Have been trying to develop a script that reads a string from an input file then looks up that string in a reference file to get a number, then inset that number back into the original file at a certain point (_____):
I tried rexx first but it was painfully slow probably because the lookup file is 167K lines long!
What is the fastest way to perform this kind of search in unix and can anyone give an example!

On Linux I checked the CPU... (4 Replies)

nl-pktloc-lookup(8) System Manager's Manual nl-pktloc-lookup(8)NAME
nl-pktloc-lookup - Lookup packet location definitions
SYNOPSIS
nl-pktloc-lookup name
nl-pktloc-lookup --list
DESCRIPTION
nl-pktloc-lookup searches the packet location database for a matching entry. It is used to resolve packet location aliases to their defini-
tion, i.e. alignment, layer, offset, and mask.
OPTIONS -h or --help
Print help text to console and exit.
-v or --version
Print versioning information to console and exit.
-l or --list
List all packet location definitions.
--u32=VALUE
Prints the packet location definition in a special format that is understood by iproute2's u32 selector parser. It will output a u32
selector which will compare the provided value with the value specified by the packet location.
Please note that due to the limitation of u32, it is not possible to use packet locations based on the link layer. nl-pktloc-lookup
will print an error message in this case.
Example:
selector=$(nl-pktloc-lookup --u32 22 tcp.sport)
tc filter add [...] u32 match $(selector) flowid 1:2
