Write a shell script, which will receive any number of filenames as arguments .The shell script should check whether such files already exist. If they do, then it should be reported. If these files do not exist then check if a subdirectory called mydir exists in the current directory .If it doesn't exist then itshould be created and in it files supplied as arguments should get created .If mydir already exists then it should be reported along with the number of files that are currently present in myir.

for i in $*
doif [ -f $i ]
        then
                echo "File $i is already exist."elseif [ -d mydir ]
                then
                        cnt=0
                        cd mydir
                        for j in `ls`
