* Since $@ parameter may have pipe '|' it should be processed correctly.
Currenly the part before pipe is assigned as $@ so bash runs pipe with
commands after it after execution of function. However, we want to assign
command with pipe to $@ thus "" around command with pipe are required.
* replace $() with eval as $() doesn't work correctly with pipe as it tries to
escape pipe so output variable contains wrong data.
* This patch adds tonumber to first invocation
