Here's a good one. Looking to read through a file and then detect a certain string. Then check again sometime later to detect a different string and alert if that different string isn't found. While this string could appear anywhere in the file, I would only want the last found string to run this check on... example:
my $file = 'somefile.txt';
my $str1 = 'mystring1';
my $str2 = 'mystring2';
open F, $file
while (<F>)
{
Read file line by line, grab the last possible "str1" found in file, l
+ook for str2 from that point onward. If no str2 is found after str1
+was found, alert me
}
To clarify:
The only conditions set forth is only the LAST found "string1" needs to be detected. Then from that point foward, find "string2", ignoring everything prior to "string1". If "string2" is not found ON ANY LINE (same or new), yell something.
