List all files older than x days only in current directory
提问by Umesh Patil
I am new to unix and couldn't get appropriate outcome in other questions.
我是 unix 新手，无法在其他问题中获得适当的结果。
I want to list only files in current directory which are older than x days. I have below restriction
我只想列出当前目录中超过 x 天的文件。我有以下限制
- List only files in current folder which are older than 30 days
- Output shouldn't include directories and subdirectories
- This should list files similar as "ls" command does
- Output should look like
file1 file2 file3 ..
- 仅列出当前文件夹中超过 30 天的文件
- 输出不应包含目录和子目录
- 这应该列出类似于“ls”命令的文件
- 输出应该看起来像
file1 file2 file3 ..
I used find . -mtime +30. but this gives files and files in sub-directories as well. I would like to restrict doing search recursively and not to search inside directories.
我用过find . -mtime +30。但这也提供了子目录中的文件和文件。我想限制递归搜索而不是在目录内搜索。
Thanks a lot in advance !
非常感谢！

You can use find . -maxdepth 1to exclude subdirectories.
您可以使用find . -maxdepth 1排除子目录。

To add on @Richasantos's answer:
添加@Richasantos的回答：
This works perfectly fine
这工作得很好
$ find . -maxdepth 1 -type f -mtime +30
Prints:
印刷：
./file1
./file2
./file3
You can now pipe this to anything you want. Let's say you want to remove all those old files:
您现在可以将其通过管道传输到您想要的任何内容。假设您要删除所有这些旧文件：
$ find . -maxdepth 1 -type f -mtime +30 -print | xargs /bin/rm -f
From man find: ``
来自man find：``
If you are piping the output of find into another program and there is the faintest possibility that the files which you are searching for might contain a newline, then you should seriously consider using the
-print0option instead of
如果您将 find 的输出传送到另一个程序中，并且您正在搜索的文件可能包含换行符的可能性很小，那么您应该认真考虑使用该
-print0选项而不是
So using -print0
所以使用 -print0
$ find . -maxdepth 1 -type f -mtime +30 -print0
Prints (with null characters in between):
打印（中间有空字符）：
./file1./file2./file3
And is used like this to remove those old files:
并像这样用来删除那些旧文件：
$ find . -maxdepth 1 -type f -mtime +30 -print0 | xargs -0 /bin/rm -f

A slightly different spin on this: findis incredibly versatile, you can specify size and time as follows:
一个稍微不同的旋转：find非常通用，您可以指定大小和时间如下：
This finds you all the logs that are 4 months or older and bigger than 1 meg. If you remove the + sign, it finds files that are roughly that size.
这会为您找到 4 个月或更早且大于 1 兆的所有日志。如果删除 + 号，它会找到大致相同大小的文件。
find /var/log -type f -mtime +120 -size +1M
/var/log/anaconda/journal.log
/var/log/ambari-agent/ambari-alerts.log.23
/var/log/ambari-agent/ambari-alerts.log.22
/var/log/ambari-agent/ambari-alerts.log.24
/var/log/ambari-agent/ambari-alerts.log.25
/var/log/ambari-agent/ambari-alerts.log.21
/var/log/ambari-agent/ambari-alerts.log.20
/var/log/ambari-agent/ambari-alerts.log.19
What's even better, you can feed this into an ls:
更好的是，您可以将其输入到ls：
find /var/log -type f -mtime +120 -size +1M -print0 | xargs -0 ls -lh
-rw-r--r--. 1 root root 9.6M Oct 1 13:24 /var/log/ambari-agent/ambari-alerts.log.19
