Hi Scrutinizer,

Thanks for the quick reply read -A worked well for korn shell , i am unable to get the code properly. How to frame the variable loop to get each value from a line in a file.

like :
Code:
LINE_1_VALUE_1=111
LINE_2_VALUE_2=22
...
..
END OF LINE
LINE_2_VALUE_1=dd
LINE_2_VALUE_2=ee
...
...
..

Please give a gist or an idea/approach, if possible.

Thanks,
Regards,
karthikram

SHCOMP(1)						       Korn shell utilities							 SHCOMP(1)

NAME
shcomp - compile a shell script SYNOPSIS
shcomp [ options ] [infile [outfile]] DESCRIPTION
Unless -D is specified, shcomp takes a shell script, infile, and creates a binary format file, outfile, that ksh can read and execute with the same effect as the original script. Since aliases are processed as the script is read, alias definitions whose value requires variable expansion will not work correctly. If -D is specified, all double quoted strings that are preceded by $ are output. These are the messages that need to be translated to locale specific versions for internationalization. If outfile is omitted, then the results will be written to standard output. If infile is also omitted, the shell script will be read from standard input. OPTIONS
[D dictionary] Generate a list of strings that need to be placed in a message catalog for internationalization. [n noexec] Displays warn- ing messages for obsolete or non-conforming constructs. [v verbose] Displays input from infile onto standard error as it reads it. EXIT STATUS
0 Successful completion. >0 An error occurred. SEE ALSO
