dayspast: prints the number of days since the given date, useful with find
getip: prints IP for a given DNS name
getname: prints DNS name for a given IP
ipsort: sorts IPv4 addresses numerically by octets
subsize: prints the cumulative file size of each subdirectory of PWD or the specified directories
uc: prints a sorted list of the frequency of unique lines in stdin or a file or set of files
yesterday: prints yesterday's date, or the day before the provided date
