trouble understanding file option and command line arguments
Hi,
I am creating a program with the C language that simulates the WC command in Unix. My program needs to count lines, bytes and words. I have not added the code to count bytes and words yet. I am having trouble understanding what the file option/flag '-' does. I can not visualize how it moves through program code. argc and argv look at one line at a time and they only look at what is on the command line. I am not sure how a program is broken up into files for WC to read.
this is the code I have so far:
Right now I have code to just count the lines. I am testing the program on a hello world program below:
when I test the program, I get 0 for line count.

Couple of questions as I try to decipher someones code who left...
What would something coded like this do?

I have a C++ program. I read command line arguments, but if the value is not supplied, I default or make a calculation. Let's say I set it to a default value.
I can code this in several ways. Here I show three ways. What would be the best way for maintaining this code? The program will get very... (2 Replies)
What are the commands to manage ports from my command line.

Opening Ports, Closing Ports, Viewing their status, etc.

:wall:killall -wHi
i need to understand how the -w option works in terms of processes.
If this command is issued does it literally terminate all running processes ..wait for them all to be terminated and then return to standard output ?
Thanks in advance (2 Replies)
I am looking for help in processing of those options: '-n' or '-p'
I understand what they do and how to use them.
But, I would like to use them with more than one file (and without any shell-loop; loading the 'perl' once.)
I did try it and -n works on 2 files.
Question is:
- is it possible to... (6 Replies)
Ok, thank you. Again I'm new to the programming thing, I'm just trying to figure out what exactly it is I need to do. How would I cash out bits? Numerous questions. I'm a dreamer. AI attempts to communicate with me regularly especially through unfinished apps that I'm assuming is my responsibility... (1 Reply)

sgml-spell-checker - SGML spell checker
SYNOPSIS
nsgmls -l yourdoc.sgml | sgml-spell-checker [option] ...
DESCRIPTION
sgml-spell-checker is a tool that you can use to automatically spell-check your SGML documents. One of the advantages of this tool over
some other SGML-aware spell checkers is that it scans your documents in the form in which the SGML parser actually sees it, which means it
is not line-based, system entities are resolved, marked sections are treated appropriately, etc.
Also, this tool can be made aware of particular DTDs, in the sense that it knows not to spell-check the content of elements that do not
represent human-language text, such as <programlisting> in DocBook. An exclusion list for the DocBook DTD is included, others can be added
trivially.
The input to sgml-spell-checker is the text representation of your SGML document's Element Structure Information Set as generated by nsgmls
(from SP or OpenSP; sometimes installed under the name onsgmls). In other words, you need to pipe the output of nsgmls into sgml-spell-
checker as shown in the synopsis. Provide to nsgmls the options you need, such as -c to search more catalogs, -i to include a marked sec-
tion, or more source files. Do not forget the -l option, or you won't get any file or line references for the misspellings.
The second part of the pipe takes a couple of options; see below. Note that if the language of the document does not match your system's
locale settings, you need to use the --language option.
The output of sgml-spell-checker is a list of the words that are misspelled (in the opinion of aspell), together with file name and line
number. Note that the line number designates where the element that contains the word started, not where the word actually is. So most
likely you will have to search a few lines below the indicated location.
OPTIONS --debug
Debug mode. Generates lots of output not of interest to the normal user.
--language=language
Sets the language of the document. (The format depends on the aspell installation, but something like en or en_US should work.) By
default the language is taken from the system locale settings.
--suggestions
Shows correction suggestions for misspelled words.
--dictionary=file
Uses an additional aspell dictionary file. This option may be used multiple times.
--dtd=dtd
Uses the exclusion list for the specified DTD (e.g., docbook).
--help Shows a brief help, then exits.
EXAMPLES
nsgmls -l -D . mydoc.sgml |
sgml-spell-checker --language=en --dtd=docbook
--dictionary=mydict1.aspell --dictionary=mydict2.aspell
(You can enter this command all on one line without the backslashes, or on several lines with the backslashes.)
NOTES
Read the aspell documentation about how to set up the appropriate dictionaries. In case you're having trouble interpreting the aspell doc-
umentation, here's how to make an aspell dictionary file from a flat word list:
rm -f mydict1.aspell # aspell won't overwrite existing files
aspell --language-tag=xx create master ./mydict1.aspell < mywordlist.txt
Watch the slashes. aspell likes to see a slash in the name or it will search some default location.
BUGS
This program should be able to identify the language from the document (e.g., <book lang="de">), but aspell doesn't handle changing the
language on the fly.
