Thanks rajkumarin, this works to extract the right value, but extract all the values and not in uniquely way. Plus, is it possibile to "sed" a variable instead of file (text)?
Hi
I want to extract certain text between two line numbers like
23234234324 and
54446655567567
How do I do this with a simple sed or awk command?
Thank you.

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 have a text file that has many lines, and for each line I need to extract different sections of text, then write several variables from the data.
I can split out the various sections by selecting their position on each line as the column sizes will never vary.

mysqldumpslow
MYSQLDUMPSLOW(1) MySQL Database System MYSQLDUMPSLOW(1)NAME
mysqldumpslow - Summarize slow query log files
SYNOPSIS
mysqldumpslow [options] [log_file ...]
DESCRIPTION
The MySQL slow query log contains information about queries that take a long time to execute (see Section 5.2.5, "The Slow Query Log").
mysqldumpslow parses MySQL slow query log files and prints a summary of their contents.
Normally, mysqldumpslow groups queries that are similar except for the particular values of number and string data values. It "abstracts"
these values to N and 'S' when displaying summary output. The -a and -n options can be used to modify value abstracting behavior.
Invoke mysqldumpslow like this:
shell> mysqldumpslow [options] [log_file ...]
mysqldumpslow supports the following options.
o --help
Display a help message and exit.
o -a
Do not abstract all numbers to N and strings to 'S'.
o --debug, -d
Run in debug mode.
o -g pattern
Consider only queries that match the (grep-style) pattern.
o -h host_name
Host name of MySQL server for *-slow.log file name. The value can contain a wildcard. The default is * (match all).
o -i name
Name of server instance (if using mysql.server startup script).
o -l
Do not subtract lock time from total time.
o -n N
Abstract numbers with at least N digits within names.
o -r
Reverse the sort order.
o -s sort_type
How to sort the output. The value of sort_type should be chosen from the following list:
o t, at: Sort by query time or average query time
o l, al: Sort by lock time or average lock time
o r, ar: Sort by rows sent or average rows sent
o c: Sort by count
By default, mysqldumpslow sorts by average query time (equivalent to -s at).
o -t N
Display only the first N queries in the output.
o --verbose, -v
Verbose mode. Print more information about what the program does.
Example of usage:
shell> mysqldumpslow
Reading mysql slow query log from /usr/local/mysql/data/mysqld51-apple-slow.log
Count: 1 Time=4.32s (4s) Lock=0.00s (0s) Rows=0.0 (0), root[root]@localhost
insert into t2 select * from t1
Count: 3 Time=2.53s (7s) Lock=0.00s (0s) Rows=0.0 (0), root[root]@localhost
insert into t2 select * from t1 limit N
Count: 3 Time=2.13s (6s) Lock=0.00s (0s) Rows=0.0 (0), root[root]@localhost
insert into t1 select * from t1
