I want to use the bash syntax ${var/pattern1/pattern2} to replace the content of $var but for all matching patterns pattern1 instead of the first one.

A=aa 
echo ${A/a/b}
ba

I want to find bb instead of ba.

You can try this syntax which gives output:

A=aa 
echo ${A//a/b}
bb

${A//a/b} replaces all the matches of a with b. Whereas, ${A/a/b} will replace only 1st match of a.
