find

问题 I'd like to find human-readable files on my linux machine without a file extension constraint. Those files should be of human sensing files like text, configuration, html, source-code etc. files. Could you suggest a way to filter and locate. 回答1: find and file are your friends here: find /dir/to/search -type f -exec sh -c 'file -b {} | grep text &>/dev/null' \; -print this will find any files ( NOTE: it will not find symlinks directories sockets etc only regular files ) in /dir/to/search and

问题 I am new to linux. I have a directory in linux with approx 250,000 files I need to find count of number of files matching a pattern. I tried using following command : ls -1 20061101-20131101_kh5x7tte9n_2010_* | wc -l I got the following error message: -bash: /bin/ls: Argument list too long 0 Please help. Thanks in advance 回答1: It might be better to use find for this: find . -name "pattern_*" -printf '.' | wc -l In your specific case: find . -maxdepth 1 -name "20061101-20131101_kh5x7tte9n_2010

问题 After looking on MSDN, it's still unclear to me how I should form a proper predicate to use the Find() method in List using a member variable of T (where T is a class) For example: public class Car { public string Make; public string Model; public int Year; } { // somewhere in my code List<Car> carList = new List<Car>(); // ... code to add Cars ... Car myCar = new Car(); // Find the first of each car made between 1980 and 2000 for (int x = 1980; x < 2000; x++) { myCar = carList.Find(byYear(x)

问题 This question already has answers here : Delete all files older than 30 days, based on file name as date (2 answers) Closed last month . I have some logs files with somefiles.log.YYYY-mm-dd and I want to delete those files that are older than N days base on the timestamp in its filename. 回答1: use cut command to retrieve YYYY-MM-dd part of filename. and use date command as following to convert it to time_t type. date -d "YYYY-MM-dd" +%s then you can compare time_t to determine which file

问题 The following works from the terminal no problem find testDir -type f -exec md5sum {} \; Where testDir is a directory that contains some files (for example file1, file2 and file3). However, I get an error using the following in Java Runtime rt = Runtime.getRuntime(); Process pr = rt.exec("find testDir -type f -exec md5sum {} \\;"); The error is find: missing argument to `-exec' I believe I am escaping the characters correctly. I have tried several different formats and I cannot get this to

问题 I use a command to recursively find files containing a certain string1 : find . -type f -exec grep -H string1 {} \; I need to find files containing multiple strings, so the command should return those containing all strings. Something like this: find . -type f -exec grep -H string1 AND string2 {} \; I couldn't find a way. The strings can be anywhere in the files. Even a solution for only two strings would be nice. 回答1: you can also try this; find . -type f -exec grep -l 'string1' {} \; |

问题 I have MongoDB collection of documents containing several fields. One of the columns/fields should be numeric only, but some of these fields contain non-numerical (corrupt) data as string values. I should find the highest numerical value of this column, excluding the corrupt, non-numerical data. I am aware of the question Getting the highest value of a column in MongoDB, but AFAIK, this extended case was not covered. The example below depicts the issue. For the highest value, the document
