How to extract multiple line in a paragraph? Please help.
Hi all,
The following lines are taken from a long paragraph:
How can I extract some lines starting from "1\1\GINC-COMPUTE-1-3..." to the END???
like this:
I searched in this forum and found a script "
If there is a blank line before the line "1\1\GINC-COMPUTE-1-3"", it should work.
Unfortunately, there is no blank line before the line "1\1\GINC-COMPUTE-1-3"". How can I modify this script?
Eventually, I want to get a coordinate file like this:
Is that possible? I think it would be a tough task to do with "awk".
Please help. Thanks a lot!

rrdupdate
RRDUPDATE(1) rrdtool RRDUPDATE(1)NAME
rrdupdate - Store a new set of values into the RRD
SYNOPSIS
rrdtool {update | updatev} filename [--template|-t ds-name[:ds-name]...] [--daemon address] [--] N|timestamp:value[:value...] at-
timestamp@value[:value...] [timestamp:value[:value...] ...]
DESCRIPTION
The update function feeds new data values into an RRD. The data is time aligned (interpolated) according to the properties of the RRD to
which the data is written.
updatev This alternate version of update takes the same arguments and performs the same function. The v stands for verbose, which describes
the output returned. updatev returns a list of any and all consolidated data points (CDPs) written to disk as a result of the
invocation of update. The values are indexed by timestamp (time_t), RRA (consolidation function and PDPs per CDP), and data source
(name). Note that depending on the arguments of the current and previous call to update, the list may have no entries or a large
number of entries.
Since updatev requires direct disk access, the --daemon option cannot be used with this command.
filename
The name of the RRD you want to update.
--template|-t ds-name[:ds-name]...
By default, the update function expects its data input in the order the data sources are defined in the RRD, excluding any COMPUTE
data sources (i.e. if the third data source DST is COMPUTE, the third input value will be mapped to the fourth data source in the
RRD and so on). This is not very error resistant, as you might be sending the wrong data into an RRD.
The template switch allows you to specify which data sources you are going to update and in which order. If the data sources
specified in the template are not available in the RRD file, the update process will abort with an error message.
While it appears possible with the template switch to update data sources asynchronously, RRDtool implicitly assigns non-COMPUTE
data sources missing from the template the *UNKNOWN* value.
Do not specify a value for a COMPUTE DST in the update function. If this is done accidentally (and this can only be done using the
template switch), RRDtool will ignore the value specified for the COMPUTE DST.
--daemon address
If given, RRDTool will try to connect to the caching daemon rrdcached at address and will fail if the connection cannot be
established. If the connection is successfully established the values will be sent to the daemon instead of accessing the files
directly.
For a list of accepted formats, see the -l option in the rrdcached manual.
N|timestamp:value[:value...]
The data used for updating the RRD was acquired at a certain time. This time can either be defined in seconds since 1970-01-01 or
by using the letter 'N', in which case the update time is set to be the current time. Negative time values are subtracted from the
current time. An AT_STYLE TIME SPECIFICATION (see the rrdfetch documentation) may also be used by delimiting the end of the time
specification with the '@' character instead of a ':'. Getting the timing right to the second is especially important when you are
working with data-sources of type COUNTER, DERIVE or ABSOLUTE.
When using negative time values, options and data have to be separated by two dashes (--), else the time value would be parsed as
an option. See below for an example.
When using negative time values, options and data have to be separated by two dashes (--), else the time value would be parsed as
an option. See below for an example.
The remaining elements of the argument are DS updates. The order of this list is the same as the order the data sources were
defined in the RRA. If there is no data for a certain data-source, the letter U (e.g., N:0.1:U:1) can be specified.
The format of the value acquired from the data source is dependent on the data source type chosen. Normally it will be numeric, but
the data acquisition modules may impose their very own parsing of this parameter as long as the colon (:) remains the data source
value separator.
ENVIRONMENT VARIABLES
The following environment variables may be used to change the behavior of "rrdtool update":
RRDCACHED_ADDRESS
If this environment variable is set it will have the same effect as specifying the "--daemon" option on the command line. If both are
present, the command line argument takes precedence.
EXAMPLES
o "rrdtool update demo1.rrd N:3.44:3.15:U:23"
Update the database file demo1.rrd with 3 known and one *UNKNOWN* value. Use the current time as the update time.
o "rrdtool update demo2.rrd 887457267:U 887457521:22 887457903:2.7"
Update the database file demo2.rrd which expects data from a single data-source, three times. First with an *UNKNOWN* value then with
two regular readings. The update interval seems to be around 300 seconds.
o "rrdtool update demo3.rrd -- -5:21 N:42"
Update the database file demo3.rrd two times, using five seconds in the past and the current time as the update times.
o "rrdtool update --cache /var/lib/rrd/demo3.rrd N:42"
Update the file "/var/lib/rrd/demo3.rrd" with a single data source, using the current time. If the caching daemon cannot be reached, do
not fall back to direct file access.
o "rrdtool update --daemon unix:/tmp/rrdd.sock demo4.rrd N:23"
Use the UNIX domain socket "/tmp/rrdd.sock" to contact the caching daemon. If the caching daemon is not available, update the file
"demo4.rrd" directly. WARNING: Since a relative path is specified, the following disturbing effect may occur: If the daemon is
available, the file relative to the working directory of the daemon is used. If the daemon is not available, the file relative to the
current working directory of the invoking process is used. This may update two different files depending on whether the daemon could
be reached or not. Don't do relative paths, kids!
