Scripting for rhosts format

[Dewa Negara_4]

Hi All,

I want to create a script to generate a neat report for my all rhosts file. For instance, I have a rhosts file as below :

#cat /root/.rhosts

bdhp4337.na.pg.com root
192.44.190.109 root
rshj root # 03152004:RSHJ reporting tool:paul@test.com:NEVER:john@test.com
bdhp4259 root # 03172004:NP1 database server:paul@test.com:NEVER:john@test.com

and I want to generate a report with format as below :

Remote server UserID Justification
-------------------------------------------------------
bdhp4337 root
192.44.190.109 root
rshj root # 03152004:RSHJ reporting tool:paul@test.com:NEVER:john@test.com
bdhp4259 root # 03172004:NP1 database server:paul@test.com:NEVER:john@test.com

How can I do that using a shell scripting?

Pls help. High score will be given.

Best Regards,
Dewa

Hi, Sorry...the attached output is not so clear.

The format should be :

Remote server UserID Justification
bdhp4337 root
192.44.190.109 root

rshj root # 03152004:...
bdhp4259 root # 03172004:...

Hi Dewa
.rhosts file is setting permission for rcp (remote copy).
It is hard to understand for me.
If you want to create script copy file from serverA to serverB.
On serverB edit ~.rhosts file
#vi ~.rhosts
serverA root
at serverA:
#rcp -r -p /path/file_or_dir serverB:/path/

Hi Dewa

If I understand correctly (I hope I do!) try this:

#!/bin/ksh
echo "HOST\tUSER\tCOMMENT" >/tmp/report
cat /root/.rhosts | while read HOST USER COMM
do
COMMENT=`echo $COMM | sed 's/ /_/g'`
echo "$HOST\t$USER\t$COMMENT" >>/tmp/report
done
cat /tmp/report | pr -e15

Note:- We have to pump the comment field through 'sed' to get rid of the spaces. This would cause the output to look strange. You may need to scroll-up to view the output as 'pr' paginates the file.
