Generally what could be possiblilty of being ^@ added at the line 1
If I do :2 in commandline of log file it works fine.
I'm not sure I understand what you've written there; could you perhaps show us these command-lines you are using? The one that adds the junk, and also the one which works correctly using ":2" whatever that is?
Also, maybe it isn't important, but this logfile, it is a log created by what application? Or is it a common/usual Linux system generated log? In other words, what process(s) are writing to the logfile?
OK, so would it be fair to suppose that this problem has little or nothing to do with `logrotate`, but
is very likely to have something to do with that script:
/tools/jboss/jboss4/jboss-as/bin/run.sh
either directly, or indirectly via a problem or typo with one of those arguments provided to the script:
If you have double-and-triple checked that all these command-line arguments are correct, I would be then looking at the above mentioned script itself. Is there code inside the `run.sh` script which would generate literally the junk you get in the log? If so, examine the conditions required to cause the junk to be outputted.
Has this process ever worked correctly in the past? Without the crap in the logs? I.e. have you used this software before and it worked OK? If so, what's different this time?

How to delete the first line of a file without creatign the temporary file?
I have a log file which generates the junk character at the first line. I want to write a script to remove it without disturbing the file or creating the temporary file(
I tried this :
sed 1D test > tempfile.
But I dont want to create a temp file as jboss might be using that file.
Can it be done?
I need a script which will copy the log file(say A) in seperate new file(say B).
Remove the first line from B and copy it back to A.
Will it affect the log writing.
anyone who can help me with this script.
