Full Discussion: Replace text in a file
Top Forums Shell Programming and Scripting Replace text in a file Post 302970833 by rdrtx1 on Tuesday 12th of April 2016 09:48:27 AM

Is $filename name /tmp/odbc.ini.2014_old or /tmp/odbc.ini_old?

The code shown above will remove the line matching the string. For replacing string try updating to:
Code:
#!/usr/bin/perl

use strict;
use warnings;

my $filename = '/tmp/odbc.ini.2014_old';
my $find=' sql7.0.1 ';
my $replace = ' sqls715 ';

{
   local @ARGV =($filename);
   local $^I ='.bac';
   while (<>) {
      if (s/$find/$replace/ig) {
         print;
      } else {
         print;
      }
   }
}
print "Finished\n";

(after the $filename is verified)

NAME

       odbcinst - An unixODBC tool for manipulating configuration files

SYNOPSIS

       odbcinst ACTION OBJECT OPTIONS

DESCRIPTION

       odbcinst  is  a	command line tool which has been created for allowing people who are developing the install scripts/RPMs for Drivers to be
       able to easily create/remove entries in odbc.ini and odbcinst.ini. This command line tool is a complement to the shared library of the same
       name (libodbcinst.so). This tool is a part of the odbcinst component of unixODBC.

OPTIONS

   ACTIONS
       -i     Install (add section to config file) new OBJECT.

       -u     Uninstall (remove section from config file) existing OBJECT.

       -q     Query the config files and print the options for specified OBJECT.

       -j     Prints current configuration of unixODBC, listing (among others) the paths to the configuration files.

       -c     Calls SQLCreateDataSource

       -m     Calls SQLManageDataSources

       --version
	      Prints program version and exits.

   OBJECTS
       -d     The ACTION affect drivers (and thus the odbcinst.ini configuration file).

       -s     The ACTION affect data sources (and thus the user or system odbc.ini configuration file).

   OPTIONS
       -f FILE
	      The FILE is template file, describing the configuration of installed OBJECT (only valid for the -i ACTION).

       -r     Same as the -f OPTION, only take the standard input as the template file.

       -n NAME
	      Specifies the NAME of the OBJECT.

       -v     Turn off verbose mode. This turns off all information, warning and error messages.

       -l     The specified data source is system-wide. Has any effect only with the -s OBJECT.

       -h     The specified data source is user-specific. Has any effect only with the -s OBJECT.

RETURN VALUES

       This command returns zero on success and non-zero value on failure.

FILES

       /etc/odbinst.ini
	      Configuration file containing all the database drivers specifications. See odbcinst.ini(5) for more details.

       /etc/odbc.ini
	      System-wide data sources specifications. See odbc.ini(5) for more details.

       $HOME/.odbc.ini
	      User-specific data sources specifications. See odbc.ini(5) for more details.
