I'm having a problem with sorting that -V isn't solving. I have a very well structured set of folder names (shown below with sort -V) that I want to do a version sort but recognizing floating point numbers (see the first two entries). Any advice?
Xe_phi_3.5_eV_tOn_0.5_ns_tOff_20_ns_d_3_um_V_97.4_V
Xe_phi_3.5_eV_tOn_0.5_ns_tOff_20_ns_d_3_um_V_97_V
Xe_phi_3.5_eV_tOn_0.5_ns_tOff_20_ns_d_6_um_V_90_V
Xe_phi_3.5_eV_tOn_0.5_ns_tOff_20_ns_d_6_um_V_153_V
Xe_phi_3.5_eV_tOn_0.5_ns_tOff_20_ns_d_7_um_V_70_V
Xe_phi_3.5_eV_tOn_0.5_ns_tOff_20_ns_d_8_um_V_70_V
Xe_phi_3.5_eV_tOn_0.5_ns_tOff_20_ns_d_8_um_V_80_V

You can apply numeric sort for 15th field if you want to sort by floating point number.
$ cat test.txt | sort -t _ -V -k 1,14 -k 15n

I am trying to create a paragraph style for number lists. Pretty basic, just some customized indents etc. But each item in my list is not sequentially numbered, i.e., each item starts with 1.
Please advise.
Have you looked at "Numbering style" option ?
In my french version, "Suite…" means increment previous number. And "Commencer…" means "Starts at…"

What are the fields in listed order when one makes the call: ls -l in a bash shell. First I know is file type and permissions, next are a series of 4 integers that I do not know or am uncertain about, then is a date permissions were assigned then another integer and a time, then finally the file name. What I really want to know is what are the 4 integers between file permissions and permission assignment dates? The assignment dates follow a format of, ie "Oct 2 03:15"?
Considering the four integers you mention:
Hard Link Count. See this site.
Group of the user that
owns the file. Shouldn't be a number. If you get a number on your
system this would be a non-standard.
User that owns the file. Again, shouldn't be a number.
File size

I use wget -O to get the site text to a specific file.
It saves the file within ONE line. File has about 2 milion characters. After, I would like to remove any other characters different from "directory= ************" format (including quotation mark, **** stand for any text till second quotation mark).
Is there any smart way to acomplish that?
grep -o '"directory= [^"]*"' file
The smartest way would be to pipe it out to a smarter interpreter. Python for instance.
Python has a great regular expressions library at your disposal.

I need to find files with the same (duplicated) content inside them in a given directory. And I need to use shell code.
Try this: BASH
find -type f -exec md5sum '{}' ';' | sort | uniq --all-repeated=separate -w 33 | cut -c 35-
Explanation:
Find all files, calculate their MD5SUM, find duplicates by comparing the MD5SUM, print the names

I would like to split a huge text file into separate text files. I use:
split -l 1000 file.txt split_file
and I will get split_fileaa, split_filebb, etc.
How can I change the extension to be
split_file0.txt, split_file1.txt, etc?
--additional-suffix is what you need for the additional suffix :
split -l 1000 -d --additional-suffix=.txt file.txt split_file
There is a -d option for numeric suffixes.
