I need to extract the last occurance of a pattern match. So far I've got the code below which extracts the first occurance. Any ideas how I can modify it so that it extracts the last?
I have a small query. I have a file containing the following lines
abcd<12></12>fdfgdf<12>sdfgfg<12>
sdfsdf<12></12>ytunfg<12>
hggfhf<12>rtysb<12>zdfgdfg<12>
Now I wish to delete ONLY the last occurance of string <12> from every lines of code. That mease my final output will be like this:... (7 Replies)
What I'm trying to do is, using awk, loading the log file into an array matching column 2, counting the match and finding the first occurance and last occurance of column 1 being it a date.

Hi,
I'm trying to match records using awk which contain only one occurance of my string, I know how to match one or more (+) but matching only one is eluding me without developing some convoluted bit of code. I was hoping there would be some simple pattern matching thing similar to '+' but... (9 Replies)
A PERL script that prints just the first occurrence of a string in a file and immediately exits (the string and the filename are the first and the second command line arguments; I used filehandle to open an input file). (1 Reply)

EXIGREP(8) System Manager's Manual EXIGREP(8)NAME
EXIGREP - Search Exim's main log
SYNOPSIS
exigrep [-l] pattern [log file] ...
DESCRIPTION
The exigrep utility is a Perl script that searches one or more main log files for entries that match a given pattern. When it finds a
match, it extracts all the log entries for the relevant message, not just those that match the pattern. Thus, exigrep can extract complete
log entries for a given message, or all mail for a given user, or for a given host, for example.
The -l flag means 'literal', that is, treat all characters in the pattern as standing for themselves. Otherwise the pattern must be a Perl
regular expression. The pattern match is case-insensitive. If no file names are given on the command line, the standard input is read.
If the location of a zcat command is known from the definition of ZCAT_COMMAND in Local/Makefile, exigrep automatically passes any file
whose name ends in COMPRESS_SUFFIX through zcat as it searches it.
