Deleting parentheses in shell script

I would like to create mechanism to delete parentheses, or parentheses and the text between them. For example:

before:

text0 text1 text2 (text3 text4)

after:

text0 text1 text2 text3 text4

or:

text0 text1 text2

I would like to test both options and other type of brackets but I'm not sure what tool should I use, Awk or Sed or maybe something else? I would be grateful for any advice.

Can brackets be nested?

Good question. Let's say yes but only brackets that are deeply nested - file may be json and curly braces will be preseted in every case.

The other half of your question,
deleting just the parentheses (but not the text between them):

echo 'text0 text1 text2 (text3 text4)' |
 sed 's/[()]//g'

Output:

text0 text1 text2 text3 text4

To keep the text, this is enough:

tr -d '()'

To delete the text and parentheses:

sed 's/([^)]*)//g;s/ / /g'

If the text contains nested parenthesis like :

echo 'text0 (text1 (textA )) text2 (text3 text4) test5' |
 sed -e :A -e 's/([^()]*)//;tA' -e 's/ / /g'

sed 's/([^)]*)//g;s/ / /g'
