Need help with awk - how to read a content of a file from every file from file list
Hi Experts.
I need to list the file and the filename comes from the file ListOfFile.txt.
Basicly I have a filename "ListOfFile.txt" and it contain
Example of ListOfFile.txt
/home/Dave/Program/Tran1.P
/home/Dave/Program/Tran2.P
/home/Dave/Program/Tran3.P
/home/Dave/Program/Tran4.P
/home/Dave/Program/Tran5.P
Each file contain the same format on the first 2 lines about it's version.
I need to read the data from thesecond line column 3
Example of Tran1.P
/****************************
01122008 /home/Dave/Program/Tran1.P 10.05
****************************/
After I get the data from second line column 3 (10.05), I need to compare this data to the same filename that I found from file mapVersion.txt
Example of mapVersion.txt
Tran001.P|3.4
Tran020.P|4.2
Tran1.P|10.05
Tran12.P|4.11
Tran2.P|3.0
Tran3.P|10.5
Tran3A.P|12.3
Tran4.P|4.1
Tran5.P|1.2
I want to know if it's the same or not.
I know how to write script with ksh but I like to use awk to do this because I think it's faster than while loop.
Thanks in advance,
Tanit
