Top Forums Shell Programming and Scripting Lookup in another file and conditionally modify it inline Post 302989591 by Don Cragun on Monday 16th of January 2017 03:59:51 AM

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.

NAME
yum - Yellowdog Updater Modified shell SYNOPSIS
yum shell [filename] DESCRIPTION
yum includes an interactive shell for conducting multiple commands or sets of commands during a single execution of yum. These commands can be issued manually or passed to yum from a file. The commands are much the same as the normal yum command line options. See here yum(8) for that information. There are a few additional commands documented below. config [argument] [value] args: debuglevel, errorlevel, obsoletes, gpgcheck, assumeyes, exclude If no value is given it prints the current value. If value is given it sets that value. repo [argument] [option] list: lists repositories and their status enable: enable repositories. option = repository id disable: disable repositories. option = repository id transaction [argument] list: lists the contents of the transaction reset: reset (zero-out) the transaction solve: run the dependency solver on the transaction run: run the transaction Examples The following are examples of using the yum shell. list available packagename* groupinfo 'Some Group' install foo remove bar update baz run That will list available packages matching the glob 'packagename*'. It will return information on the group 'Some Group' It will then queue the following commands into the transaction: install foo, remove bar, update baz. Then the 'run' command will resolve dependencies for the transaction commands and run the transaction. SEE ALSO
yum (8) http://yum.baseurl.org/ AUTHORS
See the Authors file included with this program. BUGS
There of course aren't any bugs, but if you find any, they should be sent to the mailing list: yum@lists.baseurl.org or filed in bugzilla. Seth Vidal yum(8)
