A BEGIN rule is executed once only, before the first input record is read. This is the reason why below code works as expected:- But in this code, FS is set only when the first input record is read:-
I would change the statement shown above in red to:
Quote:
But, in this code FS is set after each input record is read and split into fields. This uses the new FS to split input records after the 1st one; but the default field separator is used to split the 1st record before FS is set:
Other ways to make sure that the FS you want is used to split every input line include:

I put this here because it is a 'behavior' type question..
I seem to remember doing ls .* and getting all the .-files, like
.profile
.login
etc.
But ls .* doesn't do that, it lsts the contents of every .*-type subdirectory.
Is it supposed to?

the sed command:
sed 's/^*//' file
does not work on HP-UX :-( but it works fine on Linux,
content of file:

output should be:

Any ideas??
Thank you

Our comp-operator has come across a peculiar ‘feature'. We have this directory where we save all the reports that were generated for a particular department for only one calendar year.

Hi Experts
I am facing a weird issue while using print statement in awk. I have a text file with 3 fields shown below:
# cat f1

236,jih,3000

When I print the third column alone, I dont face any issue as shown below:

Aix 6.1, working with a nim master and nim_altmaster
both LPARS have access to the same data LUN, /nimdisk
I do realize the risks of having 2 servers access the same LUN, however it serves the purpose of being able to restore mksysb's to/from our DR site if necessary, at least in theory ;)

Hi there,
I am a bit puzzled by a weird behavior of Vi. I very simply would like to add increased numbers in some files. Since I have many thousands entries per file and many files, I would like to macro it in vi.
To do this, I enter the first number ("0001") on the first line and then yank... (4 Replies)

ntptrace
NTPTRACE(1) General Commands Manual NTPTRACE(1)NAME
ntptrace - trace a chain of NTP servers back to the primary source
SYNOPSIS
ntptrace [ -m max_hops ] [ -n ]
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. Here is an example of the output from ntptrace:
% ntptrace
localhost: stratum 4, offset 0.0019529, synch distance 0.144135
server2ozo.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): the host name, the host stratum, the time offset between that host and the local host (as
measured by ntptrace; this is why it is not always zero for "localhost"), the host synchronization distance, and (only for stratum-1
servers) the reference clock ID. All times are given in seconds. Note that the stratum is the server hop count to the primary source, while
the synchronization distance is the estimated error relative to the primary source. These terms are precisely defined in RFC-1305.
OPTIONS -m max_hops
Sets the number of server hops to follow (default = 99).
-n Turns off the printing of host names; instead, host IP addresses are given. This may be useful if a nameserver is down.
BUGS
This program makes no attempt to improve accuracy by doing multiple samples.
