Full Discussion: Search and Replace with Confirmation
Top Forums Shell Programming and Scripting Search and Replace with Confirmation Post 302390136 by Abhinav Tyagi on Wednesday 27th of January 2010 03:27:38 AM

I understand your point
but if I use my sed command in
Code:
if [ grep /abc/ filename];then
   if [ "$ANSWER" == "Y" ];then
     #Run the Sed Command
   else
      #Exit the loop
   fi
fi

then this would be asking confirmation for replacing text at some position or whole in a file...

I want to know how can I use SED command to replace each occurence only with confirmation from the user.

eg.

let this be some text in file

Code:
apple boy cat dog
boy dog apple apple cat
...
...

script should display

do you want to replace "apple" with "APPLE()" in line
apple boy cat dog (y/n)

say n

again
do you want to replace "apple" with "APPLE()" in line (for first occurrence)
boy dog apple apple cat (y/n)

say y

again
do you want to replace "apple" with "APPLE()" in line (for second occurrence)
boy dog APPLE() apple cat (y/n)

say n

and so on



Can this be achieved using SED or any other command ???

gss

gss(5)							      BSD File Formats Manual							    gss(5)

NAME

     gss -- how to configure gss framework

DESCRIPTION

     The gss GSS.frameworks have several configuration domains, all can configured with defaults(1).

     Configuration can be stored both in the user's configuration ( ~/Library/Preferences) and system ( /Library/Preferences ).

CONFIGURATION OPTIONS

     Use gsstool(1) to list the supported options and their settings:
	   gsstool supported-mech --options

     Common options are:

     NTLM 'Force NTLMv1'
	     Force client to use NTLMv1

     NTLM NTLMv1
	     Enable support for NTLMv1 in both client and server

     NTLM NTLMv2
	     Enable support for NTLMv2 in both client and server

     NTLM 'NTLM session key'
	     Require backends to support for NTLMv2 session key, Lion and earlier dont support this.  Session keys is required for NTLM MIC that
	     stops reflection attacks.

     NTLM 'AllowedHosts'
	     What hosts that NTLM is allowed to be used for. When there a host that is not on the list, NTLM will not be used. File globbing is
	     used when matching and it's case insensitive.  When there is no configuration, all hosts are allowed.

	     defaults write com.apple.GSS.NTLM AllowedHosts -array host.local '*.my.domain'

NTLM options
     If you want to disable NTLM support completely in both the acceptor (server) and initiator (client), you need disable both NTLMv1 and NTLMv2,
     and set their values to boolean false or 0.

     defaults write com.apple.GSS.NTLM NTLMv1 -bool false
     defaults write com.apple.GSS.NTLM NTLMv2 -bool false

APPLE MAC OS X

     You can use the defaults write command to change the options, for simple boolean options, use this:
	   defaults write com.apple.GSS.NTLM NTLMv1 -bool false

     You can also turn on debugging (output in syslog) using:
	   defaults write com.apple.GSS DebugLevel -int 10
	   open -a Console
