查找指定目录下包含"xml"的文件

Posted 2022-12-03 Bwz_Learning

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 /

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
