Hammer & Screwdriver Grep start and end line of each segments in a file
Cat file1

Code:
--------
----------
SCHEMA.TABLE1
insert-------
update-----
-------------
----------
SCHEMA.TABLE2
insert-------
update-----
-----------
------------
SCHEMA.TABLE3
insert-------
update-----
------------

grep -n SCHEMA > header_file2.txt

Code:
1: SCHEMA.TABLE1  
25:SCHEMA.TABLE2 
30:SCHEMA.TABLE3

I need to print values of each schema content to temp file.

Code:
sed -n '1,24p' file1.txt > file.tmp$$

sed -n '25,29p' file1.txt > file.tmp$$


Question is how can I get the start and ending line in the header file.so h that I can use with sed to place each table contents into file.


Code:
1: SCHEMA.TABLE1  (1-24)
25:SCHEMA.TABLE2  (25-29)
30:SCHEMA.TABLE3  (30-end)

I have below idea but its kind of making it complex. (syntax may not correct)

Code:
1:1:SCHEMA.TABLE1  
2:25:SCHEMA.TABLE2
3:30:SCHEMA.TABLE3

start=1
start1=expr `$start+1`

end=expr `head -$start1 file1 |tail-1 |cut-d':' -f2`-1  (24) 

sed '1, $end' > tmp

start=2
start1=expr `$start+1`

end=expr`head -3 $start1 |tail-1 |cut-d':' -f2`-1  (29)

sed '1, $end' > tmp


Regards,
Veera

gsettings-schema-convert

GSETTINGS-SCHEMA-C(1)						   User Commands					     GSETTINGS-SCHEMA-C(1)

NAME

       gsettings-schema-convert - GConf to GSettings schema conversion

SYNOPSIS

       gsettings-schema-convert [option...] {file}

DESCRIPTION

       gsettings-schema-convert converts between GConf and GSettings schema file formats. Note that the conversion is not expected to be fully
       automated. You are expected to verify and edit the result of the conversion.

       Note that GSettings schemas need to be converted into binary form with glib-compile-schemas before they can be used by applications.

   Options
       -h, --help
	   Print help and exit

       -o OUTPUT, --output=OUTPUT
	   Store the generated output in the file OUTPUT. If no output file is specified, the generated output is written to stdout.

       -f, --force
	   Overwrite the output file if it already exists.

       -g, --gconf
	   The input file is a GConf schema.

       -s, --simple
	   Produce a GSettings schema in simple format. The simple format is easier to edit and can be converted into the XML format with
	   gsettings-schema-convert later on.

       -x, --xml
	   Produce a GSettings schema in XML format. If the output format is not explicitly specified, this is the default.

       -i ID, --schema-id=ID
	   Use ID as the schema id in the generated GSettings schema.

       -d DOMAIN, --gettext-domain=DOMAIN
	   Use DOMAIN as the gettext domain in the generated GSettings schema.

       -u, --keep-underscores
	   Keep underscores in key names instead of replacing them with dashes. GSettings keys should not contain any underscore.

SEE ALSO

       gsettings-data-convert(1) a related command to migrate user settings from GConf to GSettings.
