如何在unix中合并两个文件

Question

我想在Unix中合并两个文件。我怎么能这样做？

例如file1包含：

host1:90:/users:user1 
host2:90:/users:user1 
host3:90:/users:user1 
host4:90:/users:user1
host5:90:/users:user1 
host6:90:/users:user1 
host7:90:/users:user1

file2包含：

host1:owner_name
host2:owner_name
host3:owner_name
host4:owner_name
host5:owner_name
host6:owner_name
host7:owner_name

输出结果：

host1:90:/users:user1:owner_name
host2:90:/users:user1:owner_name
host3:90:/users:user1:owner_name
host4:90:/users:user1:owner_name
host5:90:/users:user1:owner_name
host6:90:/users:user1:owner_name
host7:90:/users:user1:owner_name

我使用了这个命令paste -d ':' file1 file2 >merged_file，但这就是我得到的：

host1:90:/users:user1:host1:owner_name
host2:90:/users:user1:host2:owner_name
host3:90:/users:user1:host3:owner_name
host4:90:/users:user1:host4:owner_name
host5:90:/users:user1:host5:owner_name
host6:90:/users:user1:host6:owner_name
host7:90:/users:user1:host7:owner_name

改为使用join：

% join -t':' file1 file2
host1:90:/users:user1:owner_name
host2:90:/users:user1:owner_name
host3:90:/users:user1:owner_name
host4:90:/users:user1:owner_name
host5:90:/users:user1:owner_name
host6:90:/users:user1:owner_name
host7:90:/users:user1:owner_name
