conditions idle is poor.
>Is it bad when the car is cold but better when the car warms up?
>Or is it good when the car is cold and worsens when the car gets warmed up?
>Or is it just crappy all the time?
>Idle Is Bad When The Car Is Cold:
If you disconnect the blue coolant temp sensor while the engine is running and it idles better, you probably need a new blue coolant temp sensor.
If that doesn't do it, then check the O2 sensor, check your timing and reset your idle*
>Idle Is Bad When The Car Is Warm.
If you disconnect the o2 sensor before or while the engine is running, and the car idles better, you probably need a new o2 sensor.
If that doesn't do it, then check the blue CTS, check your timing and reset your idle.* If the idle is set too low, then the ISV will attempt to compensate for it once the car is out of cold-start mode, and the idle will be bonkers.
>Idle Just Sucks All The Time. Either the timing is way, way off, or you didn't set the idle right (too low).*
*Remember, the idle won't set correctly using the idle screw if you don't have the ISV unplugged.
And remember the method for setting the timing: The car must be warm, with the blue CTS unplugged, and the motor must be at ~2500 rpm. Set it for 6-8 degrees BTDC.
If idle is still bad, ask the experts in the G60 tech forum and read through the G60 tech forum FAQ if you haven't already and be sure to tell them you've done the basics.

打開 系統COM port或是SOL logs 會發現一些密密麻麻很難辨識的文字或符號
善用控制輸出速度的指令，就能像慢速回放一樣，重新檢視console跟SOL的Log囉

原廠後避震的長度：
備註：
1. 此表原始為某車行FB所提供的數據(該貼文已失效)，經查證發現有許多車款的數據是錯誤的長度。
2. 標註*代表，小弟沒查證過的部分
3. 許多車行/網拍，為了賣出改裝商品，標示其適用的車款不見得是正確的。
4. 避震器長度變更5mm以上所改變的車輛幾何，可能變好騎，也可能變難騎；改變太多的時候(大於原廠8-10mm以上)，車輛前後平衡變差，影響操控/煞車，亦可能導致輪胎不正常消耗。
5. 某些車款可能因長度加長，導致零件互相干涉，導致撞擊等。

Windows 11 - Switch WSL to 2 Error
$ wsl --set-default-version 2
Error: 0x800701bc WSL 2 requires an update to its kernel component. For information please visit https://aka.ms/wsl2kernel
1. Open "Control Panel"
2. Open "Program and Feature"
3. Click "Turn Windows features on or off"
4. Check the "Virtual Machine Platform" and "Windows Hypervisor Platform".
(一開始只安裝"Virtual Machine Platform"，但還是會報error，後來才補安裝"Windows Hypervisor Platform"，所以不確定是兩個都要還是"Windows Hypervisor Platform"足以)
5. OK then reboot OS
