The exit code used to provide a simple reply to the calling script or process as to the result of executiing the script. Code zero means it worked. Other codes are chosen by the script writer.
A calling script will find that the value of the exit code is in the Environment Variable $?
So would it be better practice to end my script with exit 0 instead of just exit?

The awk looks for any white space between fields and outputs the first field ($1).
So the $1 in the first part of that line of code ls -log "$1" is referring to the parameter of the script (in this case, a directory name), but the $1 in the second part of that line of code awk '{print $1}' is referring to the first field (in this case, the permissions), right?

Sorry, I don't understand this command.
By using f_count=$(grep -c "-........." $TF), I was trying to say count the number of lines that start with a - (which would signify a file, as opposed to a d, for directory, of course) and are followed by any variation of rwx permissions (this is why I tried using the "dot" wildcard . nine times). Should I have instead written f_count=$(grep -c "-.*" $TF)? My thinking is still probably wrong...

Quote:
f_count=$(grep -c \^\- $TF)
Could you please explain what the \^\- does?

mfontset_lookup

mfontset_lookup(3m17n)						 The m17n Library					    mfontset_lookup(3m17n)

NAME

       mfontset_lookup - Lookup a fontset.

SYNOPSIS

       MPlist * mfontset_lookup (MFontset * fontset, MSymbol script, MSymbol language, MSymbol charset)

DESCRIPTION

       Lookup a fontset. The mfontset_lookup() function lookups fontset and returns a plist that describes the contents of fontset corresponding
       to the specified script, language, and charset.

       If script is Mt, keys of the returned plist are script name symbols for which some fonts are specified and values are NULL.

       If script is a script name symbol, the returned plist is decided by language.

       o If language is Mt, keys of the plist are language name symbols for which some fonts are specified and values are NULL. A key may be Mt
	 which means some fallback fonts are specified for the script.
       o If language is a language name symbol, the plist is a FONT-GROUP for the specified script and language.  FONT-GROUP is a plist whose keys
	 are FLT (FontLayoutTable) name symbols (Mt if no FLT is associated with the font) and values are pointers to MFont.
       o If language is Mnil, the plist is fallback FONT-GROUP for the script.
       If script is Mnil, the returned plist is decided as below.
       o If charset is Mt, keys of the returned plist are charset name symbols for which some fonts are specified and values are NULL.
       o If charset is a charset name symbol, the plist is a FONT-GROUP for the charset.
       o If charset is Mnil, the plist is a fallback FONT-GROUP.
RETURN VALUE

	   It returns a plist describing the contents of a fontset. The plist should be freed by m17n_object_unref().
