@YOGESH => Thanx for the suggestion. But since I don't have permissions to use CPAN modules, I am not able to try it out as well.
@CBKIHONG => Your solution works perfectly. Thanks a lot!

Hi,
Thanks for your quick suggestion. I grazed over the 'constant' pragma.
From the given link,
it's probably not correct to put a constant declaration inside of a conditional statement

Hi friends,

I am not sure if perl questions can be raised here. :rolleyes:
But I have a doubt if there is a way to do "#define" in perl, like in C.

Does anyone know if it is feasible (without...

And the one-liners (perl/grep) you gave, work great (still I'm trying to decipher the logic behind them though).
Thanks for your help.

Thanks

Hi,
I think I am mistaken.

Hi,
Thanx for the suggestions. I understand that the job can be done by different variations of scripts, but what I am eager about is "a single command/command pipe" which can do the job. If there...

Hi,
I've seen something similar to this while using "gnu grep". If you simply grep for something, only those lines containing the search-pattern will be displayed. But if u issue "gnu grep -1...

Hi,
Let me explain the problem clearly:
Let the entries in my file be:

Hi Percy,
I wonder why the command
sed '/hashcode/ d' logfile > temp ; mv -f temp logfile
wont be useful..!

Is that because it takes time to perform 'sed' and 'mv' operations. But in this...

Hi,
I dont know which platform your are working on. But of the query,


I guess for solaris 10 (Sun OS 5.10), there is a new amenity called "Completion Ports". I wonder if this may be useful...

As far as i know, this happens only under two situations:
- http server may not be running.
- cgi is not supported (i dont think this is common)

Hi,
I'm working on a solaris machine. The iptables idea is actually what i intended for. When I googled, I found that iptables are located at /etc/sysconfig/iptables. It is not present in my...

I missed out the key word actually, please excuse me. Actually, by TRY_AGAIN, i mean SERVFAIL case. I want the DNS server to return SERVFAIL case irrespective of the query. I went through 'named'...

Ah, I'm usually bad at explaining things. Sorry, but I'll give another try.
The actual need for me is to make the nameserver (dns_server) return 'Host not found, try again', irrespective of the IP...

Hi,
I was searching thro the topic and could not find a thread which zeroes in on the case i'm trying to simulate. Basically I have a need to simulate DNS Try again cases, without bringing the...

Hi all,
Thanks for your inputs.
@awk - the [:alnum] thing doesnt work out. It seems i have a older version of grep, since [:ascii] is also not working..
@reborg - your command indeed lists...

Thanks mschwage. But the command doesnt work out for me. Can you please let me know whether it worked out for u?

Thanks

Thanks Madhan!! That works fine.. (except for the "$length" instead of length)..
Can i know whether there is a command (instead of a script) to do this job?? an awk or perl or grep command??

Hi,
Can I know how to grep for lines with non-ascii characters in a file?

If not grep, at least can we do it with command-line perl or awk? I tried the [:ascii] functionality of perl, but...

Hi,
I am not sure what machine to connect :o
So I tried localhost and the machine name given by the command "hostname". I am quoting the responses from telnet: (IP address and hostname have...

Hi,

Hi all,
Thanks for your suggestions :) . I learnt a few concepts from your responses.
I didnt check this forum for a while, as I had finally resorted to generate my own directory listing...

Hi,
I suppose the following simple unix command pipe will do the work:
cat filename | sort | uniq -c | sort -nr

In case of more than one word in a line, the pipe would change to:
