1. Introduction Parameters
pathname: find命令所查找的目录路径。例如用.来表示当前目录，用/来表示系统根目录。
-print： find命令将匹配的文件输出到标准输出。
-exec： find命令对匹配的文件执行该参数所给出的shell命令。相应命令的形式为'command' { } \;，注意{ }和\；之间的空格。
-ok： 和-exec的作用相同，只不过以一种更为安全的模式来执行该参数所给出的shell命令，在执行每一个命令之前，都会给出提示，让用户来确定是否执行。
#-print 将查找到的文件输出到标准输出
#-exec command {} \; —–将查到的文件执行command操作,{} 和 \;之间有空格
#-ok 和-exec相同，只不过在操作前要询用户

Find / -size + 10M | -l -H xargs LS
# identify the system files larger than 10M through the conduit back to the program processing xargs
Find -size -1k.
# identify the current directory, the file is less than 1k, Note that the directory can be considered
the find. the -type f -size -2k
# to find out the current directory, the file is less than 2K, but file
the find. -name " " the -type f -size 0c
# find empty file in the current directory, 0c represents 0 bytes
find -type -size -10K -exec F {cp} / root / 233 \;.
# to find out the current directory files smaller than 10K, copied to / root / 233 cp directory by running exec command format attention exec it is wonderful to be with \; the end of
the find -name. " .txt" | xargs RM # to find out the current directory, txt file types, delete
find / home -links +2 # check hard links to directories or files larger than 2
find / home -perm 0700 # 700 check permissions for the file or directory
find / -nouser # Find belonging to void the user in the system file
find / -user fred # find FRED belong to the user's file system,
find / -empty # find empty in the system file or folder
find / -group cat # find files in the system belongs to groupcat
find / -type f -amin -10 # access system to find the last 10 minutes of the file
find / -type f -atime -2 # Find access the last 48 hours in a file system
find / -type f -empty # Find system empty file or folder
find / -type f -mmin -5 # Find the last five minutes of the modified file in the system
find / -type f -mtime -1 # search the last 24 hours in the modified system file.
find / home -type f -mtime -2 # checked altered in the last two days at the file / home
Find / home -type -1 # F -atime check under / home is accessed through within 1 day file
find / home -type f -mmin +60 # check under / home 60 minutes before the altered file
find / home -type f -amin +30 # check under / home recently accessed over 30 minutes before file
find. -type f -atime -7 -print # list all files in the current directory being visited in the last 7 days
find. -type f -atime 7 -print # list all files in the current directory happens to be visited before the seventh day
find. -type f -atime +7 -print # List all files in the current directory access for more than seven days
. find -type f -newer file.txt -print # to find out the current directory file.txt modification longer than all files, use -newer, you can refer to
(-atime is based on access time; -mtime is modified according to time; -ctime is a change in the time unit of the three parameters are the days).
(the access time is -amin; -mmin is a modification time;. -cmin is a time variation of these three parameters in minutes)
