> 寻找当前母目录下包含”xml”这三个字符的文件。如果找到的胡话，就在当前的屏幕上打印出来。

### 获取/目录下的内容 ###

[root@VM_156_149_centos ~]# ls -l /

    lrwxrwxrwx.  1 root root     8 Apr 21  2016 sbin -> usr/sbin
    drwxr-xr-x   2 root root  4096 Aug 19 17:40 shell
    drwxr-xr-x.  2 root root  4096 Aug 12  2015 srv

    drwxr-xr-x. 19 root root  4096 Aug 19 13:21 var

### 使用awk获取到，每一行里面第9列的内容 ###

[root@VM_156_149_centos ~]# ls -l / | awk '{ printf $9 " " } '
    bin boot data dev etc home lib lib64 lost+found media mnt opt proc root run sbin shell srv sys tmp usr var

### 在获取的第9列中，筛选出符合条件的内容，例如”包含b字符” ###

[root@VM_156_149_centos ~]# ls -l /  | grep "b" --color | awk '{ printf $9 " " } '
    bin boot lib lib64 sbin

### Shell Script 1 ###

#!/bin/sh 
    #获取符合条件的行
    FILES=` ls -l / |  awk '{print $9}'  `
    #输出获取的行的内容
    echo $FILES
    #进行条件的过滤
    for filename in $FILES
    do
       echo $filename | grep "b" --color
    done

输出结果

[root@VM_156_149_centos shell]# sh 2.sh
    bin boot data dev etc home lib lib64 lost+found media mnt opt proc root run sbin shell srv sys tmp usr var
    bin
    boot
    lib
    lib64
    sbin

### Shell Script 2 ###

#!/bin/sh 
    for filename in `ls /`
    do
        if [[ $filename = *b*  ]]  ; then
          echo $filename
        fi
    done

输出结果

[root@VM_156_149_centos shell]# sh 8.sh
    bin
    boot
    lib
    lib64
    sbin
