This has saved me many times while debugging timeout issues to "too many open files" issues. A high number of the order of thousand, indicates that somewhere connection is not being closed properly.

sox (SOund eXchange) can capture the system audio be it a browser playing youtube or from hardware mic and can pipe it to ffmpeg which encodes it into flv and send it over rtmp.

Tested using Red5 rtmp server.

diskutil info /dev/disk0 | grep 'Device / Media Name'
awk '{for (i=9;i<=NF;i++) {printf "%s",$i; printf "%s", " ";}; printf "\n"}'

It'll print the file names preserving the spaces in their names and adding new line after every new filename.

I wrote this to quickly find out how many files in any directory is owned by a particular user. This can be extended using pipe and grep to do much more.

This one is tried and tested for Ubuntu 12.04. Works great for tailing any file over http.

for file in `ls *.png`;do convert $file -resize 65% new_$file; done
load=`uptime|awk -F',' '{print $3}'|awk '{print $3}'`; if [[ $(echo "if ($load > 1.0) 1 else 0" | bc) -eq 1 ]]; then notify-send "Load $load";fi

I run this via crontab every one minute on my machine occasionally to see if a process is eating up my system's resources.
