Help with hp configuration script (ksh)
Hi
I am writting a configuration script to make changes to the /etc/rc.config.d/nddconf file. I have pulled this section out to test it so I have the editing of the file already written.

I have two problems with the function.
1. The script is ignoring the results of the if loop.
2. The sed line doesn't delete

Code:
function test_ndd {
cd /tmp/PCI
cp /etc/rc.config.d/nddconf /tmp/nddconf
 
for ndd1 in $(<nddentries)
do
  if [ $(grep -c "$ndd1" /tmp/nddconf)!=0 ]
# This line is meant to check to see if the file already contains $ndd1 if it 
# does I need it to delete it from the list
  then
    echo " needs adding !"
  else
    echo $ndd1
    sed -e /"$ndd1"/d nddentries
# This line is meant to delete it from the nddentries list.
  fi
done
}
test_ndd

nddentries file contains
Code:
tcp_syn_rcvd_max
arp_cleanup_interval
ip_forward_src_routed
ip_forward_directed_broadcasts
ip_respond_to_timestamp
ip_respond_to_timestamp_broadcast
ip_respond_to_address_mask_broadcast
ip_respond_to_echo_broadcast
ip_forwarding

Here is the result of running the script
Code:
[root@testing] # ./test_ndd.sh
+ test_ndd
+ count=1
+ cd /tmp/PCI
+ grep -c tcp_syn_rcvd_max /tmp/nddconf
+ [ 0!=0 ]
+ echo  needs adding !
 needs adding !
+ grep -c arp_cleanup_interval /tmp/nddconf
+ [ 2!=0 ]
+ echo  needs adding !
 needs adding !
+ grep -c ip_forward_src_routed /tmp/nddconf
+ [ 1!=0 ]
+ echo  needs adding !
 needs adding !
+ grep -c ip_forward_directed_broadcasts /tmp/nddconf
+ [ 1!=0 ]
+ echo  needs adding !
 needs adding !
+ grep -c ip_respond_to_timestamp /tmp/nddconf
+ [ 2!=0 ]
+ echo  needs adding !
 needs adding !
+ grep -c ip_respond_to_timestamp_broadcast /tmp/nddconf
+ [ 1!=0 ]
+ echo  needs adding !
 needs adding !
+ grep -c ip_respond_to_address_mask_broadcast /tmp/nddconf
+ [ 1!=0 ]
+ echo  needs adding !
 needs adding !
+ grep -c ip_respond_to_echo_broadcast /tmp/nddconf
+ [ 1!=0 ]
+ echo  needs adding !
 needs adding !
+ grep -c ip_forwarding /tmp/nddconf
+ [ 1!=0 ]
+ echo  needs adding !
 needs adding !
[root@testing] #

Code:
# if [ $(grep -c "$ndd1" /tmp/nddconf)!=0 ]
# Why not :
if grep "$ndd1" /tmp/nddconf

Code:
# sed -e /"$ndd1"/d nddentries
# Why not :
sed "/$ndd1/d" nddentries

You should put spaces around the !=
Code:
if [ $(grep -c "$ndd1" /tmp/nddconf) != 0 ]
then

Alternatively:
Code:
if grep "$ndd1" /tmp/nddconf > /dev/null
then

Sadly that didn't work either although I have noticed that it is picking up the commented out examples earlier in the file so I need to exclude lines beginning with a # as well.

Looking to see what other options I can use.

I am not set on using if and sed. (although it is annoying as they should work! )

You could probably use this:
Code:
if grep "^[^#]*$ndd1" /tmp/nddconf >/dev/null
then

Or perhaps you could give this a try as an alternative for the script:
Code:
cd /tmp/PCI
cp /etc/rc.config.d/nddconf /tmp/nddconf
awk -F= 'NR==FNR {if($1!~/^#/)A[$2]=1;next}!A[$1]' /tmp/nddconf nddentries > nddentries.missing
