As for comparing two strings of known lengths, that's what strncmp is for.
Code:
char *string1="abcdefg";
char *string2="abcdqwerty";
if(strncmp(string1, string2, 4) == 0)
{
printf("The first four characters of these strings are the same\n");
}
I have file A with 10 lines and file B with 15 lines
I have to read each line from file A and match it with lines in file B
If matching lines are found i need to delete it from file B
The ouput will be the deleted file B
I tried the following in the loop but the deleting part is not... (5 Replies)

Hi there,
I have two input files. I need to match the last two columns of each line in File1 with the first two columns of a line in File2. Example:
File1

CCC DD 356 643
File2
766 332 12
234 789 64
122 633 23
426 624 88
777 453 22

Hi,
I want to achieve something similar to what described in another post:
The difference is I want to add the line if the pattern is not found.

Hello,
I have two files file 1 and file 2 each having result of a query on certain database tables and need to compare for Col1 in file1 with Col3 in file2, compare Col2 with Col4 and output the value of Col1 from File1 which is a) not present in Col3 of File2 b) value of Col2 is different from...

The awk below produces the current output, which will add +1 to $3. However, I am trying to add the length of the matching characters between $5 and $6 to $3. I have tried using sub as a variable to store the length but am not able to do so correctly. I added comments to each line and the... (4 Replies)
In the awk below I am trying to cp and paste each matching line in f2 to $3 in f1 if $2 of f1 is in the line in f2 somewhere. There will always be a match (usually more then 1) and my actual data is much larger (several hundreds of lines) in both f1 and f2. When the line in f2 is pasted to $3 in... (4 Replies)

strncmp
strcmp(9F) Kernel Functions for Drivers strcmp(9F)NAME
strcmp, strcasecmp, strncasecmp, strncmp - compare two null-terminated strings.
SYNOPSIS
#include <sys/ddi.h>
int strcmp(const char *s1, const char *s2);
int strcasecmp(const char *s1, const char *s2);
int strncasecmp(const char *s1, const char *s2, size_t n);
int strncmp(const char *s1, const char *s2, size_t n);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI).
PARAMETERS
s1, s2 Pointers to character strings.
n Count of characters to be compared.
DESCRIPTION
strcmp()
strcmp() returns 0 if the strings are the same, or the integer value of the expression (*s1 - *s2) for the last characters compared if
they differ.
strcasecmp(), strncasecmp()
The strcasecmp() and strncasecmp() functions are case-insensitive versions of strcmp() and strncmp(), respectively, described in this sec-
tion. They assume the ASCII character set and ignore differences in case when comparing lowercase and uppercase characters.
strncmp()
strncmp() returns 0 if the first n characters of s1 and s2 are the same, or (*s1 - *s2) for the last characters compared if they dif-
fer.
RETURN VALUES
strcmp() returns 0 if the strings are the same, or (*s1 - *s2) for the last characters compared if they differ.
strcasecmp() and strncasecmp() return values in the same fashion as strcmp() and strncmp(), respectively.
strncmp() returns 0 if the first n characters of strings are the same, or (*s1 - *s2) for the last characters compared if they differ.
CONTEXT
These functions can be called from user or interrupt context.
