If I want to put only the entries Email and Age in the output file from the desired record, how do I do that? I know 'print' command can do this, but my syntax always goes wrong.
I have a file which is 5 million records. And each records has 412 fields has delimited by "|". So that makes each records to be 2923 bytes long. I wanted to extract specific records like top 100 or 2500 - 5000, 50001 - 10000 etc. from this file.
I tried using head command for top 100 records,... (1 Reply)
I am trying to cut the first 10 characters from a file only if the file has 'xyz' in field 185-188.
I tried this

interface-order
INTERFACE-ORDER(5) resolvconf INTERFACE-ORDER(5)NAME
interface-order - resolvconf configuration file
DESCRIPTION
The file /etc/resolvconf/interface-order is used to control the order in which resolvconf nameserver information records are processed by
those resolvconf update scripts that consult this file. (The name of the file is apt because a resolvconf nameserver information record is
named after the interface with which it is associated.)
The file contains a sequence of shell glob patterns, one per line. The position of a record in the order is the point at which its name
first matches a pattern.
Patterns may not contain whitespace, slashes or initial dots or tildes. Blank lines and lines beginning with a '#' are ignored.
Resolvconf update scripts in /etc/resolvconf/update.d/ that consult this file include the current default versions of dnsmasq, pdnsd and
libc. (Actually they don't read the file directly; they call the utility program /lib/resolvconf/list-records which lists records in the
specified order and omits the names of empty records.)
EXAMPLE
# /etc/resolvconf/interface-order
# Use nameservers on the loopback interface first.
lo*
# Next use records for Ethernet interfaces
eth*
# Next use records for Wi-Fi interfaces
wlan*
# Next use records for PPP interfaces
ppp*
# Last use other interfaces
