$ cd /run/media/$USER/
for unmount -
  $ udisksctl unmount -b /dev/sda1

note: first check the targeted USB drive by running the command lsblk ---
# Rename (label) an exFAT drive
$ sudo exfatlabel /dev/sdX1 NewName

# Rename (label) an NTFS drive
$ sudo ntfslabel /dev/sdX1 NewName

# Only Apply LUKS Encryption (no format)
$ sudo cryptsetup luksFormat /dev/sdX1 && \ sudo cryptsetup open /dev/sdX1
secure_usb

# Only Format as exFAT (no encryption)
Way # 1️ Unmount the correct mountpoint sudo umount /run/media/zzz/mysam

#Close the LUKS mapper
$ sudo cryptsetup close luks-d13f7771-6d20-4707-aa85-ec55188e239a

#Force kernel + udev to refresh before
# formatting
$ sudo udevadm settle sudo partprobe /dev/sda

#Verify closure
$ lsblk -fp

#Format safely as exFAT
$ sudo mkfs.exfat -n MyB /dev/sda1

Way # 2 Unmount the correct mountpoint sudo umount /run/media/zzz/mysam
#Close the LUKS mapper
$ sudo cryptsetup close luks-d13f7771-6d20-4707-aa85-ec55188e239a

#Verify closure (mapper should disappear)
$ lsblk -fp

#Now it’s safe to format as exFAT
$ sudo mkfs.exfat -n MyB /dev/sda1

# Only Format as NTFS (no encryption)
$ sudo mkfs.ntfs -f -L MyUSB /dev/sdX1

note: while formating + luks is being attempted, if anything it says like -
Cannot exclusively open /dev/sda1, device in use - then simply run these
command below ---
$ lsblk-fp

indetify your drive and see if mounted and showing its capacity, is showing
then
$ sudo umount /run/media/zzz/FD86-090D (your drive name) then, $ lsblk -fp
now it should not show the drive's capacity or like that & now it's all okay
to go on...

# formatting a USB drive
--- "exFAT + LUKS"
$ sudo cryptsetup luksFormat /dev/sdX1 && sudo cryptsetup open /dev/sdX1
secure_usb && sudo mkfs.exfat -n mydrivesam /dev/mapper/secure_usb && sudo
cryptsetup close secure_usb

# formatting a USB drive
--- "NTFS + LUKS"
$ sudo cryptsetup luksFormat /dev/sdX1 && sudo cryptsetup open /dev/sdX1
secure_usb && sudo mkfs.ntfs -f -L Mydrivesand /dev/mapper/secure_usb &&
sudo cryptsetup close secure_usb

# To unlock and mount the drive

# To unlock and mount the drive

# To lock and mount --- "both exFAT & NTFS"
$ sudo umount /mnt/usb && sudo cryptsetup close secure_usb

# PARTITION MANAGEMENT TOOLKIT —

PART 1 — CREATE NEW PARTITIONS (WIPING OLD TABLE)
Identify your target drive
lsblk -fp
→ Example:
/dev/sda 128G └─/dev/sda1 vfat MyOldUSB
`/dev/sda` = the *whole* drive. Double-check before continuing.

Wipe old signatures (optional but safest)
$ sudo wipefs --all /dev/sda

Removes any old partition tables/filesystem traces. Destroys all data —
verify the device name first. Create new GPT partitions (modern layout)
$ sudo parted /dev/sda --script mklabel gpt \ mkpart primary 0% 28GB \ mkpart
primary 28GB 100%

Creates two partitions:
/dev/sda1` → 0–28 GB /dev/sda2` → 28 GB – end (~100 GB)
(For BIOS/MBR systems)
$ sudo parted /dev/sda --script mklabel msdos \ mkpart primary 0% 28GB \
mkpart primary 28GB 100%

Same result using an MBR label. Verify -
$ bash lsblk -fp
Expected:
/dev/sda ├─/dev/sda1 28G └─/dev/sda2 100G

(Optional) Format
**exFAT:**
$ sudo mkfs.exfat -n Part1 /dev/sda1 sudo mkfs.exfat -n Part2 /dev/sda2

**NTFS:**
$ sudo mkfs.ntfs -f -L Part1 /dev/sda1 sudo mkfs.ntfs -f -L Part2 /dev/sda2

(Optional) Encrypt with LUKS
Example – 28 GB partition:
$ sudo cryptsetup luksFormat /dev/sda1
$ sudo cryptsetup open /dev/sda1 secure_usb1
$ sudo mkfs.exfat -n MySecure1 /dev/mapper/secure_usb1
$ sudo cryptsetup close secure_usb1

Example – 100 GB partition:
$ sudo cryptsetup luksFormat /dev/sda2
$ sudo cryptsetup open /dev/sda2 secure_usb2
$ sudo mkfs.exfat -n MySecure2 /dev/mapper/secure_usb2
$ sudo cryptsetup close secure_usb2

CREATE NEW PARTITION WITHOUT LOSING EXISTING NTFS DATA**
*(Non-destructive, NTFS-only; exFAT cannot be safely resized.)*
$ lsblk -fp
→ Find something like `/dev/sda1 ntfs MyDrive`.
Unmount -
$ sudo umount /dev/sda1
Check filesystem sudo ntfsfix /dev/sda1

