I regularly extract lines of text from files based on the presence of a particular keyword; I place the extracted lines into another text file. This takes about 2 hours to complete using the "sort" command then Kate's find & highlight facility.
I've been reading the forum & googling and can find scripts and shell commands which extract a particular string from a file but nothing that extracts a complete line based on a keyword/string within a line.
Here's an example of the lines of data I'm using:
The data is alway a list item.
I need something that will find the line containing a specified category which will then extract the complete line and move it to a new text file (preferably named after that category). For example:
If I search for "<b >CategoryOne</b >" then I need it to move every line containing "<b >CategoryOne</b >" to text file categoryone.txt

patterns(4) Kernel Interfaces Manual patterns(4)NAME
patterns - Patterns for use with internationalization tools
SYNOPSIS
See the Description section.
DESCRIPTION
The patterns file contains the patterns that must be matched for the internationalization tools extract, strextract, and strmerge.
The pattern file in the following example is the default patterns file located in /usr/lib/nls/patterns.
# This is the header to insert at the beginning of the first new # source file
$SRCHEAD1 (1) #include <nl_types.h> nl_catd _m_catd;
# The header to insert at the beginning of the rest of the new # source files
$SRCHEAD2 (2) #include <nl_types.h> extern nl_catd _m_catd;
# This is the header to insert at the beginning of the message # catalogues
$CATHEAD (3) $ /* $ * X/OPEN message catalogue $ */ $quote "
# This is how patterns that are matched will get rewritten.
$REWRITE (4) catgets(_m_catd, %s, %n, %t)
# Following is a list of the sort of strings we are looking for. # The regular expression syntax is based on regexp(3).
$MATCH (5)
# Match on strings containing an escaped " "[^\]*\"[^"]*"
# Match on general strings "[^"]*"
# Now reject some special C constructs.
$REJECT (6) # the empty string ""0
# string with just one format descriptor "%." "%.."
# string with just line control in "\."
# string with just line control and one format descriptor in "%.\." "\.%."
# ignore cpp include lines #[ ]*include[ ]*".*" #[ ]*ident[ ]*".*"
# reject some common C functions and expressions with quoted # strings [sS][cC][cC][sS][iI][dD][][ ]*=[ ]*".*" open[ ]*([^,]*,[^)]*)
creat[ ]*([^,]*,[^)]*) access[ ]*([^,]*,[^)]*) chdir[ ]*([^,]*,[^)]*) chmod[ ]*([^,]*,[^)]*) chown[ ]*([^,]*,[^)]*)
# Reject any strings in single line comments /*.**/
# Print a warning for initialised strings.
$ERROR initialised strings cannot be replaced (7) char[^=]*=[ ]*"[^"]*" char[^=]*=[ ]*"[^\]*\"[^"]*" char[ ]***[A-Za-z][A-Za-
z0-9]*[[^]*][ ]*=[ {]*"[^"]*" char[ ]***[A-Za-z][A-Za-z0-9]*[[^]*][ ]*=[ {]*"[^\]*\"[^"]*"
The default patterns file is divided into the following sections: In the $SRCHEAD1 section, the strmerge and extract commands place text in
this section at the beginning of the first new source program, which is prefixed by nl_. These commands define the native language file
descriptors that point to the message catalog. In the $SRCHEAD2 section, the strmerge and extract commands place text in this section at
the beginning of the second and remaining source programs. These commands also define the native language file descriptors that point to
the message catalog. $SRCHEAD2 contains the external declaration of the nl file descriptor. In the $CATHEAD section, the strmerge and
extract commands place text in this section at the beginning of the message catalog. In the $REWRITE section, you specify how the strmerge
and extract commands should replace the extracted strings in the new source program. You can supply three options to the catgets command:
This option increments the set number for each source. This option applies only if you are using the strmerge command. For more informa-
tion on set numbers, see the catgets(3) reference page. This option increments the message number for each string extracted. This option
applies if you are using either the strmerge or extract commands. This option expands the text from the string extracted. The string can
be a error message or the default string extracted and printed by the catgets command. For example, if you want an error message to appear
when catgets is unable to retrieve the message from the message catalog, you would include the following line: catgets(_m_catd, %s, %n,
"BAD STRING")
When catgets fails, it returns the message BAD STRING. In the $MATCH section, you specify the patterns in the form of a regular
expression that you want the strextract, strmerge, and extract commands to find and match. The regular expression follows the same
syntax rules as defined in regexp(3) reference page. In the $REJECT section, you specify the matched strings that you do not want
the strmerge and extract commands to replace in your source program. The regular expression follows the same syntax rules as
defined in regexp(3) reference page. In the $ERROR section, the strextract, strmerge, and extract commands look for bad matches and
notify you with a warning message. The regular expression follows the same syntax rules as defined in the regexp(3) reference page.
