Yes, you take the whole line.

Don't write this! You can change Terminal's behaviour in how it shows 
'codes' as 'glyphs.' And Terminal itself can't display a file name. 
It's either ls or the shell's completion mechanism. You can make ls 
work right by make it an alias to 'ls -w'.

Supposed your TeX source is always the most recent file in the 
directory, you can detect this with 'ls -w1t'. With head you catch the 
first name, with iconv you convert the UTF-8 name into ISO Latin:

	ls -1tw | head -1 | iconv -f UTF-8-MAC -t ISO-8859-15

You too can put the iconv part after or before awk:

	\immediate\write18{pwd | iconv -f UTF-8-MAC -t ISO-8859-15 | awk 
-F'\\n' '{print "\\newcommand{\\path}{" $1 "\\xspace}"}' > 

	\immediate\write18{pwd | awk -F'\\n' '{print "\\newcommand{\\path}{" 
$1 "\\xspace}"}'  | iconv -f UTF-8-MAC -t ISO-8859-15 > tmpdatei.tex}

I think the first form is more promissing, since you reduce two or 
three bytes of an UTF-8 representation to only one. And I think the 
right one! Be sure to set TeX's input encoding to that of iconv's 
output encoding! iconv's knowledge of encodings is listed with 'iconv
