If you get 'lost' or confused in any part of this exercise, don't panic, just use these basic tools to make sure you know where you are on the system (pwd
) and/or change directory back to your home (cd ~
) and start again.
Your session for the exercise with cd
, ls
and pwd
should have gone something like this:
cd ~
/Users/plewis
pwd
u'/Users/plewis'
Now, let's make sure we understand dot .
:
cd .
/Users/plewis
Get a listing (this will be different for different users!):
ls
Desktop/ Dropbox/ Music/ Sites/ stuff/ Documents/ Library/ Pictures/ geogg122/ Downloads/ Movies/ Public/ public_html/
cd ~ucfajlg
/Users/ucfajlg
pwd
u'/Users/ucfajlg'
ls
Desktop/ Downloads/ Movies/ Pictures/ Sites/ Documents/ Library/ Music/ Public/
Or, get a listing without changing directory:
ls ~plewis
Desktop/ Dropbox/ Music/ Sites/ stuff/ Documents/ Library/ Pictures/ geogg122/ Downloads/ Movies/ Public/ public_html/
ls ~ucfajlg
Desktop/ Downloads/ Movies/ Pictures/ Sites/ Documents/ Library/ Music/ Public/
ls ~plewis/Music
iTunes/
cd /Users/plewis
/Users/plewis
pwd
u'/Users/plewis'
cd /Users/ucfajlg
/Users/ucfajlg
Not get a listing of the contents:
ls /Users/plewis
Desktop/ Dropbox/ Music/ Sites/ stuff/ Documents/ Library/ Pictures/ geogg122/ Downloads/ Movies/ Public/ public_html/
ls .
Desktop/ Downloads/ Movies/ Pictures/ Sites/ Documents/ Library/ Music/ Public/
cd ~
/Users/plewis
pwd
u'/Users/plewis'
ls
Desktop/ Dropbox/ Music/ Sites/ stuff/ Documents/ Library/ Pictures/ geogg122/ Downloads/ Movies/ Public/ public_html/
Now we will move relative to this:
cd ../ucfajlg
/Users/ucfajlg
pwd
u'/Users/ucfajlg'
ls
Desktop/ Downloads/ Movies/ Pictures/ Sites/ Documents/ Library/ Music/ Public/
ls ../ucfajlg
Desktop/ Downloads/ Movies/ Pictures/ Sites/ Documents/ Library/ Music/ Public/
cd ../plewis
/Users/plewis
pwd
u'/Users/plewis'
