A short but proper description the entire situation (how the script is called, what the positional parameters stand for, how parfile and test_10062019.par relate) would help people understand the problem and help you get faster and better answers. Meaningful indentation would improve readability and understandibility of your code.

Use the correct mechanism to convey a shell variable's contents into an awkscript, like

Code:

awk -vPWD=$vpd '/appdbinstall/ {$0=$0;for (i=1;i<NF;i++)t=t ;$0=$0 "/" PWD}1' file

You might want to try sth. like this on your way to optimize your script:

Code:

awk '
NR == 1         {PWD = $0
                 next
                }
/appdbinstall/  {$NF = $NF "/" PWD
                 CHD = 1
                }
1
END             {if (CHD) print "appdinstall exists." > "/dev/stderr"
                 exit (!CHD)
                }
'  encrypted.pwd test_10062019.par

Check for the exit code to control further processing.
