Hi,
I am a beginner at shell scripting, though I have several years of Oracle programming experience. Can anyone recommend a site where I can find some exercises on shell programming. Is there anywhere I can telnet as I dont have UNIX OS on my PC?
Thanks

I did an assignment for sh scripting back in november, and I found it quite fun learning. I would like to retain this knowledge as I'm pretty sure it was my only scripting assignment, from now on in my programming course we won't be doing any scripting apart from the typical makefile scripts.

I want to insert "Text" in each file as a place where I mentioned below "Insert Text Here". These files are something like news of newspaper. Generally, newspaper headlines contain one or two lines.

text::pdf::filter
Text::PDF::Filter(3pm) User Contributed Perl Documentation Text::PDF::Filter(3pm)NAME
PDF::Filter - Abstract superclass for PDF stream filters
SYNOPSIS
$f = Text::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 informa-
tion 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 filter-
ing process at the same time.
METHODS
Text::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 informa-
tion.
$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".
