#1

awk '{ print $2 }' text.txt > outputfile.txt

> => This will redirect STDOUT to a file. If file not exists, it will create it. If file exists it will clear out (in effect) the content and will write new data to it

这将把STDOUT重定向到一个文件。如果文件不存在，它将创建它。如果文件存在，它将清除(实际上)内容并向其写入新数据

>> => This means same as above but if file exists, this will append new data to it.

>> =>这和上面的意思一样，但是如果文件存在，这将向它添加新数据。

Eg:

例如:

$ cat /etc/passwd | awk -F: '{ print $1 }' | tail -10 > output.txt
$ cat output.txt 
_warmd
_dovenull
_netstatistics
_avbdeviced
_krb_krbtgt
_krb_kadmin
_krb_changepw
_krb_kerberos
_krb_anonymous
_assetcache

Alternatively you can use the command tee for redirection. The command tee will redirect STDOUT to a specified file as well as the terminal screen

您也可以使用命令tee进行重定向。命令tee将STDOUT重定向到指定的文件以及终端屏幕
