How to get PID of the current process in Shell-script

[sambit]

Hi,

Can anyone help in getting the PID of the current process in Shell. Well I am working on HP-UX 11.00.

The environment variable $ contains the process id of the current shell, while PPID contains its parent process id.
Example:

echo $$ $PPID

Is it what you are looking for ?

TIP It may be good pratice to use the PID number with any temp files created with your shell scripts.
Example1:
tempfile="/tmp/scriptname.tmp.$$"

rm $tempfile

Example2:
tempfile1=="/tmp/scriptname.tmp1.$$"
tempfile2=="/tmp/scriptname.tmp2.$$"

rm /tmp/*.$$
