sed hash in multiple lines
Hi everybody,

I am writing a little script to manage keystores and need some help with sed.

The output of the keystore file is like:

Code:
vi 2, Dec 7, 2012, trustedCertEntry,
Certificate fingerprint (MD5): F9:1F:FE:E6:A3:CB:99:88:44:D4:67:ED:G5:F8:97:7A
system@remote-server, Dec 17, 2013, PrivateKeyEntry,
Certificate fingerprint (MD5): 2A:DD:4B:C5:AD:B0:MF:96:51:B0:14:4A:B5:6C:99:FB
verisign intermediate 1, Dec 7, 2012, trustedCertEntry,
Certificate fingerprint (MD5): 4E:F6:A0:FC:40:0C:AE:9C:05:2F:AE:99:C6:7D:37:9F

So what I want, is the hash sum of "system@remote-server" (e.g. 2A:DD:4B:C5:AD:B0:MF:96:51:B0:14:4A:B5:6C:99:FB)

What I tried as far is:

sed -e "system@remote-server.*PrivateKeyEntry,/,/Certificate fingerprint.*:[a-zA-Z0-9]{2}$/ {/\([[a-zA-Z0-9]{2}[:]]*[a-zA-Z0-9]{2}$\)/\1/p}"

and

sed -n "s/system@remote-server.*PrivateKeyEntry.*Certificate fingerprint:*([a-zA-Z0-9_-]): \([[a-zA-Z0-9]{2}[:]]*[a-zA-Z0-9]{2}$\)/\1/p"

but I don't get any output for them.

ps: the easy way would be grep -A 1 "system@remote-server.*PrivateKeyEntry" | tail -1 | cut -f 4 -d " ", but it is not reliable. Therefore I want to do it with sed.

Does anybody have a solution for me?

Thank you all in advance and regards
Hamss

Hello,

Could you please use the following code for same.


Code:
awk '/system@remote-server, Dec 17, 2013, PrivateKeyEntry,/ {getline; print $0}' file_name | sed 's/Certificate fingerprint (MD5): //g'

Output will be as folllows.


Code:
2A:DD:4B:C5:AD:B0:MF:96:51:B0:14:4A:B5:6C:99:FB


Thanks,
R. Singh

Hi,
In sed:
Code:
sed -n -e '/system@remote-server.*PrivateKeyEntry/,/Certificate fingerprint/{/system@remote-server.*PrivateKeyEntry/d;s/.* \([0-9A-F]\+:\)/\1/p;}'

Simplified:
Code:
sed -n -e '/system@remote-server.*PrivateKeyEntry/,/Certificate fingerprint/{/Certificate fingerprint/s/.* \([0-9A-F]\+:\)/\1/p;}'

Because "d" command is not need with "-n" option...(why delete line that we won't print ?)
Regards.

I'm not sure that this solution is possible otherwise the solution will also be possible with grep...

This actually does not work in my case...

Thank you all for the suggestions. I need to play a bit around with them.

General question; Is it possible to merge multiple regex into one?

E.g. for this case.
We have a this hash and want to make a regex ohny for this pattern 2A:DD:4B:C5:AD:B0:MF:96:51:B0:14:4A:B5:6C:99:FB

So I am increasing the patterns, and merging one into an other:
1. pattern: ([A-Z0-1][A-Z0-1]:) set pattern
2. pattern: ([[A-Z0-1][A-Z0-1]:]*) pattern 1 0-infinite times
3. pattern: ([[A-Z0-1][A-Z0-1]:]*[A-Z0-1][A-Z0-1]) and put the last two chars at the end

Is this possible?

Thanks this works good in my case. But I would like to pattern the hash itself. How would you do that?
