Error sed in awk ? or nested awk ?

Hey all,

Can I put sed command inside the awk action ?? If not then can i do grep in the awk action ??

For ex:

awk '$1=="174" { ppid=($2) ; sed -n '/$ppid/p' tempfind.txt ; }' tempfind.txt

Assume: 174 is string.
Assume: tempfind.txt is used for awk and sed both.

tempfind.txt contains :

t2589vg 8888 11234 -ksh
mqsiadm 128 134 -ksh
mqsiadm 174 8888 -ksh



Please let me know, its an urgent.
Thanks to all brains.

You can give your opinion/examples/suggustions regarding the same (to use: sed in awk or grep in awk or nested awk).

NAME
grep - search a file for lines containing a given pattern SYNOPSIS
grep [-elnsv] pattern [file] ... OPTIONS
-e -e pattern is the same as pattern -c Print a count of lines matched -i Ignore case -l Print file names, no lines -n Print line numbers -s Status only, no printed output -v Select lines that do not match EXAMPLES
grep mouse file # Find lines in file containing mouse grep [0-9] file # Print lines containing a digit DESCRIPTION
Grep searches one or more files (by default, stdin) and selects out all the lines that match the pattern. All the regular expressions accepted by ed and mined are allowed. In addition, + can be used instead of * to mean 1 or more occurrences, ? can be used to mean 0 or 1 occurrences, and | can be used between two regular expressions to mean either one of them. Parentheses can be used for grouping. If a match is found, exit status 0 is returned. If no match is found, exit status 1 is returned. If an error is detected, exit status 2 is returned. SEE ALSO
