My first command :) I made this command to log public addresses of a virtual interface who connects random VPN servers around the world. Show Sample Output

Full command: for f in input/*; do BN=$(basename "$f"); ffmpeg -i "$f" -vn "temp/$BN.flac"; sox "temp/$BN.flac" "temp/$BN-cleaned.flac" noisered profile 0.3; ffmpeg -i "$f" -vcodec copy -an "temp/$BN-na.mp4"; ffmpeg -i "temp/$BN-na.mp4" -i "temp/$BN-cleaned.flac" "output/$BN"; done This was over the 255 character limit and I didn't feel like deliberately obfuscating it. 1. Create 'input', 'output' and 'temp' directories. 2. Place the files that you want to remove the hiss/static/general noise from in the input directory. 3. Generate a noise reduction profile with sox using 'sox an_input_file.mp4 -n trim x y noiseprof profile', where x and y indicates a range in seconds that only the sound you want to eliminate is present in. 4. Run the command.

Run a job in the background and prefix it's output with some string. This is particularly useful if you are running inside a docker container in a startup script (sue me, I'll run two jobs in a docker container if I want to) and you can run something like: /usr/sbin/nginx 2>&1 | awk '{print "[NGINX] " $0}' & /opt/jws-3.1/tomcat8/bin/catalina.sh run 2>&1 | awk '{print "[TOMCAT] " $0}' & while true; do ; done it can also be combined with tee to create a file log as well as a stdout log, for example if the script above where a script called "/bin/start-container.sh" then you could run /bin/start-container.sh | tee /var/log/containerlogs Show Sample Output
0nginx 2>&1 | awk '{print "[NGINX] " $0}' & -

Saves opening another console terminal (eg. CTRL+ALT+F[n]) or opening another remote terminal. Ctrl+Z pauses the current task and pushed it to the background, leaving you with a command prompt for those "Oh crap I forgot to change xyz before I ran that and it'll take forever if I Ctrl+C and start again..." situations. Typing 'fg' (shorthand for foreground, that's how I remember it) will resume the paused task. Show Sample Output
-1<CTRL+Z>; fg -
