Hello!
I have a file with 4 columns. I am trying to have it sort first with respect to the first column, and then with respect to the number of counts (in descending count) in the second column within the same first column identity.
For example:
Input:

I want to sort lines by how many times a string occurs in each line (the most times first).
I know how to do this in two passes (add a count field in the first pass then sort on it in the second pass).
However, can it be done more optimally with a single AWK command? My AWK has improved... (11 Replies)

STRING(3) Library Functions Manual STRING(3)NAME
strcat, strncat, strcmp, strncmp, strcasecmp, strncasecmp, strcpy, strncpy, strlen, index, rindex - string operations
SYNOPSIS
#include <strings.h>
char *strcat(s, append)
char *s, *append;
char *strncat(s, append, count)
char *s, *append;
int count;
strcmp(s1, s2)
char *s1, *s2;
strncmp(s1, s2, count)
char *s1, *s2;
int count;
strcasecmp(s1, s2)
char *s1, *s2;
strncasecmp(s1, s2, count)
char *s1, *s2;
int count;
char *strcpy(to, from)
char *to, *from;
char *strncpy(to, from, count)
char *to, *from;
int count;
strlen(s)
char *s;
char *index(s, c)
char *s, c;
char *rindex(s, c)
char *s, c;
DESCRIPTION
These functions operate on null-terminated strings. They do not check for overflow of any receiving string.
Strcat appends a copy of string append to the end of string s. Strncat copies at most count characters. Both return a pointer to the null-
terminated result.
Strcmp compares its arguments and returns an integer greater than, equal to, or less than 0, according as s1 is lexicographically greater
than, equal to, or less than s2. Strncmp makes the same comparison but looks at at most count characters. Strcasecmp and strncasecmp are
identical in function, but are case insensitive. The returned lexicographic difference reflects a conversion to lower-case.
Strcpy copies string from to to, stopping after the null character has been moved. Strncpy copies exactly count characters, appending
nulls if from is less than count characters in length; the target may not be null-terminated if the length of from is count or more. Both
return to.
Strlen returns the number of non-null characters in s.
Index (rindex) returns a pointer to the first (last) occurrence of character c in string s or zero if c does not occur in the string. Set-
ting c to NULL works.
