Question 4

[Nadav1234]

Everything I've tried to do failed.
ls -d /wildcards/[a-z]*

The problem is the first / - You're referring to a directory named /wildcards while you probably mean to refer to /home/nadav/lab/wildcards (or something like that).

All user data (which is the files/directories you create) is saved in a special directory called your home directory.

1. To see the full path to your home directory type echo $HOME.

2. When you're inside $HOME/lab you should use a relative path to access a subfolder (such as wildcards) - i.e. should write ls -d wildcards/[a-z]*.

3. Or if you're already INSIDE wildcards you'd type ls -d [a-z]*

4. BTW to know where you are you can type pwd

Let me know if it now works or have any further questions

Ah yes an interesting Ubuntu feature. You can read more about it here:
http://teaching.idallen.org/net2003/06w/notes/character_sets.txt

Basically Ubuntu (and other recent linuxes) use a sort order that mixes lower and upper case letters: AaBbCcDd... etc.

That's why your [a-z] doesn't seem to work: It actually does work but when your linux sees the a-z it translates it to aBbCcDd...Zz

You can change the collation order by running the command: export LC_ALL=POSIX (no spaces around the = sign). In future lessons we'll learn more about the export syntax and how it works.
