linux 系统中查找文件的命令find,虽然linux命令入手比较困难,但linux命令功能确实很强大, find"命令查找文件只要灵活应用,丝毫不必在WINDOWS中查找能力差"。 #在根目录下查找“mysql” find / -name 'mysql' #查找home目录下大于10000000byte的文件 find ~ -size +10000000c #查找当前文件下名为“e-book”的文件夹 find . -name "e-book" -type d #查找符合条件的文件厚将其删除 find ~/temp/test -name "*.py" -type f | xargs rm -f #按条件查找到文件后,执行 -exec 命令 find ./temp/test/gbk/ -type f -exec file "{}" \; #查找符合权限的文件 find . -perm -664 #将当前目录下最近30天访问过的文件移动到上级back目录 find . -type f -atime -30 -exec mv {} ../back \; #删除当前目录中所有.svn目录 find . -name .svn -type d -exec rm -rf {} \; #删除当前目录所有以“~” 结尾的临时文件 find . -name "*~" -exec rm {} \;

Android Bluetooth StartDiscovery() always returns false

落爺英雄遲暮 提交于 2021-02-18 12:16:04
问题 I am trying to discover bluetooth devices nearby, but startDiscovery() always returns false, as if it is not working. Therefore it is not able to find devices. I saw that i have to include Coarse_Location permission apart from Bluetooth and Bluetooth_Admin, but anyway, it doesn´t work. Here is the code I am trying right now, where there are mainly traces to see how it works: public class BluetoothActivity extends AppCompatActivity { RecyclerView recyclerView; ArrayList<BluetoothDevice>

Selenium - Find all elements of a web page

问题 I am planning a tool in Java which would have a drop down containing all the elements of a web page. Is there any way I can read those into a data structure? 回答1: Yes, there is a way. Here is some pseudo-code: List<WebElement> el = driver.findElements(By.cssSelector("*")); for ( WebElement e : el ) { add(e.tagName()); } 回答2: non-pseudo C# version of above: (although I'm just displaying the results in a console IReadOnlyCollection el = driver.FindElements(By.CssSelector("*")); foreach

bash: -exec in find command and &

问题 I want to run: ./my_script.py a_file & ... on all files in the current folder that end with .my_format , so I do: find . -type f -name "*.my_format" -exec ./my_script {} & \; but it doesn't work. How should I include & in the -exec parameter? 回答1: Try this: $ find . -type f -name "*.my_format" -exec sh -c './my_script {} &' \; The mostly likely reason your attempt didn't work is because find executes the command using one of the exec(3) family of standard c library calls which don't

Python Pandas dataframe find missing values

余生颓废 提交于 2021-02-16 20:18:15
问题 I'm trying to find missing values and then drop off missing values. Tried looking for the data online but can't seem to find the answer. Extracted Dataframe: In the df, for 1981 and 1982, it should be '-', i.e. missing values. I would like to find the missing values then drop off the missing values. Exported Dataframe using isnull: I used df.isnull() but in 1981 and 1982, it's detected as 'False' which means there's data. But it should be '-', therefore considered as missing values. I had

python find last in string

问题 I'm looking for a simple method of identifying the last position of a string inside another string ... for instance. If I had: file = C:\Users\User\Desktop\go.py and I wanted to crop this so that file = go.py Normally I would have to run C:\Users\User\Desktop\go.py through a loop + find statement, and Evey time it encountered a \ it would ask ... is the the last \ in the string? ... Once I found the last \ I would then file = file[last\:len(file)] I'm curious to know if there is a faster
