it works fine.. but actually i am passing 2 parameter to the function CHECK_NO_FILES

1. the array
2. the path location where the files needs to be searched..
check out the last line in the below code..

Code:
CHECK_NO_FILES()
{
        FARRAY=$1
        LOCATION=$2

        FARRAY=($@)  # FARRAY contains s1.txt,s2.txt and the LOCATION value too.

        i=0
        for file_name in "${FARRAY[@]}"; do
                
                echo "file_name = {$file_name}"
                NO_FILES[$i]=`ls -1 $LOCATION/$file_name | wc -l`
                echo "NO_FILES[$i] = ${NO_FILES[$i]}"
                i=`expr $i + 1`

        done
}

S_FILES="s1.txt s2.txt"      # a simple variable.
SAP_ARRAY=($S_FILES)     # this line assign each space delimited element to the array.
echo "SAP_ARRAY[0] = $SAP_ARRAY[0]"   # prints SAP_ARRAY[0] = s1.txt
echo "SAP_ARRAY[1] = $SAP_ARRAY[1]"   # prints SAP_ARRAY[1] = s2.txt

CHECK_NO_FILES "${SAP_ARRAY[*]}" "/app/etc"


now when i use
Code:
FARRAY=($@)

and parse the FARRAY, it contains
Code:
FARRAY[0]=s1.txt
FARRAY[1]=s2.txt
FARRAY[2]=/app/etc

i dnt want the last "/app/etc" as an element in the array "FARRAY".
