Good morning
I have this variable
NODES="lep1mk17 lep1mk18 lep1mk19"
And I am executing this loop (I want to work with parallel processes)
56 for i in $NODES
57 do
58 java -jar jmxterm-1.0.1-uber.jar --url <url:port> -i $LOGDIR/$i > $LOGDIR/$i.out &
59 pid-$i=$!
60 done
In this case I will have 3 processes in background.
To know when they finish, I use the variable pid-$i
At this point I want to stop my script until the background processes ending, so I do:
62 for i in $NODES
63 do
64 wait $(pid-$i)
65 done
When I execute the script I got some errors:
./countMessagesTopicV4.sh: line 59: pid-lep1mk17=30491: command not found
./countMessagesTopicV4.sh: line 59: pid-lep1mk18=30493: command not found
./countMessagesTopicV4.sh: line 59: pid-lep1mk19=30495: command not found
./countMessagesTopicV4.sh: line 64: pid-lep1mk17: command not found
./countMessagesTopicV4.sh: line 64: pid-lep1mk18: command not found
./countMessagesTopicV4.sh: line 64: pid-lep1mk19: command not found

Can someone help me to find my error ?
Variable names have to be literal, you can't just use an expression as a variable name like you're doing. (Also variable names can't have - in them, but that's a second problem)
bash has associative array variables: you want
59: pid[$i]=$!
...
64: wait ${pid[$i]}
