Try using this -  mkdir -p dir    NOTE - This will also create any intermediate directories that don t exist  for instance   Check out mkdir -p  or try this -  if      -e  dir     then     mkdir  dir elif      -d  dir     then     echo   Message  1 gt  amp 2 fi

Use mkdir s -p option  but note that it has another effect as well    -p      Create intermediate directories as required   If this option is not specified  the full path prefix of each oper-          and must already exist   On the other hand  with this option specified  no error will be reported if a directory          given as an operand already exists   Intermediate directories are created with permission bits of rwxrwxrwx           0777  as modified by the current umask  plus write and search permission for the owner

if     -d directory    then   mkdir directory fi   or   mkdir -p directory   -p ensures creation if directory does not exist
