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
