How to use sed to copy specific lines from a file using shell variables?
hello!
I am trying to use sed to copy specific set of lines from a file for which the starting and ending line numbers of the lines to be copied are stored in shell variables. How can i copy those lines?
if the input_file is something like this
Quote:
abc
def
ghi
jkl
mno
pqr
and if the following is the script
the output required is
Quote:
def
ghi
jkl
the shell variable a and b can presume different values accordingly. how can these shell variables be used in sed ? Can awk be used for this?

newline character is appended to the output. Specifies the number of lines to display Works exactly as -n lines. Obsolescent.
OPERANDS
Path name of the input file. If you do not specify a file, head reads standard input.

ENVIRONMENT VARIABLES
The following environment variables affect the execution of head: Provides a default value for the internationalization variables that are
unset or null. If LANG is unset or null, the corresponding value from the default locale is used. If any of the internationalization vari-
ables contain an invalid setting, the utility behaves as if none of the variables had been defined. If set to a non-empty string value,
overrides the values of all the other internationalization variables. Determines the locale for the interpretation of sequences of bytes
of text data as characters (for example, single-byte as opposed to multibyte characters in arguments and input files). Determines the
locale for the format and contents of diagnostic messages written to standard error. Determines the location of message catalogues for the
processing of LC_MESSAGES.
