Escaping parentheses in bash/sed -

this question has answer here:

• is possible escape regex metacharacters reliably sed 2 answers

i've got issues escaping parentheses in string, using bash , sed.

here's i'm doing:

#!/bin/bash  olddescription='(1 phrase/line)' newdescription="\"$volledigenaam\"" (cd /home/hew/git/odoo/addons/$technischenaam ; sed -i s/$olddescription/$newdescription/g __openerp__.py) 

i've read if use single quotes, don't need escape parentheses. tried escaping parentheses backslash didn't work either.

this error:

sed: -e expression #1, char 4: unterminated `s' command

any ideas on how solve this?

scape slash in value of olddescription:

olddescription='(1 phrase\/line)';

then, can try this: sed -i "s/$olddescription/$newdescription/g" __openerp__.py
