How do I restrict the output of the find command to just the file
name?

Here is the code:

thefile=$(find .  -newer trace_file_tmp -print)
 if [ -n "$thefile" ] ; then
       do something
 fi

Here is the directory it is operating in:  

-rwxr-xr-x   1 oracle     dba   611 Apr  9 11:16
ora_19842_elmcig76.trc
-rw-r--r--   1 oracle     dba   0 Apr 29 14:18   test
-rw-r--r--   1 oracle     dba   0 Apr 28 14:12   trace_file_tmp

With this code I am getting $thefile shown in debug mode:

thefile=.
./test
+ [ -n .
./test ]

With $thefile set to . or ./test it is not working like I need it.
How do I restrict find to only "test"?
Any suggestion will be appreciated.

thanks,

DJE

1.  Assuming that the file you want to find is always called "test", then
adding
        -name   test
    to the find command would find it
2.  Assuming that the problem is that it's also finding the file used in
the -newer test as well, you could add a pipe to grep to exclude it.
        find ....     |   grep  -v trace_file-tmp
    If the file name has to be variable, make it an argument to a script or
function

        Norm

pipe find's output through basename?

     Basename does not read stdin:

$ thefile=$(find .  -newer trace_file_tmp -print | basename)
basename: too few arguments
Try `basename --help' for more information

    What is not working? If you get an error, post it; if you get
    unexpected or undesired results, post the actual results as well
    as what you want.

    It's not clear what you want. Do you just want the one file? Or do
    you want the leading ./ stripped off? Or both?

    If you just want the one file, and it will always be called test,
    use that instead of .:

find test -newer trace_file_tmp -print

    If you want to strip the leading ./, and have the GNU version of
    find:

find -newer trace_file_tmp -printf "%f\n"

    Some versions of test (the command, not your file) have the -nt
    operator:

[ test -nt trace_file_tmp ] && echo test

I don't think you understood the question.  The problem isn't the
directory portion of the filename, the problem is that the output
contains two names, "." and "./test".

I suspect the solution is to use -type f in the find options, to keep it
from showing directories.

Simple, insert the '-type f' clause in your 'find' statement.e.g.,

    find . -type f -newer trace_file_tmp -print

tfile=test
if [ -n "`find $tfile -newer trace_file`" ]; then
  # ... do something
fi

Thanks for everybodys help.  I did this and it worked:

 thefile=$(find .  -type f  -newer trace_file_tmp -print)
    basename $thefile
    if [ -n "$thefile" ] ; then
       head -100 $thefile > ${OUTPUTFILE}
       echo  "New trace file $thefile  in ${UDUMPDIR}"  |
/usr/sbin/sendmail email  < ${OUTPUTFILE}
    fi

Use the -type f,  it was picking up a directory (i.e. .) And the
basename on the variable.  Since I am here:

1. How do I use a subject with sendmail?

2. How do I get a linefeed (i.e. \n ) in the echo to sendmail.  I have
put \n in the echo and tired printf and nothing has worked.

      ^^^^^^^^^^^^^^^^^^

This will only print the base name of the file, it does not change the value of
$thefile - is that what you want?

Try the mail or mailx command (depending on your platform) with the '-s
subject' option, unless you really have to use sendmail - it is much simpler.

If you need to use sendmail, you can add header entries before the 1st blank
line. For example:

 /usr/sbin/sendmail email  <<EOF Subject: here is my subject Cc:

$(cat ${OUTPUTFILE}) EOF

I'm not quite sure I understand, but I suspect you mean you want additional
linefeeds in the received email. If that is the case, I will assume you are
using MS Outlook and that it is "auto-formattingyour messages. If that is also
true, turn off auto-formatting in Outlook.
