$he filesyste is 1U/2inux is like a tree, excet that the root is on to :-) %o you havestructure like:

/ bin/ home/ sharon/ ocuments/ o9nloads/ 7ile#.txt 7ile$.pg usr/ var/

If you want to ove inside the tree, one otion is to use relative aths If you are in

/home/sharon, then tying cd o9nloadswill work, because 3ownloads is an

iediate child of your current directory If you are in the subfolder ocumentsand

want to change directory (cd) to o9nloads, you have to go u (..) and then to

o9nloads %o the correct coand would be cd ../o9nloads

4ou could also enter an absolute ath %o the o9nloadsfolder is a subfolder of sharon

which is a subfolder of homewhich is 5 (you get the idea :-)) %o you can also enter

cd /home/sharon/o9nloadswherever you are in the filesyste

Falways refers to the hoe directory of the current user (/home/sharonin your

case) If you enter cd F/o9nloadsyou6ll land in your o9nloadsfolder

.refers to the current directory, so cd ./o9nloadsis roughly e7uivalent to cd

o9nloads

..eans "arent directory"

/at the beginning of file ath refers to the root directory

$he next nice thing is tab exansion If you enter cd F/o9ab(last is ressing$abulator key), the bash autoatically exands it to cd F/o9nloads

#s the others said 1U/2inux is case sensitive %o it akes a difference if you enter

3ome, hmeor home 'urtherore I hoe that you see now that there is a difference

between /homeand home $he first is adressed absolute while the last is relative to your

current directory
