Introduction

Output redirection lets you save command results to TXT files. It is useful for logs, diagnostics and documentation.

Essential operators

• > overwrite file
• >> append
• 2> redirect errors
• 2>&1 merge output + errors

Quick example: ping

ping 192.168.0.1 > ping.txt
ping -n 4 8.8.8.8 > ping_result.txt
ping -t 8.8.8.8 > ping_continuous.txt

Example: ipconfig

ipconfig /all > ipconfig.txt
ipconfig > ipconfig_basic.txt
ipconfig /displaydns > dns_cache.txt
echo %date% %time% >> ipconfig.txt && ipconfig /all >> ipconfig.txt

Useful network commands

netstat -an > active_connections.txt
route print > routing_table.txt
systeminfo > system_info.txt
tracert google.com > traceroute.txt

Timestamped logs

echo [%date% %time%] ping google.com >> net_log.txt
ping google.com >> net_log.txt

Other locations

ping google.com > C:\Logs\ping.txt
ping google.com > "%USERPROFILE%\Documents\ping.txt"
mkdir C:\Monitoring
ping google.com > C:\Monitoring\ping.txt

Automation with .bat

@echo off
ipconfig /all > ip_diagnostics.txt
ping -n 4 8.8.8.8 > connectivity.txt
nslookup google.com > dns_test.txt

Conclusion

With these operators you can create logs and diagnostics quickly.
