Sorry for not making myself clear:
The actual names of the directories are:
"File Reader (#53)"
"CSV Writer (#47)"
"Scorer (#22)"
but to just make it simple we can rename them to:
"dir1 (#29)"
"dir2 (#45)"
"dir3 (#23)"
I have gathered all of the directory names using the following code:
output:
"dir1 (#29)"
"dir2 (#45)"
"dir3 (#23)"
Now I would like use SED to return the number portion of the desired directory name. For example, I would like to be able to input the string "dir1". Using the list of directories that I have already generated and stored into variable $dirs I want the output to be 29. Preferably if this value could be stored in a variable also would be great. Alternatively, if I was looking for "dir2" from the list of dirs, the desired output would be 45. Likewise for "dir3" where the desired output would be 23.
The number is part of the directory's name. All I am trying to do is cut the desired directory name and only return the number portion.

Try this:
Code:
sed -e '/File Reader/!d' -e 's/.*#\(.*\))"/\1/g' fileread.txt
this did not work and returned the following message:
sed: can't read fileread.txt: No such file or directory
I am not sure why it is looking for an input file. No input file is needed.
Hi,
Is there any way to traverse the file once and look for the following conditions in one sweep instead of going over the file 3 times with different search criteria......
sed -n '/^ORA-07445/ p' /tmp/t$$ > ${OERRFILE}
sed -n '/^ORA-00600/ p' /tmp/t$$ >> ${OERRFILE}

graph::reader
Graph::Reader(3pm) User Contributed Perl Documentation Graph::Reader(3pm)NAME
Graph::Reader - base class for Graph file format readers
SYNOPSIS
package Graph::Reader::MyFormat;
use Graph::Reader;
use vars qw(@ISA);
@ISA = qw(Graph::Reader);
sub _read_graph
{
my ($self, $graph, $FILE) = @_;
# read $FILE and populate $graph
}
DESCRIPTION
Graph::Reader is a base class for Graph file format readers. A particular subclass of Graph::Reader will handle a specific file format,
and generate a Graph, represented using Jarkko Hietaniemi's Graph class.
You should never create an instance of this class yourself, it is only meant for subclassing. If you try to create an instance of
Graph::Reader, the constructor will throw an exception.
METHODS
new()
Constructor - generate a new reader instance. This is a virtual method, or whatever the correct lingo is. You're not meant to call this on
the base class, it is inherited by the subclasses. Ie if you do something like:
$reader = Graph::Reader->new();
It will throw an exception.
read_graph()
Read a graph from the specified file:
$graph = $reader->read_graph($file);
The $file argument can either be a filename, or a filehandle for a previously opened file.
SUBCLASSING
To create your own graph format reader, create a module which subclasses Graph::Reader. For example, suppose DGF is a directed graph format
- create a Graph::Reader::DGF module, with the following structure:
package Graph::Reader::DGF;
use Graph::Reader;
use vars qw(@ISA);
@ISA = qw(Graph::Reader);
sub _read_graph
{
my $self = shift;
my $graph = shift;
my $FILE = shift;
while (<$FILE>)
{
}
return 1;
}
1;
Note the leading underscore on the _read_graph() method. The base class provides the public method, and invokes the private method which
you're expected to provide, as above.
If you want to perform additional initialisation at construction time, you can provide an _init() method, which will be invoked by the base
class's constructor. You should invoke the superclass's initialiser as well, as follows:
sub _init
{
my $self = shift;
$self->SUPER::_init();
# your initialisation here
}
Someone can then use your class as follows:
use Graph::Reader::DGF;
$reader = Graph::Reader::DGF->new();
$graph = $reader->read_graph('foo.dgf');
