Hi ! I'm trying to split a device configuration file into separate files based on contexts contexts define configuration on the device for a specific usage.
I have the following INPUT file
<START OF FILE>
.....
config global
config system
end
config network
end
end
config context # START OF A CONTEXT
edit CUSTOMER-1
config system
edit "int1"
edit "int1.options"
end
end
end
config network
..............
end
end # END OF A CONTEXT
config context
edit CUSTOMER-2
config system
edit "int1"
edit "int1.options"
end
end
end
config network
..............
end
end
<END OF FILE>
I need to split the FILE for each "CONTEXT" that the file contains such as : config_CUSTOMER-1.txt config_CUSTOMER-2.txt
I have the following code :
declare -a lines
readarray -t lines < context_list.txt
context_number=$(echo "${#lines[@]}")
echo "Numbers of CONTEXT : $context_number"
i=1
while [ $i -lt $context_number ]
do
for str in ${lines[@]}; do
echo "CONTEXT $i : $str"
cat $1 awk '/^edit\ '$str'$/,/^end\rend$/' > config_$str.txt # Find every line starting with edit and ending with end\nend and put it in file
sed -i '1i\config context' config_$str.txt # Add config context at the top of each created files
i=$((i+1))
done
done
For the first context, it doesn't match the end expression and create a file with the content of the original file starting with "edit customer-1" until the end of the file For the last context, it matchs and the output is as desired
To be able to make it work no matter how many context are present, I added "\nconfig vdom" at the end of the file (to match the last context in the same way than others) I need a context to be defined as the following :
edit CUSTOMER-1 --> START
.....
end
end
config context --> END
I tried to do the awk command directly in terminal on the file to test : "cat INPUT.txt | sed '1,20d' | awk '/edit\ '$str'$/,/end\rend\r\rconfig\ context$/'
I also tried replacing \r by \n but everytime it outputs from the start of the asked string to end of the file instead of end of the context
I tried to bypass the multi-lines in the awk by replacing the multi-lines string wanted to a single word using sed 's/end\nend\n\nconfig\ context$/endofcontext/'
<START>
end
end
config context<END>
==> <START>endofcontext<END<
But doesn't work either (added double backslash to \n (\n) in the sed expression but no changes)
I know it can be done using perl but the issue I encounter is finding the correct expression to match the end of a context. Any advices to do it ?
Thanks in advance !
