Hi
I'm writing a script and I've put #!/bin/bash as the first line so that I can just type my scripts name 'whodate' at PS1 instead of ./whodate. This has suddenly stopped working for me. It used to be the case that I could start a script with #!/bin/bash and it would work, but for this script... (2 Replies)

ntptrace
ntptrace(1M) System Administration Commands ntptrace(1M)NAME
ntptrace - trace a chain of NTP hosts back to their master time source
SYNOPSIS
/usr/sbin/ntptrace [-vdn] [-r retries] [-t timeout] [server]
DESCRIPTION
ntptrace determines where a given Network Time Protocol (NTP) server gets its time from, and follows the chain of NTP servers back to
their master time source. If given no arguments, it starts with localhost.
OPTIONS
The following options are supported:
-d Turns on some debugging output.
-n Turns off the printing of host names; instead, host IP addresses are given. This may be necessary if a nameserver is down.
-r retries Sets the number of retransmission attempts for each host.
-t timeout Sets the retransmission timeout (in seconds); default = 2.
-v Prints verbose information about the NTP servers.
EXAMPLES
Example 1: Sample Output From the ntptrace Command
The following example shows the output from the ntptrace command:
% ntptrace
localhost: stratum 4, offset 0.0019529, synch distance 0.144135
server2.bozo.com: stratum 2, offset 0.0124263, synch distance 0.115784
usndh.edu: stratum 1, offset 0.0019298, synch distance 0.011993, refid 'WWVB'
On each line, the fields are (left to right):
o The server's host name
o The server's stratum
o The time offset between that server and the local host (as measured by ntptrace; this is why it is not always zero for localhost)
o The host's synchronization distance
o The reference clock ID (only for stratum-1 servers)
All times are given in seconds. Synchronization distance is a measure of the goodness of the clock's time.
