This Wiki explains SUDO for TERMUX

Installing sudo in termux makes ur android device possible to execute a command as another user.

It will install ubuntu where u can use sudo...

After install it will create new folders:

ubuntu-fs
ubuntu-binds

Its gonna take cca 300+ mb...

In ubuntu-fs folder will be:

bin
etc
lib
mnt
proc
run
srv
tmp
var
boot
home
media
opt
root
sbin
sys
usr

So evry time u need doing sumthig as root user u can use this...

Ur prompt changes in:

root@localhost:~#

thats how u know u r in sudo mode.

! Note: It doesnt root ur device just makes possible u act as root...

Normaly when u try use sudo in termux its wont let u, showing this kinda msg:

 $ sudo --list
No superuser binary detected.
Are you rooted?

But when u run as root@localhost:~#

root@localhost:~# sudo --list

sudo: unable to resolve host localhost: Name or service not known      Matching Defaults entries for root on localhost:
    env_reset, mail_badpass,
    secure_path=/usr/local/sbin\:/usr/local/bin\:/usr/sbin\:/usr/bin\:/sbin\:/bin\:/snap/bin,
    use_pty                                                            
User root may run the following commands on localhost:
    (ALL : ALL) ALL

root@localhost:~#

sudo working...

WHAT sudo DO ?

Binary package “sudo” in ubuntu:

sudo

Provide limited super user privileges to specific users Sudo is a program designed to allow a sysadmin to give limited root privileges to users and log root activity. The basic philosophy is to give as few privileges as possible but still allow people to get their work done.

Many linux users allrdy know sudo, but if u r new with linux, sudo is mother for all kinda types of linuxes...

Todays allmost evry android device runs under linux, but if ur **no rooted no sudo ** use for u... termux app makes this possible...
