Thanks for the reply! I don't clearly understand the code you've provided me. In fact I'm a bit confused . Is there any other way to append the line numbers other than what I think I'm seeing (dynamic allocation)?

Does the code you've provided store a linked list of line numbers (integers)? I'm trying to print out one inputted word and the line number found and it's giving me '0' for the line number. Line number is originally set to '1' in the program.

Hi all,
Think this is a pretty simple problem, but I've been thinking about it for a few days. Let's say that I'm going to have to output the contents of a file as the body of a mailx message.
I'll probably do this: cat <filename> | mailx <extra commands>
However, how do I go about doing... (1 Reply)
Hi,
Well as the title says, I have an array of strings (delimited by null). The length of the array is variable and length of each string is variable as well. What I need is one huge string with the original strings in the array separated by spaces.
For example is an array is such that array... (12 Replies)

Hello,
I'm trying to run a program on a directory (traverse sub dirs too) through my csh script. Arrays support in CSH is appalling, something like associative arrays would have helped me do this so much easier.
Anyway, I want to hold some details extracted from the program and then at the... (0 Replies)
I have these
str1=$(echo "This is string one with spaces \n This is also my sentence 1")
When I echo $str1, it displays the new line character properly.
Now I have another new variable say str2.
I want to concatenate in this way.. str1 + newline character + and then str2.
That's I... (3 Replies)

lex
LEX(1) General Commands Manual LEX(1)NAME
lex - generator of lexical analysis programs
SYNOPSIS
lex [ -tvfn ] [ file ] ...
DESCRIPTION
Lex generates programs to be used in simple lexical analyis of text. The input files (standard input default) contain regular expressions
to be searched for, and actions written in C to be executed when expressions are found.
A C source program, 'lex.yy.c' is generated, to be compiled thus:
cc lex.yy.c -ll
This program, when run, copies unrecognized portions of the input to the output, and executes the associated C action for each regular
expression that is recognized.
The options have the following meanings.
-t Place the result on the standard output instead of in file "lex.yy.c".
-v Print a one-line summary of statistics of the generated analyzer.
-n Opposite of -v; -n is default.
-f "Faster" compilation: don't bother to pack the resulting tables; limited to small programs.
EXAMPLE
lex lexcommands
would draw lex instructions from the file lexcommands, and place the output in lex.yy.c
%%
[A-Z] putchar(yytext[0]+'a'-'A');
[ ]+$ ;
[ ]+ putchar(' ');
is an example of a lex program that would be put into a lex command file. This program converts upper case to lower, removes blanks at the
end of lines, and replaces multiple blanks by single blanks.
