Request for file read option in Unix shell scripting

Hi Friends,

I would like to read all the record from one txt file to other file txt

For example I have two txt file a.txt and b.txt. I need to read a.txt record by record and I need add the system date @ end of each record before moving it to b.txt. Could you please share the coding for this, I am very much new to this language. Thanks in advance.

For Example:
a.txt file contains the below record
Sample text record 1
Sample text record 2
Sample text record 3
Sample text record 4
Sample text record 5
Sample text record 6

After running my script it should generate b.txt as below
Sample 06/01/2011 text record 1
Sample 06/01/2011 text record 2
Sample 06/01/2011 text record 3
Sample 06/01/2011 text record 4
Sample 06/01/2011 text record 5
Sample 06/01/2011 text record 6

Regards,
Vinoth R

NAME
x2sys_merge - Merge an updated COEs tables SYNOPSIS
x2sys_merge -Amain_COElist.d -Mnew_COElist.d DESCRIPTION
x2sys_merge will read two crossovers data base and output the contents of the main one updated with the COEs in the second one. The second file should only contain updated COEs relatively to the first one. That is, it MUST NOT contain any new two tracks intersections (This point is NOT checked in the code). This program is useful when, for any good reason like file editing NAV correction or whatever, one had to recompute only the COEs between the edited files and the rest of the database. -A Specify the file main_COElist.d with the main crossover error data base. -M Specify the file new_COElist.d with the newly computed crossover error data base. OPTIONS
No space between the option flag and the associated arguments. EXAMPLES To update the main COE_data.txt with the new COEs estimations saved in the smaller COE_fresh.txt, try x2sys_merge -ACOE_data.txt -MCOE_fresh.txt > COE_updated.txt SEE ALSO
x2sys_binlist(1), x2sys_cross(1), x2sys_datalist(1), x2sys_get(1), x2sys_init(1), x2sys_list(1), x2sys_put(1), x2sys_report(1) GMT 4.5.7 15 Jul 2011 X2SYS_MERGE(1gmt)
