bash - split command output into array of lines -


here's bash function command's output parameter , return array of output lines. 

function get_lines {      while read -r line;          echo $line     done <<< $1 }  sessions=`loginctl list-sessions` get_lines "$sessions"

actual output of loginctl list-sessions is:

   session        uid user             seat                     c2       1000 asif             seat0                    c7       1002 sadia            seat0

but while loop runs once printing output in single line. how can array of lines , return it?

you use readarray , avoid get_lines function:

readarray sessions < <(loginctl --no-legend list-sessions)

this create array sessions each line of output of command mapped element of array.

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

Image
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. :)
