In a script or a unix shell, you, after executing a command, can use
$! to obtain the PID of the last process and $? to obtain the exit code
of the process. Then you can use this variables to form the name of a
file or to store it on a file to subsecuent use, like killing the
process later. e.g

miguel at laptop:~$ evince &
[1] 13500
miguel at laptop:~$ echo $!
13500
miguel at laptop:~$ echo $?
0
miguel at laptop:~$ echo $! > evince.pid
miguel at laptop:~$ cat evince.pid 
13500
miguel at laptop:~$ man kill
miguel at laptop:~$ kill -9 `cat evince.pid `
miguel at laptop:~$ 

that are backticks around the cat command.
