Need Help for remsh script

Peter Lachnitt — Wed, 26 Sep 2001 07:28:39 GMT

Hello all,
I am try to using a script to change lines in the /etc/passwd and /etc/group on dif. servers.
It works on the local server but not on the remote server.

remsh $i \
sed '/kal/s/$/,maierchr,knoerpte/' /etc/group > /etc/tmp_group
/usr/bin/mv /etc/tmp_group /etc/group

sed '/maierchr/s/201/84/g' /etc/passwd > /etc/tmp_passwd
/usr/bin/mv /etc/tmp_passwd /etc/passwd

sed '/knoerpte/s/201/84/g' /etc/passwd > /etc/tmp_passwd
/usr/bin/mv /etc/tmp_passwd /etc/passwd

fi
done

exit 0

Thanks

Peter Gaube

Hi Peter,

You appear to have a quote problem - as it stands, everything after the 1st sed is running locally, so:

remove the double-quote at the end of the first sed and from both ends of the following line. Insert a double-quote at the end of the last mv.

remsh $i \
"sed '/kal/s/$/,maierchr,knoerpte/' /etc/group > /etc/tmp_group
/usr/bin/mv /etc/tmp_group /etc/group
sed '/maierchr/s/201/84/g' /etc/passwd > /etc/tmp_passwd
/usr/bin/mv /etc/tmp_passwd /etc/passwd
sed '/knoerpte/s/201/84/g' /etc/passwd > /etc/tmp_passwd
/usr/bin/mv /etc/tmp_passwd /etc/passwd"

Rgds, Robin.

Hi

Think you have to put your multiple commands
in " ", for example :

remsh $i "cd / ; ls "

And use ; to separate your commands.

When you call remsh for more than one command
you must consider you are in command line and
want your commands string together.

Hi again

I'm also working on scripts using remsh...
I saw that when you ping an unreachable host
return value for ping is 0 like for host you
can ping...

Are you sure about your test on ping's return
value ?

The only way I found was :
if [ -n `ping $i 100 -n 1 | grep "0 packets received"` ]

You can also test with a remsh (remsh $i /bin/ls >/dev/null) it return 0 only if command
was executed...
