  • Can log into any computers in the lab once you have a login ID
    • Because of this, do not save data in your home directory—save it in a shared folder so other people can access it (who have permission)
• SSH
  • Go the U of R website and look up SSH secure transfer files; then install it onto your computer

  • After signing in, make sure slate is added to your profile
• /P
  • Everything is available to all of HLP!
  • Click on pull down menu on the right side of the SSH screen, then click on /P
  • This is where we keep all of our shared files—one central location
    • E.g. RAs, Poser, materials
  • Materials folder:
    • Headings, Poser files, Mechanical Turk files, etc.

    • Whenever you are adding stimuli, add it to the ReadMe file under Materials

    • Codes
      • cd: change directory

      • h –s: symbolic links
      • chmod: change what can be modified/what can be edited
      • chgrp: changes group
      • ug: user and group
    • Uploading new files
      • Find new file on the left side of SSH (your home directory)
      • Create a new folder under the RAs folder under /p
      • Two little “w”s under the attributes section of each file means you can write in the file
      • One little “w” gives writing privileges to owner only
      • A little “r” gives reading privileges
      • A little “x” gives execution privileges
      • Hit cd to change directories to RAs (where it should be saved)
      • Hit tab button twice to see what is listed under that folder
      • ls –s: gives list of who wrote it, how big the file is, when it was created, and who has the permission to view it
      • ug+rw: gives permission to user and group to read and write on new file
      • -R : changes attributes in every folder/file you own to the new permission privileges
      • * (space before * ) changes privileges for everything
      • One tab button can finish the file notation you are typing out
      • . : stands for home (space before . )
      • .. : goes up just one level (space before .. )
      • chgrp: save your file under another group/folder (if you want to save it under RAs folder, etc.)
      • chown: change ownership of your file
      • Order of notation: command, where you want the file to go to, and where it is now
      • ln –s: gives the file a new name
      • In order to write new file name, you must start from /p/hlp and list every folder until you list the name of the folder you want your file saved under
      • chgmod ug+rwx *: allows everyone to modify what is in the file
    • **Any questions on file notation—ask Katrina or Andrew!
