Top Forums Shell Programming and Scripting Comparing two columns in two files and printing a third based on a match Post 303023520 by dis0wned on Tuesday 18th of September 2018 02:03:57 PM

Nope. Ultimately I am trying to print file1 to a new file with an additional column (VLAN Name), and the matching vlans have the name field appended to the end of the row. If a match is not made, then NA or a blank space is fine. This awk command appended the "vlan name" to the first line but did not return any of the fields


Code:
$ awk -F, 'FNR==NR{if (FNR==1){h=$0}f2[$1]=$2;next} FNR==1{print h, "VLAN Name";next} $5 in f2 {print $0,f2[$5]}' OFS=, file2 file1
VLAN,Name,Status,Ports,Device,VLAN Name

VLAN(7) 						 Miscellaneous Information Manual						   VLAN(7)

NAME
VLAN - virtual local area network DESCRIPTION
This manpage provides a brief overview of VLAN (virtual LAN) technology. VLANs are logical, or network segments that can span multiple physical network segments. A primary benefit of VLANs is that they can iso- late broadcast and multicast traffic by determining which destinations should receive that traffic, thereby making better use of switch and end-station resources. Logical separation using VLAN allows for the logical grouping of PCs, servers and other network resources to behave as if they were con- nected to the same, physical segment, even if they are not. HP-UX VLAN is an implementation of IEEE 802.1p/Q standards. VLAN interfaces can be configured in HP-UX servers using the command (see nwmgr_vlan(1M)) or (see lanadmin_vlan(1M)). HP recommends that you use for HP-UX Release 11i Version 3 and forward. Interfaces can also be configured using the web-based management tool HP-UX System Management Homepage (HP SMH). Each VLAN interface created is assigned a VLAN PPA (VPPA) that is unique across the system and a VLAN ID, that identifies the virtual LAN it is part of. The VLAN ID is unique on the interface on which the VLAN interface is created. WARNINGS
The and commands are deprecated. These commands will be removed in a future HP-UX release. HP recommends the use of replacement command nwmgr(1M) to perform all network interface-related tasks. SEE ALSO
