list files in a directory based on timestamp
提问by iamauser
In bash, is there a command line to list all the files in a directory based on a timestamp. e.g.,
在 bash 中,是否有一个命令行可以根据时间戳列出目录中的所有文件。例如,
\ls -ltr dir/file*
-rw-r--r-- 1 anon root 338 Aug 28 12:30 g1.log
-rw-r--r-- 1 anon root 2.9K Aug 28 12:32 g2.log
-rw-r--r-- 1 anon root 2.9K Aug 28 12:41 g3.log
-rw-r--r-- 1 anon root 2.9K Aug 28 13:03 g4.log
-rw-r--r-- 1 anon root 2.9K Aug 28 13:05 g5.log
I want to list all the files that have timestamp before Aug 28 13:00
.
我想列出所有具有时间戳之前的文件Aug 28 13:00
。

You can use find command if you know the number of days
如果您知道天数,则可以使用 find 命令
find ./ -mtime -60
+60 means you are looking for a file modified 60 days ago.
+60 表示您正在查找 60 天前修改的文件。
60 means less than 60 days.
60 表示少于 60 天。
60 If you skip + or - it means exactly 60 days.
60 如果您跳过 + 或 -,则表示正好是 60 天。

The time displayed by ls -la
is the last modification date. To list all the files in a directory which have been last modified before 2013/08/28 13:00:00
, use the following find
command:
显示的时间ls -la
为最后修改日期。要列出目录中最后修改过的所有文件2013/08/28 13:00:00
,请使用以下find
命令:
find -maxdepth 0 -type f -newermt '2013-08-28 13:00:00'

Try this command:
试试这个命令:
read T < <(exec date -d 'Aug 28 13:00' '+%s') && find /dir -type f | while IFS= read -r FILE; do read S < <(exec stat -c '%Y' "$FILE") && [[ S -lt T ]] && echo "$FILE"; done
Also, if your find
comand support -newerXY
you could have this:
另外,如果你的find
命令支持-newerXY
你可以有这个:
find /dir -type f -not -newermt 'Aug 28 13:00'

Touch a file with the time stamp and find all older files.
触摸带有时间戳的文件并查找所有较旧的文件。
touch -d 'Aug 28 13:00' /tmp/timestamp
find . ! -newer /tmp/timestamp

I love pure bash solutions (well, not considering date
and stat
):
我喜欢纯 bash 解决方案(好吧,不考虑date
和stat
):
dateStr='Aug 28 13:00'
timestamp=$(date -d "$dateStr" +%s)
for curFile in *; do
curFileMtime=$(stat -c %Y "$curFile")
if (( curFileMtime < timestamp )); then
echo "$curFile"
fi
done
The results are not going to be sorted, because you didn't mention that you want them in sorted order.
结果不会被排序,因为你没有提到你想要它们按排序顺序。

First, find out how old a file must be to have a timestamp earlier than (e.g.) Aug 28 at 13:00.
首先,找出文件的时间戳必须早于(例如)8 月 28 日 13:00。
now=$(date +%s)
then=$(date +%s --date "2013-08-28 13:00")
minimum_age_in_minutes=$(( (now-then)/60 ))
Then, use find
to find all files that are at least minimum_age_in_minutes
old.
然后,用于find
查找至少minimum_age_in_minutes
旧的所有文件。
find "$dir" -mmin "+$minimum_age_in_minutes"
