string - sed - search and replace between 2 marks -

i want search string , modify it

i build string that:

|bor.team1-fcteam2| 

but also:

|fcteam2-bor.team1| 

or pattern

|text–text| 

i want change name of team1, can have different names eg:

bor.team1 b.team1 bteam091 ... 

i want everytime same name -> b.team1

team everytime in different diction!

i play arround sed 's/\bbor.team1\b/b.team1/g', must find , know every different diction.

that shoudl need:

echo $string | sed -e 's/[a-za-z\.]\+team\([0-9]\+\)/b.team\1/g' 

it searches alphabetic characters , dot (.) followed word team, followed number ([0-9]). replaced whatever want. in example it's b.team followed found number (\1).
