finds the file name or directory name under the absolute path
find /etc - name XX //absolute file name or directory name find /etc -iname XX //case-insensitive file name or directory name search
Wildcard lookup
find /etc/ -name '*XX*' //* wildcard any character find /etc/ -name 'XX?' //? wildcard a character find /etc/ -name '[XX].sh' //[any character in the wildcard] find /etc/ -name XX -user //Find files by belonging user and group find /etc/ -name XX -group //Find files by their owning users and groups find /tmp -uid uid //find files with uid 500 find /tmp -gid 500 //find files with gid 500 find /tmp /etc -name XX //Multiple paths are searched together find /tmp -name 'XX.sh' -a -user root //Use -a to connect two && conditions find /tmp -name 'XX.sh' -o -user root //Use -o to connect two || conditions find /tmp -not -user root //Use -not to negate the condition
Find files by timestamp dimension
stat /etc/tmp #-atime //Last visit time #-mtime //The last content modification time #-ctime //The last attribute modification time #-amin //The unit is days #-mmin //The unit is minutes #-cmin //The unit is seconds find / -name '*.xml' -a -amin -30 // means to find files that have been accessed within 30 minutes find / -name '*.xml' -a -atime +5 //mark to find files that have been accessed more than 5 days ago
Find files by file type
-type -f // normal file -d //directory file -l // link file -b //block device file -c //Character device file -p //pipe file -s //socket file find /tmp -type s //find socket file
Find by file size
-size find /tmp -size 2M //Files with a size of 2M find /tmp -size +2M //Find files larger than 2M in the /tmp directory find /tmp -size -2M //Find files smaller than 2M in the /tmp directory
Find files based on file permissions
-perm find /tmp -perm 755 //Find files whose permissions are 755 in the /tmp directory find /tmp -perm +222 //Indicates that as long as there is a matching write permission for a type of user (owner, group, others) find /tmp -perm -222 //Indicates that all categories of users must have write permissions
Constraint behavior after find command
find /tmp -perm 755 -ls //Display it with ls after finding it
find /tmp -perm 755 -ok //When executing the command after the search, ask the user whether to execute it
find /tmp -name '*.sh' -exec chmod u+x {} \; //Do not ask the user when executing the command after the search, directly execute '{}' Here means the found file
Practical use of some tricks
find /tmp -name '*.imi' |xargs chmod 700;
find /tmp -atime +30 –exec rm –rf {} \; //delete the found files that have not been accessed for more than 30 days
