str='test1@test2'
echo "${str#*@}"

The symbol #says: Remove the smallest extension prefix matching the pattern.
The symbol %means the removal of the smallest suffix of the extension corresponding to the pattern. (So you can do "${str%@*}"to get the part "test1".)
The symbol /deletes the smallest and first expansion substring corresponding to the following pattern. Bash has it, but it is not POSIX.
