need assistance ----SH schell script
Hello All,
I need to develop a script(SH]) to generate a comparison file between two files old and new file.The script takes in parameter the old file path and the new file path. And the script generates a file containing the comparison between the two files with this details:
- Keys added on the new file (key=value)
- Keys modified on the new file (key=value)
- Keys deleted on the new file (key=value)
key column is the 4th one and value column is the 6th one in the sample file.
Example:
old file: key1,value1 new file:key4,value3
key4,value4 key6,value6
output file: comparison file
------------------
1> keys added ----- key6,value6
2>deleted ---------- key1,value1
3> modified---------- key4,value3
I'm new to schell scripting field. request you to explain briefly along with the code. any sort of assistance would be appreciated.
Thanks in advance
Regards Shahid.

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. perl v5.14.2 2012-06-21 GETDNSKEYS(1p)
