comment id command doesn't show all user's groups
The /etc/group file is the default way group information is stored. Systems can supplement it with other sources such as YP/NIS and LDAP. The id and getent commands will query whatever source(s) the system uses. (Likewise for /etc/passwd and several other databases).

comment What does the period indicate when an environmental variable is set like “VARIABLE_NAME=.”
@godlygeek: The root directory does have a .. entry. Another way to look at it is that every directory has a .. entry pointing to its parent -- and the root directory / is its own parent.

comment How to tell “cat” command to not hang on when there is no path provided?
cat "" doesn't hang, but it does print an error message: cat: : No such file or directory (referring to the empty string). It's better to test whether $1 exists, probably by checking the value of $#.

I think I have a better solution that doesn't require using crontab. I'll update this answer (and delete this comment) once I've verified that it actually works.

comment Does `sl` ever show the current directory?
You could always create the intermediate directories -- but then it wouldn't be showing (just) the contents of the current directory.

comment wget - corrupted directories
The command name is wget, and Unix command names are case-sensitive. I've seen documentation refer to it as Wget, but I've never seen it referred to as wGet.

At least you didn't chmod -x the directories!
