Termux Shell Fundamentals

The Termux shell is the operational core of the academy. It lets you navigate files, inspect text, run Python and automate repeatable defensive work from Android.

Filesystem orientation

$HOME/                 private Termux home
$PREFIX/bin/           installed commands
~/storage/shared/      Android shared storage, when enabled
~/.dedsec-smartphone-academy/     academy state and workspaces

Core commands

pwd
ls -la
cd ~/dedsec-academy
mkdir -p notes evidence reports
cp source.txt evidence/source-copy.txt
mv draft.txt reports/final.txt
find . -type f
grep -Rni 'error' .

Permissions and execution

chmod +x script.sh
./script.sh
ls -l script.sh

Never run an unfamiliar script merely because it is executable. Read it first, use a disposable copy and avoid granting Android storage permission unless the task needs it.
