it depends.

what does the file look like? Give us its format.

Please post here a sample log file and the specific values you are looking for. Please be little more specific, if you want a general answer then I can tell you that to look for specific values in a specific log file there are many tools, like grep, sed, awk, perl, bash, ksh, sh whatsoever suits you.

Hi the log file looks like below:

Database Name AAALog BBB Log
#===================================================================#
XXXXXX S0000993.LOG S0000992.LOG
YYYYYY S0002549.LOG S0002549.LOG

I need to print only the difference of the S0000993.LOG and S0000992.LOG using Shell script. If we open 123.log then the output looks as above shown.

Can u suggest how to do this?
Thanks

Hi,

You can try using this with the previous command :

awk '$2 != $3' 123.log | sed -e s/S//g -e s/.LOG//g
