shell - 从目录中删除特定文件

Question

我们在某个文件夹中有一些文件以这种名称格式 BKK-20170428082153.war

我们需要删除比当前日期早一周的所有文件。

我试过这个命令find . -name "*.war" -type f -delete ，但它不检查我想要的日期规则。

谁能帮我吗。

Answer 1

给出的答案非常好，应该为您服务。

我仍然希望根据文件名而不是基于时间戳进行删除，试试这个。

alias delete-weeks-war='for i in {1..7};do rm BKK-`date -v-${i}d +%Y%m%d`*.war; done'

用法

$ cd wars-directory
$ delete-weeks-war # simple as ... that

解释

# traverses the last seven days starting from yesterday
# set to 0..6 to start from today
for i in {1..7} 
do
    # calculates timestamp, only the part of year, month, day
    t=`date -v-${i}d +%Y%m%d` 
    # builds the expected file name
    # to cover all combinations for hour, time and seconds there is the asterisk
    file="BKK-${t}*.war"
    # removes the designated files
    rm $file
    # if no files found you will get an error like
    # rm: BKK-20170428*.war: No such file or directory
    # to get rid of this error message use the following rm instead of the previous
    # rm $file 2>/dev/null
done

我相信它完全符合您的需求。
