Hi Driver,
This is not a HOMEWORK question.
Head has one option -n to display first n number of lines in a file.
Which won't serve my purpose.
Tail does samething from opposite direction and hence no use either.
I wanted a combination to get a range of lines.
More specifically, I wanted to extract a function block from the file.
( I have around 20 similar programs written in perl and all have few common functions. I need to change these functions now. In order to verify I didn't want to open again using "vi". Hence the need was to a have look at the function block in all files and verify the changes.)
I didn't get what Kelam_Magnus is saying.
I have gone through the link given on Vi few times long back and thanks for reminding me on the same. I will go through the page again as it gives lot of pleasure in reading the same.
Thanks,
Sharath

cdtool2cddb
CDTOOL2CDDB(1) User Commands CDTOOL2CDDB(1)
NAME
cdtool2cddb - convert .cdtooldb file to set of CDDB files
SYNOPSIS
cdtool2cddb [-rvx] [-d dir] [-l len] [input...]
DESCRIPTION
cdtool2cddb converts one or more .cdtooldb files to CDDB-format files suitable for using with many CD player applications. The output is a
set of files, each named for the 32-bit hexadecimal CDDB ID number of a given audio CD. These files are placed in the current directory
unless -d is specified.
OPTIONS
-d directory
Specify the output directory. This is where the 8-digit output filenames go. There will be one file for each CD definition in your
.cdtooldb file(s).
-l length
Specify the maximum line length for the output file. Comment lines may be any length, but the CDDB format specifies that data lines
must wrap at 76 characters. Thus, this is the default for cdtool2cddb, but you may change it if you wish.
-r At least one CD player application (groovycd) requires lines of its CDDB files to end with CR-LF, because they come over the network
that way. The -r option tells cdtool2cddb to output such lines; otherwise lines will end with LF only.
-v Increment the verbosity level.
-x Use an alternate identification string in the output file. If you wish to upload a CDDB file to a CDDB server via e-mail, the
server will probably check the ID string in the file to make sure it is from a "trusted" CD player application. cdtool is not
trusted, but xmcd is, so the -x option pretends we are xmcd.
FILES
~/.cdtooldb
A typical cdtooldb input file
/var/lib/cddb/misc, ~/.groovycd
Typical output directories (see -d).
