File modification help: without manual editing through vi :
Hi Experts,

I want to edit a file from a selected pattern range, please advise how to accomplish from command line, without going vi and doing it manually:


portion of the file given below: (red want to remove and save )
1. I know the interface number is lan5:5 , that need to match first.
2. I want to get the pattern for this , i.e the instance number for the line containing lan5:5 is is [8] in this case.
3. I want to remove all the entries for instance number : [8]
Code:
 want to delete from line IP_ADDRESS[8]="10.140.220.62"  to  DHCP_ENABLE[8]="0"  line.



Code:
BROADCAST_ADDRESS[5]="10.140.236.255"
INTERFACE_STATE[5]="up"
DHCP_ENABLE[5]="0"
INTERFACE_MODULES[5]=""
ROUTE_DESTINATION[2]=default
ROUTE_GATEWAY[2]=10.40.118.4
ROUTE_COUNT[2]=1
INTERFACE_NAME[8]="lan5:5"
IP_ADDRESS[8]="10.140.220.62"
SUBNET_MASK[8]="255.255.255.0"
BROADCAST_ADDRESS[8]="10.140.220.255"
INTERFACE_STATE[8]="up"
DHCP_ENABLE[8]="0"
INTERFACE_MODULES[8]=""
INTERFACE_NAME[10]="lan5:7"
IP_ADDRESS[10]="10.140.239.62"
SUBNET_MASK[10]="255.255.255.0"
BROADCAST_ADDRESS[10]="10.140.239.255"
INTERFACE_STATE[10]="up"
DHCP_ENABLE[10]="0"




The output in the file should be like this after deleting the patterns:



Code:
BROADCAST_ADDRESS[5]="10.140.236.255"
INTERFACE_STATE[5]="up"
DHCP_ENABLE[5]="0"
INTERFACE_MODULES[5]=""
ROUTE_DESTINATION[2]=default
ROUTE_GATEWAY[2]=10.40.118.4
ROUTE_COUNT[2]=1
INTERFACE_NAME[10]="lan5:7"
IP_ADDRESS[10]="10.140.239.62"
SUBNET_MASK[10]="255.255.255.0"
BROADCAST_ADDRESS[10]="10.140.239.255"
INTERFACE_STATE[10]="up"
DHCP_ENABLE[10]="0"


Thanks,

You problem statement is not clear. If you mean that want to delete every line from your input file that contains the string "[8]", the following script will remove that set of lines from the file named by the argument passed to the script:
Code:
#!/bin/ksh
ex -s "$1" <<-EOF
        :g/[[]8[]]/d
        :wq
EOF

In a while read loop, you could
check the line for [8] then
echo line >> ip_stuff_file_name
otherwise
echo line >> not_ip_stuff_file_name
end check
done

move original_file_name to original_file_name_backup
move the not_ip_stuff_file_name to original_file_name



As usual, you want to run it on test data files only, until you are sure of the results.

There might be more elegant ways, but that's the first thing that came to mind.

Don,
Thanks,
The desired script should find lan5:5 , and then to decide the [8] string, then remove all the lines having [8] entires. Can we put the condition for finding lan5:5 and then do the editing on the file to remove the lines.
- As without seeing the file I do not know if the lines I am going to remove has the pattern of [8] , but what I know is lan5:5 . Hope you got it.

Code:
BROADCAST_ADDRESS[5]="10.140.236.255"
INTERFACE_STATE[5]="up"
DHCP_ENABLE[5]="0"
INTERFACE_MODULES[5]=""
ROUTE_DESTINATION[2]=default
ROUTE_GATEWAY[2]=10.40.118.4
ROUTE_COUNT[2]=1
INTERFACE_NAME[8]="lan5:5"
IP_ADDRESS[8]="10.140.220.62"
SUBNET_MASK[8]="255.255.255.0"
BROADCAST_ADDRESS[8]="10.140.220.255"
INTERFACE_STATE[8]="up"
DHCP_ENABLE[8]="0"
INTERFACE_MODULES[8]=""
INTERFACE_NAME[10]="lan5:7"
IP_ADDRESS[10]="10.140.239.62"
SUBNET_MASK[10]="255.255.255.0"
BROADCAST_ADDRESS[10]="10.140.239.255"
INTERFACE_STATE[10]="up"
DHCP_ENABLE[10]="0"

I'm sorry, but I don't understand your requirements. It is obvious that we have a language barrier. Are you saying that you:
  1. want to find a line that contains lan5:5,
  2. find a digit string between [ and ] on that line, and then
  3. remove every line in the file that contains that digit string between [ and ]?

Don,
>Are you saying that you:
- yes, this is corrrect .

1. want to find a line that contains lan5:5 ,
2. find a digit string between [ and ] on that line, and then
3. remove every line in the file that contains that digit string between [ and ] ?

Thank you..

I wonder if GNU 'sed -i' would work for you. Note that vi in : modes is ex, vi is visual ex, and both vi and ex drive OK in scripts. sed is a stream version of ex. sed -i makes a temp file and then swaps files. (sed ... old_file >/tmp/xrandom ; mv -f /tmp/xrandom old_file)
Code:
sed -i '/^INTERFACE_NAME\[8\]="lan5:5"$,/^INTERFACE_MODULES\[8\]=""$/d'

To delete by index takes two passes, one to find the index and another to remove those lines.
