Its right there in the man
page:
pstree shows running processes as a tree. The tree is rooted at either pid or init
if pid is omitted. If a user name is specified, all process trees rooted at pro-
cesses owned by that user are shown.
pstree visually merges identical branches by putting them in square brackets and
prefixing them with the repetition count, e.g.
init-+-getty
|-getty
|-getty
‘-getty
becomes
init---4*[getty]
Child threads of a process are found under the parent process and are shown with
the process name in curly braces, e.g.
icecast2---13*[{icecast2}]
In your case, the process 27108 was started by the script Script.sh
. The Script.sh
created a java
process which spawned another 15 java threads.
A ps -eLf | grep java | wc -l
should returned you a count around the number 15.
man pstree

So, 15
threads of java
process.
