MacOS: M系列 CPU brewhome 安裝位置問題

2023-08-102023-08-10 老王

Homebrew 路徑變更為 /opt/homebrew/bin , 造成自建程式引用問題(intel 時代的目錄為 /usr/local/bin)
使用以下放法解決:

如果你沒有 /usr/local/bin 就跳過這個部份

/usr/local/bin/* /opt/homebrew/bin/
rm -rf /usr/local/bin

1 2	/usr/local/bin/* /opt/homebrew/bin/ rm -rf /usr/local/bin

然後

ln -s /opt/homebrew/bin /usr/local/bin

1	ln -s /opt/homebrew/bin /usr/local/bin

就能得到一致的環境

Linux: awk 內置文字處理 split/substr/length

2021-09-182021-09-18 老王

基本說明：
split(string, array[, field separator]) : 字串,變數名稱,分割符號(預設當前FS)
ex: 取出第二個元素,再使用":" 分割字串存成陣一列 ar ,再print 出 ar 第二個元素

echo "123:456 789:abc" | awk '{ split($2,ar,":"); print ar[2]}'
abc

1 2	echo "123:456 789:abc" \| awk '{ split($2,ar,":"); print ar[2]}' abc

substr(string,p[,n]): 字串,從p開始,長度為n
ex: 使用 substr 取出第二個元素, 從第3個字元開始，取1個字元

echo "1234 5678 9abc" | awk '{print substr($2,3)}'
78
echo "1234 5678 9abc" | awk '{print substr($2,3,1)}'
7

echo "1234 5678 9abc" | awk '{print substr($2,3)}'

echo "1234 5678 9abc" | awk '{print substr($2,3,1)}'

length([string]): 返回字串長度，預設為$0
ex:

echo "1234 5678 9abc" | awk '{print length()}'
14
echo "1234 5678 9abc" | awk '{print length($1)}'
4

echo "1234 5678 9abc" | awk '{print length()}'

echo "1234 5678 9abc" | awk '{print length($1)}'

綜合應用
處理nginx log
1.每10秒的連線計數

cat nginx.log | awk '{ print substr($4,14,7)}'  | sort | uniq -c

1	cat nginx.log \| awk '{ print substr($4,14,7)}' \| sort \| uniq -c

2.統計IP 使用 class C

cat nginx.log | awk '{ split($1,ipar,".") ; print ipar[1]"."ipar[2]"."ipar[3]".0"}' | sort | uniq -c

1	cat nginx.log \| awk '{ split($1,ipar,".") ; print ipar[1]"."ipar[2]"."ipar[3]".0"}' \| sort \| uniq -c
