Pull out multiple lines with grep patternfile
Hi,
I'm trying to get lines from a file using identifiers in the first two columns. I have used:
cat MasterFile.txt | grep -f Pattern.txt
and the lines I want display on screen. If I try to put them in a file the file is created but stays empty:
cat MasterFile.txt | grep -f Pattern.txt > output.txt
Also: If I use the whole pattern file (tested with 12 top lines from my pattern file to start) it doesn't even display on screen.....
Any ideas how I can do this? Very frustrating that the process seems to work but then hit the brick wall!!!

flow-rptfmt
flow-rptfmt(1) General Commands Manual flow-rptfmt(1)
NAME
flow-rptfmt -- Format the output of flow-report in ASCII or HTML
SYNOPSIS
flow-rptfmt [-hHnp] [-a alarm_time] [-f format] [-F fields] [-m max_lines] [-s sort_field]
DESCRIPTION
The flow-rptfmt utility processes the CSV output of flow-report into formatted ASCII or HTML. Sorting, maximum display lines, field fil-
ter, header display, and name substitution are supported during post processing. Additionally an alarm can be set for use in CGI scripts
to limit the CPU time of formatting.
OPTIONS
-a alarm_time
Exit after alarm_time seconds.
-f ascii|html
Set output format. Defaults to ASCII.
-F display_fields
Limit columns to display_fields
-h Help.
-H Display header information.
-m max_lines
Limit rows to max_lines.
-n Enable symbol table lookups.
-p Display in percent total form.
-s sort_field
Sort on sort_field. Prepend with + for ascending, - for descending sort.
EXAMPLES
Format the output of daily-ip-protocol.txt in ASCII. Display the ip-protocol and octets fields in percent total format with symbols.
Limit output to top 5 sorted by octets.
cat daily-ip-protocol.txt | flow-rptfmt -fascii -Fip-protocol,octets -p -n -m5
BUGS
Sorting could be faster. Percent totals could be faster. May not work with flow-report prior to 0.68.
