I am running a grep query for searching a pattern, and the output is quite huge. I want only the last 200 lines to be displayed, and I am not sure if tail will do the trick (can tail read from std in/out instead of files?).
Please help me out. (1 Reply)

Hi.
I need to filter lines based upon matches in multiple tab-separated columns. For all matching occurrences in column 1, check the corresponding column 4. IF all column 4 entries are identical, discard all lines. If even one entry in column 4 is different, then keep all lines.
How can I... (5 Replies)

pdf::api2::basic::pdf::filter
PDF::API2::Basic::PDF::Filter(3pm) User Contributed Perl Documentation PDF::API2::Basic::PDF::Filter(3pm)NAME
PDF::API2::Basic::PDF::Filter - Abstract superclass for PDF stream filters
SYNOPSIS
$f = PDF::API2::Basic::PDF::Filter->new;
$str = $f->outfilt($str, 1);
print OUTFILE $str;
while (read(INFILE, $dat, 4096))
{ $store .= $f->infilt($dat, 0); }
$store .= $f->infilt("", 1);
DESCRIPTION
A Filter object contains state information for the process of outputting and inputting data through the filter. The precise state
information stored is up to the particular filter and may range from nothing to whole objects created and destroyed.
Each filter stores different state information for input and output and thus may handle one input filtering process and one output
filtering process at the same time.
METHODS
PDF::API2::Basic::PDF::Filter->new
Creates a new filter object with empty state information ready for processing data both input and output.
$dat = $f->infilt($str, $isend)
Filters from output to input the data. Notice that $isend == 0 implies that there is more data to come and so following it $f may contain
state information (usually due to the break-off point of $str not being tidy). Subsequent calls will incorporate this stored state
information.
$isend == 1 implies that there is no more data to follow. The final state of $f will be that the state information is empty. Error messages
are most likely to occur here since if there is required state information to be stored following this data, then that would imply an error
in the data.
$str = $f->outfilt($dat, $isend)
Filter stored data ready for output. Parallels "infilt".
