Error Parent child Relation !! using awk/sed ???

tempfind.txt file has:
t2589vg 888898 336008 09:15:55 -ksh
mqsiadm 1421774 888898 09:16:48 -ksh

I am searching using 1421774 in the above file tempfind.txt and and trying to get the no. i.e. 888898 [in Blue]. Based on this no. i have to get the first line, where the same no. is there [in Red]. The nos. in Blue has to match with the no. in Red.

That is the process "-ksh" with user id t2589vg that is parent process to "-ksh" of user mqsiadm. And I am trying to get the name of the parent process through its child process id.

How can I do this using awk/sed ???

Please let me know , asap.

let - shell built-in function to evaluate one or more arithmetic expressions SYNOPSIS
ksh let arg... ksh93 let [expr...] DESCRIPTION
ksh Each arg is a separate arithmetic expression to be evaluated. ksh93 let evaluates each expr in the current shell environment as an arithmetic expression using ANSI C syntax. Variables names are shell vari- ables and they are recursively evaluated as arithmetic expressions to get numerical values. let has been made obsolete by the ((...)) syn- tax of ksh93(1) which does not require quoting of the operators to pass them as command arguments. EXIT STATUS
ksh ksh returns the following exit values: 0 The value of the last expression is non-zero. 1 The value of the last expression is zero. ksh93 ksh93 returns the following exit values: 0 The last expr evaluates to a non-zero value. >0 The last expr evaluates to 0 or an error occurred. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ SEE ALSO
