That's a wildcard, not a regular expression ("?" stands for a single character).
Some implementations of "find" support "regex" and "iregex" flags.

Hi,
Could anybody explain why will evaluate to true for a string that is not null, not empty string, and has at least one non-space char?
My understanding is that ^ means exclude all chars inside . So I thought it should mean anything except space.
This seems a big mystery to me. (9 Replies)

re_exec
RE_COMP(3) Linux Programmer's Manual RE_COMP(3)
NAME
re_comp, re_exec - BSD regex functions
SYNOPSIS
#define _REGEX_RE_COMP
#include <sys/types.h>
#include <regex.h>
char *re_comp(char *regex);
int re_exec(char *string);
DESCRIPTION
re_comp() is used to compile the null-terminated regular expression pointed to by regex. The compiled pattern occupies a static area, the
pattern buffer, which is overwritten by subsequent use of re_comp(). If regex is NULL, no operation is performed and the pattern buffer's
contents are not altered.
re_exec() is used to assess whether the null-terminated string pointed to by string matches the previously compiled regex.
RETURN VALUE
re_comp() returns NULL on successful compilation of regex otherwise it returns a pointer to an appropriate error message.
re_exec() returns 1 for a successful match, zero for failure.
ATTRIBUTES
Multithreading (see pthreads(7))
The re_comp() and re_exec() functions are not thread-safe.
CONFORMING TO
4.3BSD.
NOTES
These functions are obsolete; the functions documented in regcomp(3) should be used instead.
