Ah, it's a tab after the size, not a series of spaces. But even with your
suggestion, it's the same deal:
[eben@pc eben]$ ddu -h /export/media/*
+ du -s /export/media/backgrounds /export/media/ferret-legging.txt
/export/media/images /export/media/midi /export/media/mod
/export/media/movie /export/media/mp3 /export/media/palette.64.gif
/export/media/palette.64.ppm /export/media/patterns
/export/media/root.cache.980907 /export/media/sounds /export/media/temp
+ sort -n
+ sed 's@ \./@ @'
+ eval cut -f 2- -d '"' '"'
++ cut -f 2- -d ' '
4 /export/media/palette.64.gif
4 /export/media/palette.64.ppm
4 /export/media/root.cache.980907
16 /export/media/ferret-legging.txt
442 /export/media/patterns
1413 /export/media/mod
16240 /export/media/midi
31731 /export/media/temp
159625 /export/media/sounds
422843 /export/media/backgrounds
1732338 /export/media/movie
4014387 /export/media/images
5605004 /export/media/mp3
And I made sure that in the script is a tab, not spaces:
vv-----------------space------------------v
0000620 2d 20 2d 64 20 22 09 22 27 0a 23 5c 7c 20 77 68 >- -d "."'.#\| wh<
^^------------------tab---------------^
What I want to see is this:
[eben@pc eben]$ du -s /export/media/* | sort -n | cut -f 2- -d " "
/export/media/palette.64.gif
/export/media/palette.64.ppm
/export/media/root.cache.980907
/export/media/ferret-legging.txt
/export/media/patterns
/export/media/mod
/export/media/midi
/export/media/temp
/export/media/sounds
/export/media/backgrounds
/export/media/movie
/export/media/images
/export/media/mp3
Then I can pipe that sorted list through some stuff to get each element's
size.
::tnme passes::
OK, I have a winner:
TAB=" "
PP='cut -f 2- -d "$TAB"'
...
du -s "$@" \
| sort -$SORT_ARGS \
| sed 's@ \./@ @' \
| eval $PP ;;
Jeez, what a PITA.
