In .bash_profile:

Yes I have already entried in .bash_profile as
export INSTALL_BASEPATH=/vol2/RAORV_HOME

and I check it if I print the value from shell script it works well in cp command it's not working

When you post code, please wrap it in [code] tags.

Code:
tempURL=`cat PropertiesFileURL_unix.txt|tr '\n' ' '|tr -d '\r'`
urlCount=(`echo "$tempURL" | sed 's/[^ ]//g' | wc -c` ) 
urlCount=`expr $urlCount - 1`


You have six external commands in three lines. You need no more than 2. (You never need expr; the shell can do integer arithmetic.)

It's not clear exactly what you are counting, so it's hard to recommend any code.
Quote:
Code:
echo "urlCount------------->"$urlCount
URL=( $tempURL )


Ah!

I think everything up to this point can be replaced with:

Code:
oIFS=$IFS
IFS='
'
URL=( $(tr -d '\r' < PropertiesFileURL_unix.txt) )
IFS=$oOFS
urlCount=${#URL[@]}

See? One external command!
Quote:
Code:
distributionName=`echo $INSTALL_BASEPATH|awk -F "/" '{print $NF}'`
ratingdirName=`echo $INSTALL_RATPATH|awk -F "/" '{print $NF}'`


You don't need awk:

Code:
distributionName=${INSTALL_BASEPATH##*/}
ratingdirName=${INSTALL_RATPATH##*/}

Quote:
Code:
for(( j =0; j< $urlCount ; j++ ))
do
    echo -e "{URL[$j]}------------->"${URL[j]}
    serverName=`echo ${URL[$j]}|awk -F "/" '{print $2}'|tr -d ' ' `
    echo "serverName---------------->"$serverName
    
    if [ $serverName == "abc-5.0" ] 
    then
    dirstructure=`echo ${URL[$j]} | awk -F"/" 'BEGIN{ OFS="/" } {$1="";$NF=""; print $0 }'`


You don't need awk:

Code:
dirstructure=${URL[$j]#*/}
dirstructure=/${dirstructure%/*}/

Quote:
Code:
    `mkdir -p $distributionName$dirstructure`


Why do you have that in backticks?

And are you sure that $distributionName ends with a slash?
Quote:
Code:
    echo ${URL[j]}
    cp ${URL[j]} $distributionName/$dirstructure


Does $distributionName/$dirstructure exist?
Quote:
Code:
    
    elif [ $serverName == "abcra-5.0" ] 
    then
    dirstructure=`echo ${URL[$j]} | awk -F"/" 'BEGIN{ OFS="/" } {$1="";$NF=""; print $0 }'`
    `mkdir -p $distributionName/$dirstructure`
    
    elif [ $serverName == "abctl-5.0" ]
    then
    dirstructure=`echo ${URL[$j]} | awk -F"/" 'BEGIN{ OFS="/" } {$1="";$NF=""; print $0 }'`
    `mkdir -p $distributionName/$dirstructure`
    elif [ $serverName == "abcbill-5.0" ]
    then
    dirstructure=`echo ${URL[$j]} | awk -F"/" 'BEGIN{ OFS="/" } {$1="";$NF=""; print $0 }'`
    `mkdir -p $ratingdirName/$dirstructure`
    else
    echo "Unknown"
