![JOIN 返回的截断结果](https://linux22.com/image/55126/JOIN%20%E8%BF%94%E5%9B%9E%E7%9A%84%E6%88%AA%E6%96%AD%E7%BB%93%E6%9E%9C.png)
我在linux下使用join命令,但是不同机器的结果不同。我有两个简单的文件:
cat 1.txt
a aaa,0.2
b bbb,0.3
c ccc,0.5
cat 2.txt
a aaa,0.2
b bbb,0.3
c ccc,0.6
我正在运行以下命令
join -a 1 -1 1 -2 1 -t "," -o 1.1' '1.2' '2.2 <(cat 1.txt| sort -t ",") <(cat 2.txt| sort -t ",")
机器 1 上的结果:
,0.2a,0.2
,0.3b,0.3
,0.6c,0.5

机器2上的结果:
a aaa,0.2,0.2
b bbb,0.3,0.3
c ccc,0.5,0.6
join --version

显然,第一台机器上的结果是错误的。它已被截断。我尝试使用不同的区域设置但没有成功。

使用 修复您的文件dos2unix

sed -i 's/\r$//' {1,2}.txt
