Print directory Structure
[[email protected] ~]# find. -type D-print
Print non-catalog files

Because grep cannot recursively search subdirectories, it can be used in conjunction with find. Find a string in the. h file in all/usr/include subdirectories Af_inef6

[[email protected] ~]# find. -size 100c-print
#看是否存在cnscn用户
[[email protected] ~]# find/etc-name "passwd*"-exec grep "Cnscn" {} \;

-rw-r--r--1 root root 34928 2003-02-25./conf/httpd.conf
-rw-r--r--1 root root 12959 2003-02-25./conf/magic
-rw-r--r--1 root root 2003-02-25./conf.d/readme
Check all the normal files in the current directory and use the LS-L command in the-e x E C option to list them
Second, the use of the Linux find command
1. Basic usage:
Find/-name file name
Find ver1.d ver2.d-name ' *.c '-print finding ver1.d,ver2.d *.c files and printing
Find. -type D-print from the current directory, finds only the directory, and when found, prints the path name. Can be used to print the directory structure.
2. No Error Lookup:
Find/-name Access_log 2 >/dev/null
3. Search by Size:
Find/-size 1500c (look for a 1,500-byte file, c for bytes)
Find/-size +1500c (finds files larger than 1,500 bytes, + represents greater than)
Find/-size +1500c (finds files less than 1,500 bytes in size-Indicates less than)
4. By Time:
Find/-amin n last N minutes
Find/-atime n last n days
Find/-cmin n last N minutes change state
Find/-ctime N last n days change state
5. Other:
Find/-empty blank file, blank folder, folder without subdirectories
Find/-false files that are always wrong in the lookup system
Find/-fstype Type Locate the file that exists in the specified file system, such as type ext2
Find/-gid n set of files with ID n
Find/-group gname group file named Gname
Find/-depth N first search for file contents in a certain level of specified directory
Find/-maxdepth levels in a hierarchical directory in descending order
6. Logic
-and conditions and-or conditions or
7. Finding strings
Find. -name ' *.html '-exec grep ' mailto: ' {}
