How to change a file association with command line in Windows system (XP, Vista, 7)?

To change a file association with command line in Windows system (XP, Vista, 7)

Two commands are involved, assoc & ftype.

Example No1: 

We want to use Notepade++ to open text file instead of Notepad.

C:\assoc .txt

.txt=txtfile

C:\ftype txtfile

txtfile=%SystemRoot%\system32\NOTEPAD.EXE %1

ftype txtfile="C:\Program Files\Notepad++\notepad++.exe" "%1"

 

Example No2:

We have a customized application, ezPGPClient, which can encrypt and decrypt files with PGP standard.

It's located in C:\pnab\program\ezpgp\ezPGPClient.exe

The file extensions will be associated are .gpg and .pgp and there is no other program had been set up to association with them.

C:\assoc .gpg=pgpfile

# This command assign .gpg to be pgpfile

 

C:\assoc .pgp=pgpfile

# This command assign .pgp to be pgpfile

 

C:\ftype pgpfile=C:\pnab\program\ezpgp\ezPGPClient.exe %1

# This command assign pgpfile to be opened by the given program with absolute path.

find how many keys are in key server

To find how many keys are in key server, please run this command in each server.

ldapsearch -H ldap://127.0.0.1 -x -b "ou=PGP Keys,dc=tsmc,dc=com" "(pgpUserID=*)" pgpKeyID -LLL | grep pgpKeyID |wc -l

 

If you want to compare the result on both server, please run this command in each server and redirect the output to a text file.

ldapsearch -H ldap://127.0.0.1 -x -b "ou=PGP Keys,dc=tsmc,dc=com" "(pgpUserID=*)" pgpKeyID -LLL | grep pgpKeyID | sort

How to check if my text or script does have “carrage return” CR in Linux

For example, I have a script called myscript.sh

Command:

$ cat –v myscript.sh

If I forgot to convert it into Unix format, I would have a output like this:

#! /bin/bash^M
^M
echo "Steve"^M
echo "Test"
