Two, find practical examples of command summary
======================================
First, based on the query file name
# find . -name tecmint.txt
# find /home -name tecmint.txt
# find /home -iname tecmint.txt
# find / -type d -name Tecmint
# find . -type f -name tecmint.php
# find . -type f -name "*.php"
Second, based on the query file permissions
# find . -type f -perm 0777 -print
# find / -type f ! -perm 777
# find / -perm 2644
# find / -perm 1551
# find / -perm /u=s
# find / -perm /g+s
# find / -perm /u=r
# find / -perm /a=x
# find / -type f -perm 0777 -print -exec chmod 644 {};
# find / -type d -perm 777 -print -exec chmod 755 {};
# find . -type f -name "tecmint.txt" -execrm -f {} ;
# find . -type f -name "*.txt" -exec rm -f{} ;
# find . -type f -name "*.mp3" -exec rm -f{} ;
# find /tmp -type f -empty
# find /tmp -type d -empty
# find /tmp -type f -name ".*"
Third, based on user and group query file
# find / -user root -name tecmint.txt
# find /home -user tecmint
# find /home -group developer
# find /home -user tecmint -iname "*.txt"
Fourth, time-based query file or directory
# find / -mtime 50
# find / -atime 50
# find / -mtime +50 –mtime -100
# find / -cmin -60
# find / -mmin -60
# find / -amin -60
Fifth, based on the size of the file or directory inquiries
# find / -size 50M
# find / -size +50M -size -100M
# find / -size +100M -exec rm -rf {} ;
# find / -type f -name *.mp3 -size +10M -exec rm {} ;
