You don't need sed. bash is enough and fast

for fl in $(ls *spkg);do
echo ${fl%%-*}
done

no need for the error prone ls subshell.
'%%-*' removes all hyphens. that would trim boost-cropped-1.34.1.spkg
too far.

cd /whatever/dir
for x in *; do printf "%s\n" "${x%-*}"; done

there's one downside i know of - if the directory does not contain any
files, the globbing pattern is shown (afaik sh, bash, ksh, more?):

cd /tmp/t/
# for x in *; do printf "%s\n" "$x"; done
*
#

one might 'test -[e|f]' to work around, but that slows down the whole thing.

best regards

I should have said, 'not any matching files'...

also to mention that it'll also list directories...
