I use the following command, but it deletes the term identified then adds the word.

It is very simple to remove a hyphen from a word anywhere in that word using a simple sed command (sed -i 's/-//g' filename), but I am not able to figure out how to do this:
For example,
apple
-orange
tree
pipe-
banana-shake
dupe-
What my output should look like:
apple

I've been looking through the forums for awhile now and looking at the man page for grep and egrep and not seeming to find this scenario so it might not be possible but figured I'd throw it out to get some ideas.

regexp::common::list5.18
Regexp::Common::list(3) User Contributed Perl Documentation Regexp::Common::list(3)NAME
Regexp::Common::list -- provide regexes for lists
SYNOPSIS
use Regexp::Common qw /list/;
while (<>) {
/$RE{list}{-pat => 'w+'}/ and print "List of words";
/$RE{list}{-pat => $RE{num}{real}}/ and print "List of numbers";
}
DESCRIPTION
Please consult the manual of Regexp::Common for a general description of the works of this interface.
Do not use this module directly, but load it via Regexp::Common.
$RE{list}{-pat}{-sep}{-lastsep}
Returns a pattern matching a list of (at least two) substrings.
If "-pat=P" is specified, it defines the pattern for each substring in the list. By default, P is "qr/.*?S/". In Regexp::Common 0.02 or
earlier, the default pattern was "qr/.*?/". But that will match a single space, causing unintended parsing of "a, b, and c" as a list of
four elements instead of 3 (with "-word" being "(?:and)"). One consequence is that a list of the form "a,,b" will no longer be parsed. Use
the pattern "qr /.*?/" to be able to parse this, but see the previous remark.
If "-sep=P" is specified, it defines the pattern P to be used as a separator between each pair of substrings in the list, except the final
two. By default P is "qr/s*,s*/".
If "-lastsep=P" is specified, it defines the pattern P to be used as a separator between the final two substrings in the list. By default
P is the same as the pattern specified by the "-sep" flag.
For example:
$RE{list}{-pat=>'w+'} # match a list of word chars
$RE{list}{-pat=>$RE{num}{real}} # match a list of numbers
$RE{list}{-sep=>" "} # match a tab-separated list
$RE{list}{-lastsep=>',s+ands+'} # match a proper English list
Under "-keep":
$1 captures the entire list
$2 captures the last separator
$RE{list}{conj}{-word=PATTERN}
An alias for $RE{list}{-lastsep=>'s*,?s*PATTERNs*'}
If "-word" is not specified, the default pattern is "qr/and|or/".
For example:
$RE{list}{conj}{-word=>'et'} # match Jean, Paul, et Satre
$RE{list}{conj}{-word=>'oder'} # match Bonn, Koln oder Hamburg
$RE{list}{and}
An alias for $RE{list}{conj}{-word=>'and'}
$RE{list}{or}
An alias for $RE{list}{conj}{-word=>'or'}
