Can someone please explain to me why this isn't doing what I expect
(i.e. removing the named directories in the current directory), and
perhaps suggest a solution...

| cut -b 56-`; do rmdir $item;

Quote:> done

rmdir: Boy Blue - Electric Light Orchestra
Can't Get It Out Of My Head - Electric Light Orchestra
Dark City (Demo) - Electric Light Orchestra
Eldorado
Eldorado - Electric Light Orchestra
Eldorado Finale - Electric Light Orchestra
Eldorado Instrumental Medley - Electric Light Orchestra
Eldorado Overture - Electric Light Orchestra
Eldorado Remastered.nfo
Illusions in G Major - Electric Light Orchestra
Laredo Tornado - Electric Light Orchestra
Mister Kingdom - Electric Light Orchestra
Nobody's Child - Electric Light Orchestra
Poor Boy (The Greenwood) - Electric Light Orchestra: File name too long

How do I get the files in a directory to list singly?

Thanks...

I think resetting IFS is giving you a problem. If all you want to do
is remove the directories, try something like this.

for f in *;do [ -d "$f" ] && rmdir "$f";done

If you put double quotes around $f, you don't have to reset IFS.

It seems obvious, you need a newline in IFS. The default value
for IFS is <space><tab><newline>.
IFS=\
;for item in `ls -Al | grep -E '^d' | cut -b 56-`; do rmdir $item;
done
'$' means end of line in regular expressions, but 'IFS=$' sets the field
separator to a literal dollar sign.
