Shell Programming and Scripting

Can you please tell your exact requirement?

I want to run a script which filters out the contents of the file by:
Date
Time
String

But I want it to also filter out time ranges!

Here is log file:

2007/05/25 15:51:36.958117 sdfsdfsdf sdfdsfds-sdfds Trace name: STRINGA
sdfsdfsdfsdfsdfsdfsdfsdfsdff
sdfsdfsdfsdfsdfsdfsdfsdfsdf
dsfdsfsdfsdfsdfsdfsdfsdfsdfsdf

2007/05/25 15:56:06.670401 sdfsdfsdf sdfdsfds-sdfds Trace name: STRINGB
sdfsdfsdfsdfsdfsdfsdfsdfsdff
sdfsdfsdfsdfsdfsdfsdfsdfsdf
dsfdsfsdfsdfsdfsdfsdfsdfsdfsdf

2007/05/25 15:56:06.670683 sdfsdfsdf sdfdsfds-sdfds Trace name: STRINGB
sdfsdfsdfsdfsdfsdfsdfsdfsdff
sdfsdfsdfsdfsdfsdfsdfsdfsdf
dsfdsfsdfsdfsdfsdfsdfsdfsdfsdf

2007/05/25 16:07:12.145404 sdfsdfsdf sdfsdfsdf sdfdsfds-sdfdsfdsf Trace name: STRINGA
sdfsdfsdfsdfsdfsdfsdfsdfsdff
sdfsdfsdfsdfsdfsdfsdfsdfsdf
dsfdsfsdfsdfsdfsdfsdfsdfsdfsdf

2007/05/25 16:07:12.145701 sdfsdfsdf sdfsdfsdf sdfdsfds-sdfdsfdsf Trace name: STRINGA
sdfsdfsdfsdfsdfsdfsdfsdfsdff
sdfsdfsdfsdfsdfsdfsdfsdfsdf
dsfdsfsdfsdfsdfsdfsdfsdfsdfsdf

2007/04/14 16:07:12.145701 sdfsdfsdf sdfsdfsdf sdfdsfds-sdfdsfdsf Trace name: STRINGB
sdfsdfsdfsdfsdfsdfsdfsdfsdff
sdfsdfsdfsdfsdfsdfsdfsdfsdf
dsfdsfsdfsdfsdfsdfsdfsdfsdfsdf

So I want only to see text from 2007/05/25 16:05 - 2007/05/25 16:08 for STRINGB

Therefore I should only see the last entry in the log above. But I want to see all 4 lines.

Code:

while( <FILE> )
{
        if ( $_ ge "2007/05/25 16:05" && $_ le "2007/05/25 16:08" && /STRINGB/ ) {
                $results = $results . $_;
                $flag=3;
        }
        elsif ( $flag-- > 0 ) { $results = $results . $_; }
}

yeah, seems to be working, great.

Your a credit to this forum anbu23, thanks.

back again

Code:

while( <FILE> )
{
        if ( $_ ge "2007/05/25 16:05" && $_ le "2007/05/25 16:08" && /STRINGB/ ) {
                $results = $results . $_;
                $flag=3;
        }
        elsif ( $flag-- > 0 ) { $results = $results . $_; }
}

In the code above I want to add a 2nd search string, STRINGC. So I want to search for both strings if I give arguments for both, but if I dont give an argument for the 2nd string (STRINGC) then I only search for STRINGB.

You need to use 'ge' and 'le' instead of '>=' and '<=', respectively, since you are doing string (not numerical) comparisons.

I mean if I add STRINGC

Code:

if ( $_ ge "2007/05/25 16:05" && $_ le "2007/05/25 16:08" && /STRINGC/ && /STRINGB/ ) {

It doesnt work, what am i doing wrong?
