Question
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:

Code:
dirs=`ls -d  *(#*`
echo $dirs

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.

NAME

       dircmp - directory comparison

SYNOPSIS

       n] dir1 dir2

DESCRIPTION

       examines  dir1  and  dir2 and generates various tabulated information about the contents of the directories.  Sorted listings of files that
       are unique to each directory are generated for all the options.	If no option is entered, a sorted list is output  indicating  whether  the
       filenames common to both directories have the same contents.

	      Compare the contents of files with the same name in
		      both  directories  and  output  a list telling what must be changed in the two files to bring them into agreement.  The list
		      format is described in diff(1).

	      Suppress messages about identical files.

	      Change the width of the output line to
		      n characters.  The default width is 72.

EXTERNAL INFLUENCES

   Environment Variables
       LC_COLLATE determines the order in which the output is sorted.

       If is not specified in the environment or is set to the empty string, the value of is used as a default.  If is not specified or is set	to
       the  empty  string,  a  default of ``C'' (see lang(5)) is used instead of If any internationalization variable contains an invalid setting,
       behaves as if all internationalization variables are set to ``C'' (see environ(5)).

   International Code Set Support
       Single- and multi-byte character code sets are supported.

EXAMPLES

       Compare the two directories and and produce a list of changes that would make the directories identical:
