I'm trying to iterate a UNIX awk script that returns min/max temperature data for each day from a monthly weather data file (01_weath.dat). The temperature data is held in $5. The temps are reported each minute so each day contains 1440 temperature enteries. The below code has gotten me as far as... (5 Replies)
I'm trying to write a script that accepts both arguments and options, e.g.
./script -h 1 -m 15 -s 30
or
./script
-h 1 -m 15 -s 30
I'd like for any of the arguments and options to be optional, and the option values should be numerals only. I've tried both getopt and getopts but I... (1 Reply)

one thing i was trying to figure out is if you can give people the option to choose what they want to do in a shell script. for example, let's just say that you have a simple shell script to install a couple of programs, can you make it to where you can press a certain key to install a certain...

ntp.conf
ntp.conf(5) File Formats Manual ntp.conf(5)Name
ntp.conf - Network Time Protocol configuration file
Description
The file is the configuration file for the Network Time Protocol (NTP) daemon, This file must be configured on your system before running
Any host names that you specify in the file must have an entry in the file, or an entry in the master database, if the database is being
served to your system by BIND/Hesiod or Yellow Pages.
The file has four entry formats:
trusting no
This entry guarantees that your system synchronizes only to the NTP servers identified in the peer and server entries specified. Dig-
ital recommends that all systems include the entry.
peer server
This entry identifies server as one of the NTP servers that your system trusts, and from which your system will accept time synchro-
nization. Your system may also provide time synchronization to this server. Servers can be identified by host name or internet
address.
NTP servers should be configured with entries.
server server
This entry identifies server as one of the NTP servers that your system trusts, and from which your system will accept time synchro-
nization. Your system can not provide time synchronization to this server. Servers can be identified by host name or internet
address.
NTP clients should be configured with entries.
peer /dev/null LOCL 1 -5 local
This entry identifies your system as a local reference clock. A local reference clock is the most accurate system clock available at
your site. If you receive time synchronization from the Internet NTP service, you should not include this entry on any of your sys-
tems. At most, one system in a set of nodes running should be identified as a local reference clock.
A host which specifies this entry should not specify any or entries.
Examples
This is a sample configuration file for an NTP client which receives time synchronization from the NTP servers: and Lines beginning with a
number sign (#) are comments.
#
# NTP Configuration File
# This file is mandatory for the ntpd daemon
#
#
#
# ** A L L **
#
# "trusting no" prevents this host from synchronizing
# to any host that is not listed below. It is recommended
# that all hosts include the line "trusting no".
#

#
#
# ** S E R V E R **
#
# If you are configuring a server, use "peer" entries to
# synchronize to other NTP servers. For example, server1,
# server2, and server3.
#
#peer server1
#peer server2
#peer server3
#
#
#
#
# ** C L I E N T **
#
# If you are configuring a client, use "server" entries to
# synchronize to NTP servers. For example, server1, server2,
# and server3.
#
server server1
server server2
server server3
#
#
#
# ** L O C A L R E F E R E N C E C L O C K **
#
# If you are configuring a local reference clock, include the
# following entry and the "trusting no" entry ONLY.
