Command Cheat Sheet

Use This Guide When

Before You Run Anything

• Confirm that Termux came from a maintained source and that `pkg update` finishes without an error.
• Run one command at a time and stop at the first unexpected message.
• Keep the working project under the Termux home folder while installing or testing it.

Diagnostic Or Setup Commands

Read the block first, replace any example filename or folder, and run one line at a time from the location named by the guide.

pwd
ls -la
cd folder_name
mkdir new_folder
cp file.txt copy.txt
mv old.txt new.txt
python script.py

What The Commands Tell You

• `pwd` — Prints the current working directory.
• `ls -la` — Lists files, names, and permissions.

What Success Looks Like

• The command finishes without an error and you can explain which folder and file it used.
• Running the same minimal test a second time gives the same result.
• No reinstall or unrelated package change was needed.

Safe Next Steps

1. Verify the current folder with `pwd` and list exact filenames with `ls`.
2. Install only the package that the error actually names.
3. Run the smallest available test before starting the full project.
4. Save the working commands in the project README or a notes file.

Common Mistakes

• Copying Ubuntu or desktop Linux paths without checking whether they exist in Termux.
• Running an active project directly from shared Android storage.
• Pasting a long block again after one line has already failed.
