Top Forums Shell Programming and Scripting Help with file processing Post 302947914 by Don Cragun on Tuesday 23rd of June 2015 10:23:06 PM

Is the fixed width in bytes or in characters?
What character set are you using?
What shell are you using?
What operating system are you using?

On systems with a version of awk that conforms to the standards:
Code:
awk 'length($0) != 786' file

will print all lines in file that do not contain 786 characters (not counting the terminating <newline> character). If you want the count to include the <newline> character, change the 786 in that script to 785.

On some systems, the awk length() function incorrectly counts bytes instead of counting characters. If the character set you're using contains multi-byte characters (such as UTF-8), the number of bytes in a line may vary even though the number of characters is constant.

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
       *