Shrink filesystem to 100 GB sudo ntfsresize --size 100G /dev/sda1
Shrinks only the filesystem, not the partition boundary.
Resize partition boundary to match
$ sudo parted /dev/sda (parted) print (parted) resizepart 1 100GB (parted)

quit

Create new partition in free space (~28 GB)
$ sudo parted /dev/sda --script mkpart primary 100GB 100%

Format the new partition
**exFAT:**
$ sudo mkfs.exfat -n NewPart /dev/sda2

**NTFS:**
$ sudo mkfs.ntfs -f -L NewPart /dev/sda2

Verify final layout
$ lsblk -fp
Expected:
/dev/sda1 ntfs MyDrive /dev/sda2 exfat NewPart

FULL COMMAND SUMMARY
Identify lsblk -fp
# --- If wiping & repartitioning
sudo wipefs --all /dev/sda sudo parted /dev/sda --script mklabel gpt mkpart
primary 0% 28GB mkpart primary 28GB 100%
# --- If keeping data (NTFS shrink)
sudo umount /dev/sda1 sudo ntfsfix /dev/sda1 sudo ntfsresize --size 100G
/dev/sda1 sudo parted /dev/sda resizepart 1 100GB sudo parted /dev/sda
--script mkpart primary 100GB 100%
# --- Format new partition
sudo mkfs.exfat -n NewPart /dev/sda2 # or mkfs.ntfs -f -L NewPart /dev/sda2

privacy.resistfingerprinting = true

3DES Cypher:
3DES has known security flaws

security.ssl3.rsa_des_ede3_sha = false

Require Safe Negotiation:  Optimize SSL

security.ssl.require_safe_negotiation = true

Disable TLS 1.0, 1.1

security.tls.version.min = 3
enables TLS 1.3
tls.version.max = 4

Disable 0 round trip time to better secure your forward secrecy

browser.cache.disk_cache_ssl = false
browser.cache.memory.enable = false
browser.cache.offline.enable = false
browser.cache.insecure.enable = false

Disable geolocation services
geo.enabled = false

Disable plugin scanning.
Can improve functionality, as some sites scan for adblockers and script blockers. Should be used even on non-hardened firefox.

plugin.scan.plid.all = false

Disable ALL telemetery

browser.newtabpage.activity-stream.feeds.telemetry browser.newtabpage.activity-stream.telemetry = false

Disable WebGL
Allows direct access to GPU.
webgl.disabled = true

Enable first-party isolation
Prevents browsers from making requests outside of the primary domain of the website. Prevents supercookies. may cause websites that rely on 3rd party scripts and libraries to break, however those are generally only used for tracking so fuck em anyway.

### Get manual of anything-
$ man -(programe name) $ man man $ man cd $ info $ info ls $ info newsboat $
sensors

### Knwoing system's OSs specs or info:
$ uname -a $ uname --help

then,
$ uname -(there wil be mentioned many letters to know a specific info in the
help section)

### Storage related-

### Remove .trsh1000 folders items from your USB drive---
$ sudo rm -rf /run/media/$USER/YOUR_USB_NAME/.Trash-1000/*

replace "YOUR_USB_NAME" with your actual USB name, to know exactly run the
command ---
$ ls /run/media/$USER/

### For secure file deletion use -
shred (file name) command also can be used shred -u (file naem) for both
shredding and then delete the file. Additionaly,

$ sudo dd if=/dev/urandom of=/mnt/usb/junk status=progress (gotta check
again)

### Remove BG from pretty much any images- (gotta verify again)
$ convert -transparent (BG color, namenly white, red, blue, black) (file
name)

$ convert -transparent (BG color, namenly white, red, blue, black) -fuzz
(60/50...%)w(or without w) (file name)

$ convert -trim -transparent (BG color, namenly white, red, blue, black)
-fuzz (file name)


### CLI method for stabilizing any videos -

----------------------------------- Steganography
### Steghide:

With Images
To embed a secret file in an Image file use this Command:
$ steghide embed -cf (image file's full name within extension) -ef
(secretfile, the file that wanna hide inside the image file)

To extract the secret file use this command:
$ steghide extract -sf (image file's full name within extension)

With Audio
To embed a secret file in an Audio file use this Command:
$ steghide embed -cf (Audio file's full name within extension) -ef
(secretfile, the file that wanna hide inside the image file)

To extract the secret file use this command:
$ steghide extract -sf (Audio file's full name within extension)

### Screen mirroring:

for wireless open Terminal and ---
$ adb devices
it should shows like this:

Freedom 2 is the freedom to help your neighbor; that is, the freedom to
make and distribute exact copies of the program whenever you want.
freedom 3 is the freedom to contribute to your community; that is,
the freedom to make and distribute copies of your modified versions of
the program.

With these four freedoms a program is Free Software because the social
system for its use and distribution is an ethical system that respects
everyone's freedom and the freedom of the community of users.
Software must be Free because we all deserve freedom, we all deserve to
be allowed to participate in a free community.


Please call the system “GNU+Linux,” or “GNU/Linux.” Please avoid using
the term “open” or “open source” as a substitute for “free software.”
They don't say libre, they say “open source.” That term was coined by
the people like Mr Torvalds who would prefer that these ethical issues
don't get raised. Also, “FOSS” The term “FOSS,” meaning “Free and Open
Source Software,” was coined as a wayto be neutral between free software
and open source Instead of FOSS, say, free software or free (libre) software.
