Hi, just a couple of things that come to mind. Why do you have $( ... )? Does that even work. That should not need to be there (it would only work if there really is no output from those commands inside the command substitution), plus I would replace
with
. The fact that it sometimes does or does not work, may be due to buffering somewhere, so it works but not yet, not in real time. You can test this by having an extra tail -f and check what is written to the log at what point in time..
Why are you using tail and not tail -f? The tail buffer can also be a factor, it can be that the amount written exceeds what tail can display...
Another possibility is that by the time the script starts to do the tail the number of lines has changed and so some lines will never get read...
If you for some reason you need to use tail instead of tail -f, why don't you run the tail buffer straight through grep instead of line for line?
Does your system use udev? Because that would really be ideal for this application.

Hi,
Batch script gets executed without any error, but on execution some of the partial contents of the batch file gets appended at the end of the file which is currently in execution, hence the script tries to execute again for the second time , which should not happen.

shells
shells(4) File Formats shells(4)NAME
shells - shell database
SYNOPSIS
/etc/shells
DESCRIPTION
The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.
A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by the routines
which search the file. Blank lines are also ignored.
The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh,
/bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/pfcsh, /usr/bin/pfksh,
/usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh. Note that /etc/shells overrides the default list.
Invalid shells in /etc/shells may cause unexpected behavior (such as being unable to log in by way of ftp(1)).
