I am trying to get better at UNIX, and I wanted to post a question so I can take some advice from more experienced programmers. What are some things that you wished you knew (while you were learning UNIX) that you think every beginner should know? (2 Replies)
how do i implement a script that asks user to input a word. it should ask for input a word continuously until the word is longer than 5 characters then stop.
this is what i have so far

echo "continue"

Hi my name is Jenny.
I'm a very very big beginner with UNIX.
I've made Forms on my website, but need to add CGI to compliment them.
Presently, I don't have a host that supports UNIX.
Is there anywhere I can connect to a UNIX session for free?
If so, will they most likely have the latest... (2 Replies)
STRSPLIT(3pub) C Programmer's Manual STRSPLIT(3pub)NAME
strsplit - split string into words
SYNOPSIS
#include <publib.h>
int strsplit(char *src, char **words, int maxw, const char *sep);
DESCRIPTION
strsplit splits the src string into words separated by one or more of the characters in sep (or by whitespace characters, as specified by
isspace(3), if sep is the empty string). Pointers to the words are stored in successive elements in the array pointed to by words. No
more than maxw pointers are stored. The input string is modifed by replacing the separator character following a word with ' '. However,
if there are more than maxw words, only maxw-1 words will be returned, and the maxwth pointer in the array will point to the rest of the
string. If maxw is 0, no modification is done. This can be used for counting how many words there are, e.g., so that space for the word
pointer table can be allocated dynamically.
strsplit splits the src string into words separated by one or more of the characters in sep (or by whitespace characters, as defined by
isspace(3), if sep is the empty string). The src string is modified by replacing the separator character after each word with ' '. A
pointer to each word is stored into successive elements of the array words. If there are more than maxw words, a ' ' is stored after the
first maxw-1 words only, and the words[maxw-1] will contain a pointer to the rest of the string after the word in words[maxw-2].
RETURN VALUE
strsplit returns the total number of words in the input string.
EXAMPLE
Assuming that words are separated by white space, to count the number of words on a line, one might say the following.
n = strsplit(line, NULL, 0, "");
To print out the fields of a colon-separated list (such as PATH, or a
line from /etc/passwd or /etc/group), one might do the following.
char *fields[15];
int i, n;
n = strsplit(list, fields, 15, ":");
if (n > 15)
n = 15;
for (i = 0; i < n; ++i)
printf("field %d: %s
", i, fields[i]);
In real life, one would of course prefer to not restrict the number of
fields, so one might either allocated the pointer table dynamically
(first counting the number of words using something like the first
example), or realize that since it is the original string that is
being modified, one can do the following:
char *fields[15];
int i, n;
do {
n = strsplit(list, fields, 15, ":");
if (n > 15)
n = 15;
for (i = 0; i < n; ++i)
printf("field %d: %s
", i, fields[i]);
list = field[n-1] + strlen(field[n-1]);
} while (n == 15);

The idea for this function came from C-News source code by Henry Spencer and Geoff Collyer. Their function is very similar, but this
implementation is by Lars Wirzenius (lars.wirzenius@helsinki.fi)
