Let's look at just three commands in this script:
The first command in this list sets the variable PID to the exit status of the previous command (echo "$line") which is almost always going to be 0. The second command causes the script to wait for about 2 seconds. Then the third command (after parameter expansion) is:
This is a request to terminate all processes in the current process group. On most systems, killing all processes in the current process group includes killing the shell that is running this script.
I hope someone can shed any light on this mystery.

killall
KILLALL(1) User Commands KILLALL(1)NAME
killall - kill processes by name
SYNOPSIS
killall [-Z, --context pattern] [-e, --exact] [-g, --process-group] [-i, --interactive] [-n, --ns PID] [-o, --older-than TIME]
[-q, --quiet] [-r, --regexp] [-s, --signal SIGNAL, -SIGNAL] [-u, --user user] [-v, --verbose] [-w, --wait] [-y, --younger-than TIME]
[-I, --ignore-case] [-V, --version] [--] name ...
killall -l
killall -V, --version
DESCRIPTION
killall sends a signal to all processes running any of the specified commands. If no signal name is specified, SIGTERM is sent.
Signals can be specified either by name (e.g. -HUP or -SIGHUP) or by number (e.g. -1) or by option -s.
If the command name is not regular expression (option -r) and contains a slash (/), processes executing that particular file will be
selected for killing, independent of their name.
killall returns a zero return code if at least one process has been killed for each listed command, or no commands were listed and at least
one process matched the -u and -Z search criteria. killall returns non-zero otherwise.
A killall process never kills itself (but may kill other killall processes).
OPTIONS -e, --exact
Require an exact match for very long names. If a command name is longer than 15 characters, the full name may be unavailable (i.e.
it is swapped out). In this case, killall will kill everything that matches within the first 15 characters. With -e, such entries
are skipped. killall prints a message for each skipped entry if -v is specified in addition to -e,
-I, --ignore-case
Do case insensitive process name match.
-g, --process-group
Kill the process group to which the process belongs. The kill signal is only sent once per group, even if multiple processes
belonging to the same process group were found.
-i, --interactive
Interactively ask for confirmation before killing.
-l, --list
List all known signal names.
-n, --ns
Match against the PID namespace of the given PID. Use 0 to match against all namespaces. The default is to match against the current
PID namespace.
-o, --older-than
Match only processes that are older (started before) the time specified. The time is specified as a float then a unit. The units
are s,m,h,d,w,M,y for seconds, minutes, hours, days, weeks, Months and years respectively.
-q, --quiet
Do not complain if no processes were killed.
-r, --regexp
Interpret process name pattern as a POSIX extended regular expression, per regex(3).
-s, --signal, -SIGNAL
Send this signal instead of SIGTERM.
-u, --user
Kill only processes the specified user owns. Command names are optional.
-v, --verbose
Report if the signal was successfully sent.
-V, --version
Display version information.
-w, --wait
Wait for all killed processes to die. killall checks once per second if any of the killed processes still exist and only returns if
none are left. Note that killall may wait forever if the signal was ignored, had no effect, or if the process stays in zombie
state.
-y, --younger-than
Match only processes that are younger (started after) the time specified. The time is specified as a float then a unit. The units
are s,m,h,d,w,M,y for seconds, minutes, hours, days, weeks, Months and years respectively.
-Z, --context
(SELinux Only) Specify security context: kill only processes having security context that match with given extended regular expres-
sion pattern. Must precede other arguments on the command line. Command names are optional.
FILES
/proc location of the proc file system
KNOWN BUGS
Killing by file only works for executables that are kept open during execution, i.e. impure executables can't be killed this way.
Be warned that typing killall name may not have the desired effect on non-Linux systems, especially when done by a privileged user.
killall -w doesn't detect if a process disappears and is replaced by a new process with the same PID between scans.
If processes change their name, killall may not be able to match them correctly.
killall has a limit of names that can be specified on the command line. This figure is the size of an unsigned long multiplied by 8. For
most 32 bit systems the limit is 32 and similarly for a 64 bit system the limit is usually 64.
