Linux Shell Cheat Sheet
1. 檢視Linux作業系統資訊:
uname -a
cat /proc/version
lsb_release -a
2. 設定ls顯示的資料夾的顏色(將下面這條目錄加在 .bashrc 檔案最後):
LS_COLORS=$LS_COLORS:'di=0;35:' ; export LS_COLORS
(All possible colors:
31 = red
32 = green
33 = orange
34 = blue
35 = purple
36 = cyan
37 = grey
90 = dark grey
91 = light red
92 = light green
93 = yellow
94 = light blue
95 = light purple
96 = turquoise
97 = white)
3. 在遠端伺服器X Server上顯示圖形介面:
ssh -x [email protected]
4. 強制轉換影象大小
convert -resize 1056x640! 000456.jpg 000456_640_1056.jpg
5. 檢視影象資訊
file 000456_640_1056.jpg
identify 000456_640_1056.jpg
6. 檢視物理CPU的個數
cat /proc/cpuinfo |grep "physical id"|sort |uniq|wc -l
7. 檢視邏輯CPU的個數
cat /proc/cpuinfo |grep "processor"|wc -l
8. 檢視一個物理CPU是幾核
cat /proc/cpuinfo |grep "cores"|uniq
9. 檢視當前目錄大小
du -h --max-depth=1 ./
