Hi ,

I have one main script called script1.sh which contains the cotennts below. this script wil search for the existence of files in a particular directory and if one file is finidin it wil send to another server . this is the basic functionality
the script1.sh is given below


#Al the directiory locations wil be mentinedin the first

# Trace output function
trace ()
{
if [ $TRACE ]
then
DATE=`date +"%Y-%m-%d %X"`
echo "$DATE: $1" >> $TRACEFILE
fi
}

trace "Script $0 started"

# First find all alarm files to import at start
FILES="`find $ALARM_FILES_DIR -type f`"

# Loop forever and import files
while [ true ]
do
loop=`expr $loop + 1`

# cat the files to a text file
if [ "$FILES" != "" ]
then
FILES_SORTED="`ls -rt $FILES`"
trace "Alarm files to import:\n$FILES_SORTED"

for i in $FILES_SORTED
do
cat $i>export1.txt

username=***
password=***

expect -c "
# exp_internal 1 # uncomment for debugging

spawn /usr/bin/scp export1.txt ***@ipaddress:/location

expect {
"*password:*" { send $password\r\n; interact }
eof { exit }

}
exit
"
/export/home/netcool/rohith/script.sh
rm -rf export1.txt

echo
done

LATEST="$i"
SENDHB=false
else
trace "No new alarm files to import"
SENDHB=true
fi

trace "Latest alarm file imported: $LATEST"

#
# If the latest file sent still exists then find newer files, otherwise find all files
if [ -f "$LATEST" ]
then
FILES="`find $ALARM_FILES_DIR -newer $LATEST -type f`"
else
FILES="`find $ALARM_FILES_DIR -type f`"
fi
# Modify sleep time (in seconds) as needed below
sleep 2

done

bzexe

BZEXE(1)						      General Commands Manual							  BZEXE(1)

NAME

       bzexe - compress executable files in place

SYNOPSIS

       bzexe [ name ...  ]

DESCRIPTION

       The  bzexe  utility  allows you to compress executables in place and have them automatically uncompress and execute when you run them (at a
       penalty in performance).  For example if you execute ``bzexe /bin/cat'' it will create the following two files:
	   -r-xr-xr-x  1 root  bin   9644 Feb 11 11:16 /bin/cat
	   -r-xr-xr-x  1 bin   bin  24576 Nov 23 13:21 /bin/cat~
       /bin/cat~ is the original file and /bin/cat is the self-uncompressing executable file.  You can remove /bin/cat~ once  you  are	sure  that
       /bin/cat works properly.

       This utility is most useful on systems with very small disks.

OPTIONS

       -d     Decompress the given executables instead of compressing them.

SEE ALSO

       bzip2(1), znew(1), zmore(1), zcmp(1), zforce(1)

CAVEATS

       The  compressed	executable  is a shell script. This may create some security holes. In particular, the compressed executable relies on the
       PATH environment variable to find gzip and some other utilities (tail, chmod, ln, sleep).

BUGS

       bzexe attempts to retain the original file attributes on the compressed executable, but you may have to fix them manually  in  some  cases,
       using chmod or chown.
