Hi
I have 2 log files, each with a timestamp on the first 2 fields.
However, when I do a
awk '/ / {print $1,$2}' logs/x.log
on a log file,
it is complicated by the fact that I also get other non timestamp
column,

I like to generate a 3rd file after comparing 2 files with format like
the other 2 files but containing only the difference between 1st and

ie
suppose the file contains

I'm hoping to get in file3
2008-10-20 14:59:48,828 ...plus rest of line
2008-10-20 14:58:48,900 ...plus rest of line
I suppose I also need to read in the 1 field of the timestamp and
convert time to unix time to compare and then convert that unix time
to this timestamp format.
It looks like filecmp.cmp isn't enough to cope with my requirements
cuz it only gives a boolean value of 0 or 1,
not the actual print out of the differences between 2 files into a new
file.
Can this be done with Python quickly ?
Could someone be kind enough to show me steps to accomplish this ?
Any help is appreciated.

Hi there,
I am trying to compare two strings and get the differenc
in vbscript.
Example: Str1="This is a test text"
Str2="This is a fine test text but a little long"
I like to compare str1 with str2 and get the difference.
Above example the difference will be "fine" and "but a
little long"
How do I do that? A sample code would be apprciable.

I am new to Perl and new to this site. I have the same question that I keep seeing, but not finding an answer…why doesn’t the compare function work? I’ve been going at this for a while. My code is (I’m using ActviePerl 5.8.8 Build 822 on Microsoft WinXP):
use File::Compare;
if (compare("$file1" , "$file") == 0)
{
print REPORT_FILE "Pass - Files are the same\n";
}
else {print REPORT_FILE "Fail - Files are different\n"};

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
