Numbering
I'm trying to do a script that will look for a log file if it is already there change the name to another name.
I.E
if log.0 is there
rename to log.1
rename log.1 to log.2
rename log.2 to log.3 and so on.
Only thing is I got no idea where or what is the best command to use for this? I'm was thinking maybe mixing in sed and awk some how and doing it that way. As I said though I got no idea.
Perfect example the log files on /var/adm/log you got log.0 log.1 log.2 and so on these files have records and everytime a new log is needed the old log.X number moves up to the next number. Either it be 1 thru to 400.
If anyone can shed some light on this for me thanks a heap.

Would it be possible for a script to duplicate a file and incrementally number it?
File in: XXX_007_0580_xxxx_v0016.aep
File out: XXX_007_0580_xxxx_v0017.aep
If someone knows of a way I'd love to see it.
Thanks! (7 Replies)

I'm not really sure how to explain this but I will try. In the attached file if $4=$4 and $5="-" then the last record is 1 and the one above that is 2, etc...
However, $4=$4 and $5="-" then the first record is 1 and the one below that is 2, etc...

svcdumplog
svcdumplog(1m) svcdumplog(1m) NAME
svcdumplog - Prints contents of a binary serviceability log file SYNOPSIS
svcdumplog [-s num_of_entries] logfile OPTIONS
The -s flag tells svcdumplog to skip the first num_of_entries log entries before printing, where num_of_entries is a number. DESCRIPTION
The svcdumplog program will print the contents of a binary log file. DCE components log important information about their activities and state via the DCE serviceability interface. The log messages can be routed as desired via the dcecp log object. The messages can also be written in either binary or in text format (information about specify- ing message format can be found in svcroute(5)). When binary format has been specified for a component's messages, each log entry will be written as a binary record of data defined (in dce/svclog.h) as the contents of the serviceability prolog structure. The svcdumplog utility will print the contents of such a binary log file as readable text. RELATED INFORMATION
