getting around with commands on linux: find

finding files

find PLACE_TO_LOOK -name PATTERN -fstype DO_NOT_SEARCH_HERE

-xdev -mount. -ftstype TYPE
-> leaves out other filesystems, meaning other partitions, say if /usr/local is on one and you're searching /usr

-fstype is usually used with -prune to avoid searching remote filesystems. -> searchs the directories and sub-directories

find /usr/src -name '*.c' -size +100K -print
-> prints the names of all files in /usr/src whose names end in .c and that are larger than 100 Kb.

find /usr/include -name "*.h" -exec grep 'tcp' {} \; -print

find . -xdev -type f \( -mtime 0 -or -mtime 1 \) -exec cp -aPv "{}" $dest.new \;

find / -nouser -o -nogroup -print:locate files that have no user or no group

find / -perm -2 ! -type l -ls: locates all world-writable files on the system

find / -type f \( -perm -04000 -o -perm -02000 \): finds all suid and guid files

find . -type f -exec grep -l 192.168.100.3 {} \; -> (finds dhcp server on a linux box from a windows machine)

-atime 7 -- > finds all files which have not been modified in atleast 7 days

-type d -- > finds directories

-type f -- > finds files

-type size e.g. 100k

-type l -> is a symbolic link

-follow
-> dereference the symbolic link

find /usr/include -type -f -follow -name "*.h" | xargs grep -E1 `#define *PAGE_OFFSET_RAW`
-> searches in the results from find for lines containing PAGE_OFFSET_RAW

find . -type f -print | xargs grep -l WARNING

locate searches special file name databases for file names that match patterns
