Disregarding the adjacent colons (which don't matter anyway), reasonably
recent bashes can make the substitution:
:~ $ jh=x:y:z
:~ $ p=a:b:c
:~ $ p=${p//$jh}
:~ $ echo $p
a:b:c
:~ $ p=a:b:x:y:z:c
:~ $ p=${p//$jh}
:~ $ echo $p
a:b::c
And if you do want to eliminate the adjacent colons:
:~ $ p=${p//::/:}
:~ $ echo $p
a:b:c
Or if you really want to go wild:
:~ $ shopt -s extglob
:~ $ p=a:b:x:y:z:c
:~ $ echo ${p//?(:)$jh?(:)/:}
a:b:c
:~ $ p=a:b:c
:~ $ echo ${p//?(:)$jh?(:)/:}
a:b:c
(always trying to stay in-shell where possible.)
