ls -l –time-style命令查看文件是星期几创建的几种方法

查看文件是星期几创建的几种方法总结了以下三种方法：
1.使用ls命令结合grep的方法：
ls -l –time-style ‘+%A’ | grep -E “Tuesday|Wednesday”
2.使用AWK的方法1：
[Oracle@bys3 ~]$ ls -l –time-style ‘+%A’|awk ‘$6==”Friday”||$6==”Tuesday” {print $0}’
-rw-r–r– 1 oracle oinstall 253 Friday archback.sh
-rw-r–r– 1 oracle oinstall 199 Friday bbedfile.txt
-rw-r—– 1 oracle oinstall 1958583 Friday bys3_ora_13020.trc
-rw-r–r– 1 oracle oinstall 350 Tuesday delarch.sh
drwxr-xr-x 3 oracle oinstall 4096 Tuesday oradiag_oracle
[oracle@bys3 ~]$

3.使用AWK的方法2： –有点复杂了
declare -a array
array=(`ls -l –time-style ‘+%A’ | awk ‘{print $6}’`)
echo ${array[0]}
length=${#array[@]}
echo $length
for ((i=0;i<$length;i++))
do
case ${array[$i]} in Tuesday|Wednesday)
ls -l –time-style ‘+%A’ | grep -E ${array[$i]}
esac
done
~
4.ls -l –time-style命令的几种用法示例： –可以把常用的在环境变量写成alias ls=’ ‘
[oracle@bys3 ~]$ ls -l –time-style=”+%Y-%m-%d $newline%m-%d %H:%M” –显示了详细的年月日时分
