Full Discussion: Lookup in another file and conditionally modify it inline

Assuming that your first sample file is named f1 rather than f1 being the first line of your first file and that your second input file is named f2 rather than the first line of your second input file being f2 (tran number is second field), then you can use whichever one of the suggestions RudiC provided that matches the actual input you need to process. If those two lines are actually in your input files, the following seems to produce the output you want:
Code:
awk '
BEGIN {	FS = OFS = ","
}
FNR == 1 {
	next
}
FNR == NR {
	tn[$1]
	next
}
$2 in tn {
	if($5 == "X")
		$2 = $2 "_P"
	else if($5 == "Y")
		$2 = $2 "_T"
}
1' f1 f2

If you want to try this (or either of RudiC's suggestions) on a Solaris/SunOS operating system, change awk to /usr/xpg4/bin/awk or nawk.

ucblinks

ucblinks(1B)					     SunOS/BSD Compatibility Package Commands					      ucblinks(1B)

NAME

       ucblinks - adds /dev entries to give SunOS 4.x compatible names to SunOS 5.x devices

SYNOPSIS

       /usr/ucb/ucblinks [-e rulebase] [-r rootdir]

DESCRIPTION

       ucblinks  creates symbolic links under the /dev directory for devices whose SunOS 5.x names differ from their SunOS 4.x names. Where possi-
       ble, these symbolic links point to the device's SunOS 5.x name rather than to the actual /devices entry.

       ucblinks does not remove unneeded compatibility links; these must be removed by hand.

       ucblinks should be called each time the system is reconfiguration-booted, after any new SunOS 5.x links that are needed have been  created,
       since the reconfiguration may have resulted in more compatibility names being needed.

       In  releases prior to SunOS 5.4, ucblinks used a  nawk rule-base to construct the SunOS 4.x compatible names. ucblinks no longer uses  nawk
       for the default operation, although  nawk rule-bases can still be specifed with the -e option.  The  nawk rule-base equivalent to the SunOS
       5.4 default operation can be found in /usr/ucblib/ucblinks.awk.

OPTIONS

       -e rulebase     Specify rulebase as the file containing nawk(1) pattern-action statements.

       -r rootdir      Specify rootdir as the directory under which dev and devices will be found, rather than the standard root directory /.

FILES

       /usr/ucblib/ucblinks.awk        sample rule-base for compatibility links
