Each file is displayed at most once.

EXIT STATUS
0 if any name matched any glob
1 if no name matched any glob

use case in to do the glob matching

EXAMPLES

\$ $(basename $0) '*'
123
abc

abc123

EOF
exit 2
} >&2

#execute ls pattern, to check whether we have any file macthes the glob
#$* store all the parameters passed to the shell script
#output of ls command will not be shown in the console

file=""
total=0
pattern=""

for pattern in $*
do
ls $pattern >/dev/null 2>&1
if [ $? == 0 ]
then
total=$((total+1))
#append the file list in variable "file"
file=$file" "$pattern
fi
done

#if total is more than 0, then exit with 0, else, exit 1
if [ $total -ge 1 ]
then
#display the list of files in one in a line
echo $file|tr " " "\n"
#exit with the ret value
exit 0
else
exit 1
fi

Sample Output:

We can use "echo $?" to verify the return/exit value of the script
