bash - Send command to open process in Shell file -


in bash how can issue command running process started?

for example;

# start bluez gatttool connect bluetooth device  gatttool -b $mac -i connect # send 'connect' gatttool process?

currently shell script doesn't connect line because gatttool process running.

if want send string "connect\n" process, can use standard pipe:

echo "connect" | gatttool -b $mac -i

if want engage in more complex "conversation" gatttool process, take @ expect (1) , chat (8) tool, allow send sequence of strings, , wait responses.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
