Suppose a full path like dir1/dir2/dir3/mydir is supplied during the execution of a shell script where dir1,dir2,dir3 and mydir are directory names. Write a shell script, which creates these directories if they do not exist and change to the last directory in the list. Also check for the possibility that there might exist a file with the same name as any of the directory names present in the supplied path.

Code for Shell script to check dir directory if it exists then change the path, if not then create dir with that name and also check for file name not exists in Unix / Linux / Ubuntu

echo "Enter dir path : "
read path
set `echo $path | tr '/'' '`

for dir in $*
doif [ -d $dir ]
    then
        echo "Direcoty present"
        cd $dir
    elif [ -f $dir ]
    then
        echo "Their is file"
        exit 1    
    else
        echo "Not present dir so Create dir"
        mkdir $dir
        cd $dir
    fi    
done
