Top Forums Shell Programming and Scripting get last section from large logfile Post 51435 by zazzybob on Wednesday 19th of May 2004 05:23:01 PM

print $NR wouldn't have the expected result, it would print the field at the position referenced by the Number of Records (NR) variable, which means that if you've more records than fields, you'll get nothing. For example if there were 6 records, then NR would be set to 6, thus "print $NR" would evaluate to "print $6" hence the sixth field would be printed.

The shortest version of this is (from the command line):

Code:
awk 'BEGIN {RS="===*\n";FS="\n"}{result=$0} END {print result}' my_log_file

........ I think.......
