Hi Frank,

Sorry, I think I have uncompleted mentions of my question, here is the complete one, can you please help? :

I have binary files contain an ID Line as:

:
:
$Header: FNDSCMON.fmb 115.6 2000/01/11 10:26:10 pkm ship$
:
:

where the ID Line format is:
$Header: <File_Name> <Version> <Last_update_date_time> pkm ship$

In this Example:
File_Name = FNDSCMON.fmb
Version = 115.6
Last_update_date_time = 2000/01/11 10:26:10


I want to write a script to update the ID Line as:
File_Name = the file name
Version = version + 0.1
Last_update_date_time = current date_time

so, the new ID line should be show as:
:
:
$Header: <the file name> <version + 0.1> <current date_time> pkm ship$
:
:


- The line starts with "$Header:" and ends with "pkm ship$"
- The new line length have to be kept as same as the old line length (the whitespaces is adjustable)
- perl should be used for the replacment action (The files I want to change are binary files, using other command, such as, sed will make the file unusable)

Can you help how to write the script?


Many Thanks!
Victor Cheung
