*shrug* I use ruby for my one liners all the time...

  % ruby -e 'p File.stat("/etc/passwd").mtime'

or more horribly

  % ruby -rdbi -e 'rows = []; DBI.connect("dbi:Pg:somedb:localhost", "postgres", "XXXXX") 
    { |dbi| dbi.prepare("select cisco, cisco_slot, cisco_port, liu_number, liu_port, floor
    from new_fiberx where cisco is not null  and cisco_slot is not null and  cisco_port is
    not null and  liu_number is not null and  liu_port is not null order by cisco, cisco_slot,
    cisco_port") { |sth| sth.execute; sth.each {|row|  rows << row.clone } ; rows.sort_by 
    { |row| [ row[0], row[1].to_i, row[2].to_i ] }.each { |row| next if row[0] == "" ; 
    printf "%s.%s/%d : %d.%s/%-5s\n", row[0], row[1], row[2], row[5], row[3], row[4] }}}'

etc...
