Previous command
Hi,
i would like to retrieve (only retrieve, not execute) a previous command which i executed on the command prompt. I tried the 'up arrow' key, but its not working. Instead,it showed me some funny characters. I searched around and i found the way to do it was using the way below. Several websites quoted as saying ".. using control key ^P .. ". What keys do i type to get the control P ? I tried shift + P and Ctrl + P, neither worked.

getdnskeys
GETDNSKEYS(1p) User Contributed Perl Documentation GETDNSKEYS(1p)
NAME
getdnskeys - Manage lists of DNSKEYs from DNS zones
SYNOPSIS
getdnskeys [-i file] [-o file] [-k] [-T] [-t] [-v] [zones]
DESCRIPTION
getdnskeys manages lists of DNSKEYs from DNS zones. It may be used to retrieve and compare DNSKEYs. The output from getdnskeys may be
included (directly or indirectly) in a named.conf file.
OPTIONS
getdnskeys takes the following options:
-i path
Reads path as a named.conf with which to compare key lists.
-k Only looks for Key Signing Keys (KSKs); all other keys are ignored.
-o file
Writes the results to file.
-T Checks the current trusted key list from named.conf.
-t Encloses output in needed named.conf syntax markers.
-v Turns on verbose mode for additional output.
-Version
Displays the version information for getdnskeys and the DNSSEC-Tools package.
-h Gives a help message.
EXAMPLES
This getdnskeys will retrieve the KSK for example.com:
getdnskeys -o /etc/named.trustkeys.conf -k -v -t example.com
This getdnskeys will check saved keys against a live set of keys:
getdnskeys -i /etc/named.trustkeys.conf -T -k -v -t
This getdnskeys will automatically update a set of saved keys:
getdnskeys -i /etc/named.trustkeys.conf -k -t -T -v
-o /etc/named.trustkeys.conf
SECURITY ISSUES
Currently this does not validate new keys placed in the file in any way, nor does it validate change over keys which have been added.
It also does not handle revocation of keys.
It should prompt you before adding a new key so that you can always run the auto-update feature.
