今天给大家分享一些云计算学习路线课程大纲资料，这篇文章是关于参数传递 Xargs的一些学习笔记资料，希望能给大家一些帮助：
====================================================================================
awk sed grep sort uniq less more xargs
xargs: ls cp rm
案例1
[root@localhost ~]# touch /home/file{1..5}
[root@localhost ~]# vim files.txt
/home/file1
/home/file2
/home/file3
/home/file4
/home/file5
[root@localhost ~]# cat files.txt |ls -l
[root@localhost ~]# cat files.txt |rm -rvf
cont.
[root@localhost ~]# cat files.txt |xargs ls -l
-rw-r--r--. 1 root root 0 Mar 11 10:35 /home/file1
-rw-r--r--. 1 root root 0 Mar 11 10:35 /home/file2
-rw-r--r--. 1 root root 0 Mar 11 10:35 /home/file4
-rw-r--r--. 1 root root 0 Mar 11 10:35 /home/file5
[root@localhost ~]# cat files.txt |xargs rm -rvf
removed ‘/home/file1’
removed ‘/home/file2’
removed ‘/home/file4’
removed ‘/home/file5’
案例2
[root@localhost ~]# touch /home/file{1..5}
[root@localhost ~]# cat files.txt |xargs -I {} ls -l {}
-rw-r--r--. 1 root root 0 Mar 11 10:40 /home/file1
-rw-r--r--. 1 root root 0 Mar 11 10:40 /home/file2
-rw-r--r--. 1 root root 0 Mar 11 10:40 /home/file4
-rw-r--r--. 1 root root 0 Mar 11 10:40 /home/file5
[root@localhost ~]# cat files.txt |xargs -I {} cp -rvf {} /tmp
‘/home/file1’ -> ‘/tmp/file1’
‘/home/file2’ -> ‘/tmp/file2’
‘/home/file4’ -> ‘/tmp/file4’
‘/home/file5’ -> ‘/tmp/file5’
[root@localhost ~]# cat files.txt |xargs -I YANG cp -rvf YANG /var/tmp
‘/home/file1’ -> ‘/var/tmp/file1’
‘/home/file2’ -> ‘/var/tmp/file2’
‘/home/file4’ -> ‘/var/tmp/file4’
‘/home/file5’ -> ‘/var/tmp/file5’
案例3
[root@localhost ~]# find /etc -iname "*ifcfg*" |xargs -I {} cp -rf {} /tmp
