find command which helps us in finding lot of stuff,
Syntax: find <path> <options> <regex/name> find . -name flag1.txt: find the file named “flag1.txt” in the current directory
find /home -name flag1.txt : find the file names “flag1.txt” in the /home directory
find / -type d -name config : find the directory named config under “/”
find / -type f -perm 0777 : find files with the 777 permissions (files readable, writable, and executable by all users)
find / -perm a=x : find executable files
find /home -user frank : find all files for user “frank” under “/home”
find / -mtime 10 : find files that were modified in the last 10 days
find / -atime 10 : find files that were accessed in the last 10 day
find / -cmin -60 : find files changed within the last hour (60 minutes)
find / -amin -60 : find files accesses within the last hour (60 minutes)
find / -size 50M : find files with a 50 MB size
find / -writable -type d 2>/dev/null : Find world-writeable folders
find / -perm -222 -type d 2>/dev/null : Find world-writeable folders
find / -perm -o w -type d 2>/dev/null : Find world-writeable folders
find / -perm -o x -type d 2>/dev/null : Find world-executable folders
We can also find programming languages and supported languages: find / -name perl*, find / -name python*, find / -name gcc* ...etc
find / -perm -u=s -type f 2>/dev/null : Find files with the SUID bit, which allows us to run the file with a higher privilege level than the current user. This is important!
We can even make use of "grep", "locate", "sort"...etc
