    Hi Alessandro,

    What command use?

    sac> cd new_dir

    should to do the trick if you use sac version 101.6a
    if you want use other command of the operating system,
    you need use:
    sac> sc command
    where sc stand by System Command

    But, also check the permission of directory...

    My Dirs in general have permissions:
    drwxr-xr-x

    HTH,

    M.

      Hi,
      thank you for your fast response.

      When i enter in a folder i use a command : cd 'name_folder'.
      In most cases i can enter without problems, instead in some cases the
      programm send me an error message (error 124).
      If i quit and restart sac the error disappear.
      It is a bug ?

      Thank you very much.
      Best regard,

      Alessandro.

        Dear All -

        Using the system’s ‘cd’ command inside SAC is not wise because its behavior is ambiguous and unpredictable. If you want that command to change the default file search directory for SAC commands, it probably will not work. SAC runs any system command in a sub-shell, and, by design in Unix, generic sub-shells do not affect the settings in their parent shells. So it should not, and probably does not affect SAC’s file search path.

        SAC could try to be helpful and parse the “cd” command itself, but this won’t work in many cases, for example when you have aliased the “cd” command in your shell to do something else in addition to changing directory. Hence, you should not rely on it working reliably, if at all.
