Public bug reported:
Binary package hint: grep
i wanted to find all 6-letter words starting with 'sho' and ending with
's'. should be simple enough, so i tried:
$ egrep '^sho.{2}s$' /usr/share/dict/words
shoals
shocks
shoe's
shoots
shop's
shores
shorts
shot's
shouts
shoves
then wanting to remove the words with apostrophes from the list, i
tried:
$ egrep '^sho[:alpha:]{2}s$' /usr/share/dict/words
shoals
yikes! what happen to the other words? then out of curiosity i tried a
few more things:
$ egrep '^sho[:lower:]{2}s$' /usr/share/dict/words
shores
using [:lower:] also only matched one word...but a different one. same
for [:upper:] which should have matched none.
$ egrep '^sho[:upper:]{2}s$' /usr/share/dict/words
shores
unless i am using this command wrong (possible, i am no expert here)
this seems like a bug either in code or documentation about how the
command is to work.
