Essential Daily Commands

1. Simple File Download

# Basic download
wget https://example.com/file.zip

# Download and save with different name
wget -O newname.zip https://example.com/file.zip

# Download to specific directory
wget -P /sdcard/Download https://example.com/file.zip

# -O: output filename
# -P: directory prefix

Example:

wget -P /sdcard/Download https://releases.ubuntu.com/22.04/ubuntu-22.04-desktop-amd64.iso

2. Resume Interrupted Downloads

# Continue partially downloaded file
wget -c https://example.com/largefile.iso

# -c or --continue: resume getting partially-downloaded file

Example:

# First attempt (interrupted)
wget https://example.com/largefile.zip
# Resume later (same directory)
wget -c https://example.com/largefile.zip

Important: The file must be in the same directory where you run the command.

3. Download Multiple Files

# From a text file (one URL per line)
wget -i urls.txt

# With custom directory
wget -i urls.txt -P /sdcard/Download

# -i: input file with URLs

Example urls.txt:

https://example.com/file1.zip
https://example.com/file2.mp4
https://example.com/file3.pdf

Command:

wget -i urls.txt -P /sdcard/Download

4. Limit Download Speed

# Limit to 1MB/s
wget --limit-rate=1M https://example.com/file.zip

wget --limit-rate=500K https://example.com/file.zip

# Limit to 100KB/s for mobile data
wget --limit-rate=100K https://example.com/file.zip

Example:

# Download in background with speed limit
wget --limit-rate=500K -b https://example.com/largefile.iso

5. Background Download

# Download in background
wget -b https://example.com/file.zip

# Background with log file
wget -b -o download.log https://example.com/file.zip

Example:

wget -b -o download.log --limit-rate=1M -c https://example.com/largefile.iso

6. Download with Authentication

# HTTP Basic Authentication
wget --user=username --password=password https://example.com/file.zip

# Or using URL format
wget https://username:password@example.com/file.zip

# FTP Authentication
wget --ftp-user=username --ftp-password=password ftp://ftp.example.com/file.zip

# Read password from console (more secure)
wget --user=username --ask-password https://example.com/file.zip

Example:

wget --user=john --password=secret123 https://private.example.com/data.zip

7. Download with Retry Options

# Retry 10 times if download fails
wget --tries=10 https://example.com/file.zip

# Retry infinitely
wget --tries=inf https://example.com/file.zip

# Wait 30 seconds between retries

wget --no-proxy https://localhost/file.zip

Example:

wget -e use_proxy=yes -e http_proxy=192.168.1.1:8080 https://example.com/file.zip

15. Check if File Exists (Spider Mode)

# Check without downloading
wget --spider https://example.com/file.zip

# Check and show only errors
wget --spider -q https://example.com/file.zip
echo $?  # 0 if file exists, non-zero if error

# Check multiple URLs
wget --spider -i urls.txt

Example:

# Script to verify URLs

Troubleshooting

Issue 1: “Cannot write to ‘file.zip’ (Permission denied)”

Solution: Check directory permissions

# In Termux, request storage permission
termux-setup-storage

# Use /sdcard/Download
wget -P /sdcard/Download URL

Issue 2: “ERROR 403: Forbidden”

Solution: Server blocks wget user agent

# Use browser user agent
wget -U "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36" URL

Issue 3: “ERROR 404: Not Found”

Solution: Check URL with spider mode

# Verify URL exists
wget --spider URL

# Check for redirects
wget --spider --max-redirect=5 -S URL

Issue 4: “Unable to establish SSL connection”

Solution: Check certificate or skip verification

# Skip certificate check (use cautiously)
wget --no-check-certificate URL

# Or update CA certificates
pkg update ca-certificates

Issue 5: Download Speed Too Slow

Solution: Check if you’re being throttled

# Try different user agent
wget -U "Mozilla/5.0" URL

# Remove rate limiting from config
wget --limit-rate=0 URL

# Use multiple connections (not wget's forte, use aria2)

Issue 6: “Connection timed out”

Solution: Increase timeout and retries

wget --timeout=120 --tries=20 --waitretry=30 -c URL

Issue 7: Downloaded File is 0 bytes

Solution: Check if authentication is required

# Check with spider mode
wget --spider -S URL

# May need login
wget --save-cookies cookies.txt --post-data="user=X&pass=Y" LOGIN_URL
wget --load-cookies cookies.txt URL

Issue 8: Recursive Download Gets Too Much

Solution: Limit depth and domains

# Limit to depth 2
wget -r -l 2 -np URL

# Stay on same domain
wget -r -D example.com URL

# Exclude certain directories
wget -r -X /ads/,/temp/ URL

Best Practices

1. Always Use Resume Flag for Large Files

wget -c LARGE_FILE_URL

2. Be Polite to Servers

# Add delays and random waits
wget -r --wait=2 --random-wait --limit-rate=500K URL

3. Use Background Mode for Long Downloads

wget -bc -o download.log LARGE_FILE_URL

4. Save Bandwidth with Timestamping

# Only download if newer
wget -N URL

5. Use Config File for Consistent Settings

# Edit ~/.wgetrc once, benefit always
nano ~/.wgetrc

6. Verify Downloads

# Download checksum file
wget https://example.com/file.zip
wget https://example.com/file.zip.sha256

# Verify
sha256sum -c file.zip.sha256

7. Log Everything for Debugging

wget -o download.log -d URL  # -d for debug mode

8. Use Appropriate User Agents

# Don't pretend to be a browser if you're not
# But use modern UA if site blocks old clients
wget -U "Mozilla/5.0" URL

Useful Scripts

Script 1: Batch Downloader with Progress
