Linux - how to search for find and locate files and directories?

Hi, I need to learn how to search by file name and directory name in a Linux terminal. What I was looking at is using the find a locate command, but I don't understand how to use it. How could I search for this:

Any file named *FILE3*. *
Exactly a file named FILE3.mkv

Any directory named *DIR2*
Exactly a directory named DIR2

Hi,

here are a few examples of how to use find and locate to search through terminal linux:

Find

# Any file named * FILE3 *. *
find /home -name "FILE3. *"

# Exactly the file named FILE3.mkv
find /home -name "FILE2.mkv"

# Any directory named * DIR2 *
find /home -type d -name "* DIR2 *"

# Exactly a directory named DIR2 (-name)
find /home - type d - name "DIR2"

# Ignore uppercase and lowercase letters (-iname)
find /home -type d-in "DIR2"

# Find files do not contain string
find /home \! -name "string"

# Files smaller than 500MB
find /home -size -500M

# Files larger than 7GB
find /home -size + 7G

# Find by file type (f - file, d - dir, b - block dev)
find /home - type l

# Find and delete * .tmp files
find /tmp -name "* .tmp" -delete

# Find by time
- modified 3 days ago = find /home + mtime 3
- accessed less than 2 days ago = find /home -atime -2
- changed metadata more than 7 days ago = find /home -ctime +7

# Find - more options are found by:
- -user
- -group
- -perm permissions

# Find - additional parameters
- search depth -maxdepth 4
- Follow the -L symbols
- Optimalization (1, 2, 3) of -O3

Locate

The locate command uses db, so searching should be faster than find, but it can't do that much like find
#Installation locate
apt install mlocate
#update db for locate
updatedb
# status db
locate -S
locate FILE3
locate -b FILE3
# Existing files only
locate -e FILE3
