Check These Out

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

Null a file with sudo

netstat with group by (ip adress)
Same as the rest, but handle IPv6 short IPs. Also, sort in the order that you're probably looking for.

Filter out all blank or commented (starting with #) lines

copy string to clipboard
Copy the current path. Use -selection clipboard to copy the string to clipboard.

Output system statistics every 5 seconds with timestamp
See man vmstat for information about the statistics. This does the same thing without the timestamp: $vmstat 5

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" }

generate a unique and secure password for every website that you login to
usage: sitepass MaStErPaSsWoRd example.com description: An admittedly excessive amount of hashing, but this will give you a pretty secure password, It also eliminates repeated characters and deletes itself from your command history. tr '!-~' 'P-~!-O' # this bit is rot47, kinda like rot13 but more nerdy rev # this avoids the first few bytes of gzip payload, and the magic bytes.

generate iso
