如何合并unix中的两个文件

Question

我想在Unix中合并两个文件。我怎样才能做到这一点？

例如文件1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 

文件2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 

我已经使用这个命令paste -d ':' file1 file2 >merged_file，但是这是我得到：

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

使用join代替：

% 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
