sed 使用单引号引用外部变量

cat *.result.txt | awk ‘{print $2}’
cat *.result.txt | awk ‘{print $2}’ | sort | uniq
cat *.result.txt | awk ‘{print $2}’ | sort | uniq -c
筛选共同的行列：
只选表1的值
cat *.result.txt | awk '{print KaTeX parse error: Expected 'EOF', got '}' at position 2: 2}̲' | sort | uni…line ‘$2==V1{print $1}’ `; echo l i n e , line, line,num1_1; done
选表1和2的值
cat *.result.txt | awk '{print KaTeX parse error: Expected 'EOF', got '}' at position 2: 2}̲' | sort | uni…line ‘$2V1{print KaTeX parse error: Expected 'EOF', got '}' at position 2: 1}̲' `;num1_2=`cat…line '$2V1{print $1}’ `;echo l i n e , line, line,num1_1,$num1_2; done
值的计算
cat *.result.txt | awk '{print KaTeX parse error: Expected 'EOF', got '}' at position 2: 2}̲' | sort | uni…line '$2V1{print KaTeX parse error: Expected 'EOF', got '}' at position 2: 1}̲' `;num1_2=`cat…line '$2V1{print KaTeX parse error: Expected 'EOF', got '}' at position 2: 1}̲' `;xiaoshu=`ec…num1_1/$num1_2"| bc` ;echo -e KaTeX parse error: Undefined control sequence: \t at position 6: line"\̲t̲"xiaoshu; done
cat *.result.txt | awk '{print KaTeX parse error: Expected 'EOF', got '}' at position 2: 2}̲' | sort | uni…line ‘$2V1{print KaTeX parse error: Expected 'EOF', got '}' at position 2: 1}̲' `;num1_2=`cat…line '$2V1{print $1}’ `;echo l i n e ; e c h o " s c a l e = 4 ; line;echo "scale=4; line;echo"scale=4;num1_1/$num1_2"| bc ; done
另外一种方法：
cat nzero | while read line ; do num=echo $line | awk '{print $1}'; name=echo $line | awk -F"_" '{print $2"_"$3}';echo -e KaTeX parse error: Undefined control sequence: \t at position 5: num"\̲t̲"name; done
在sed命令中使用外部变量有两种方式：
（1）sed命令使用双引号而不是单引号
例：var=cat
echo "It is a dog" | sed "s/dog/$var/g"
（2）sed命令依然使用单引号，但将外部变量用单引号括起来
例：var=cat
echo "It is a dog" | sed 's/dog/'$var'/g'
