The first thing is a general observation: when you write some "if..else..fi" and you end up with commands in both the "if"- and the "else"-branches - they could be placed outside the "if" too, no?
No, I didn't know that. Do you mean, "in the then and else branches"? Although I've read that fi is simply if backwards, I've always read it as finish. You know, like, it's the end. I'm still not entirely clear on how these commands, or arguments, or whatever they're called, work.
But you're saying that I could could just put a single instance of find, or whatever command, after fi, and it'll execute no matter what happens above it? Yeah, ok, I can see that now.

I should also mention that I simply forgot to delete ls ~/$dir, which I intended to do. I like the output of find better, because prints only the path on one line, as opposed to what I was getting, or hoping to get, from ls.

The next thing is a minor detail...
No, you're right, especially if we try to make something that might actually be useful. I'm thinking it's possible in many cases that a variable could be handed some white spaces. Do you think it's a good idea to always quote variables, as a matter of course?

Quote:
Next detail: "mkdir" intrinsics.
Right! Again, something I hadn't considered. I tried it, and as you suggest, it did not work. Adding the -p flag fixes it.

Quote:
Last thing: "find" is not necessary in this case.
While I did not try this - at least, not yet - I wonder if cd .. would always work, since it only takes you up one level? For instance, if you had empty directory /Fun, then specified, say, a new directory four levels down: /Fun/X1/X2/X3 Wouldn't cd .. only position you, (and ls), at /X2?

mkfontdir

MKFONTDIR(1)						      General Commands Manual						      MKFONTDIR(1)

NAME

       mkfontdir, fonts.dir, fonts.scale, fonts.alias - create an index of X font files in a directory

SYNOPSIS

       mkfontdir [directory-name ... ]

DESCRIPTION

       For  each  directory  argument,	mkfontdir  reads all of the font files in the directory searching for properties named "FONT", or (failing
       that) the name of the file stripped of its suffix.  These are converted to lower case and used as font names, and, along with the  name	of
       the font file, are written out to the file "fonts.dir" in the directory.  The X server and font server use "fonts.dir" to find font files.

       The  kinds  of  font  files  read  by  mkfontdir depend on configuration parameters, but typically include PCF (suffix ".pcf"), SNF (suffix
       ".snf") and BDF (suffix ".bdf").  If a font exists in multiple formats, mkfontdir will first choose PCF, then SNF and finally BDF.

       The first line of fonts.dir gives the number of fonts in the file.  The remaining lines list the fonts themselves, one  per  line,  in  two
       fields.	First is the name of the font file, followed by a space and the name of the font.

SCALABLE FONTS

       Because	scalable  font	files do not usually include the X font name, the file "fonts.scale" can be used to name the scalable fonts in the
       directory.  The fonts listed in it are copied to fonts.dir by mkfontdir.  "fonts.scale" has the same format as the "fonts.dir" file.

FONT NAME ALIASES

       The file "fonts.alias", which can be put in any directory of the font-path, is used to map new names  to  existing  fonts,  and	should	be
       edited  by  hand.   The	format is two white-space separated columns, the first containing aliases and the second containing font-name pat-
       terns.  Lines beginning with "!" are comment lines and are ignored.

       If neither the alias nor the value specifies the size fields of the font name, this is a scalable alias.  A font  name  of  any	size  that
       matches this alias will be mapped to the same size of the font that the alias resolves to.

       When  a font alias is used, the name it references is searched for in the normal manner, looking through each font directory in turn.  This
       means that the aliases need not mention fonts in the same directory as the alias file.

       To embed white space in either name, simply enclose it in double-quote marks; to embed double-quote marks (or any other character), precede
       them with back-slash:

       "magic-alias with spaces"     ""font name" with quotes"
       regular-alias		fixed

       If  the	string	"FILE_NAMES_ALIASES"  stands  alone on a line, each file-name in the directory (stripped of its suffix) will be used as an
       alias for that font.

FILES

       fonts.dir      List of fonts in the directory and the files they are stored in.	Created by mkfontdir.  Read  by  the  X  server  and  font
		      server each time the font path is set (see xset(1)).

       fonts.scale    List of scalable fonts in the directory.	Contents are copied to fonts.dir by mkfontdir.

       fonts.alias    List of font name aliases.  Read by the X server and font server each time the font path is set (see xset(1)).

SEE ALSO

       X(1), Xserver(1), xfs(1), xset(1)
