Check These Out

Run a command if today is the last day of the month
This is handy to just shove into a daily cron entry. If you do use cron, make sure to escape the %d with \%d or it will fail.

Find usb device
I often use it to find recently added ou removed device, or using find in /dev, or anything similar. Just run the command, plug the device, and wait to see him and only him

HourGlass
Displays an animated hourglass for x amount of seconds

Detect illegal access to kernel space, potentially useful for Meltdown detection
Based on capsule8 agent examples, not rigorously tested

World Cup Live Score
World Cup Live Score of the ongoing match. Alternative to have the live score with the match statistics: $ watch -n10 --no-title "w3m http://www.livescore.com/ |awk '/live [0-9H]+[^ ]/,/red cards/'"

Force logout after 24 hours idle
Shell timeout variables (TMOUT) can be very liberal about what is classified as 'activity', like having an editor open. This command string will terminate the login shell for an user with more than a day's idle time.

Convert seconds to [DD:][HH:]MM:SS
Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }
