I appoligize, I meant using a regular expression so,using a regex expression, how can I extract just the first 5-7 digits of a string(anywhere in the string)and end there? So in this case I only want to print out only the "first" set of 5-7 digits of a string which would give me an output of:
Code:
145148
1451486
1451489
45148

I'm curious, how would I set validation on a field size to make sure it only ever accepts a 6 digit number?
I currently have validation for it to be an integer in place but can't find anywhere that says how to make it only a length of 6 digits.

re_exec
RE_COMP(3) BSD Library Functions Manual RE_COMP(3)NAME
re_comp, re_exec -- regular expression handler
LIBRARY
Compatibility Library (libcompat, -lcompat)
SYNOPSIS
#include <re_comp.h>
char *
re_comp(const char *s);
int
re_exec(const char *s);
DESCRIPTION
This interface is made obsolete by regex(3). It is available from the compatibility library, libcompat.
The re_comp() function compiles a string into an internal form suitable for pattern matching. The re_exec() function checks the argument
string against the last string passed to re_comp().
The re_comp() function returns 0 if the string s was compiled successfully; otherwise a string containing an error message is returned. If
re_comp() is passed 0 or a null string, it returns without changing the currently compiled regular expression.
The re_exec() function returns 1 if the string s matches the last compiled regular expression, 0 if the string s failed to match the last
compiled regular expression, and -1 if the compiled regular expression was invalid (indicating an internal error).
The strings passed to both re_comp() and re_exec() may have trailing or embedded newline characters; they are terminated by NULs. The regu-
lar expressions recognized are described in the manual entry for ed(1), given the above difference.
DIAGNOSTICS
The re_exec() function returns -1 for an internal error.
The re_comp() function returns one of the following strings if an error occurs:
No previous regular expression,
Regular expression too long,
unmatched (,
missing ],
too many () pairs,
unmatched ).
SEE ALSO ed(1), egrep(1), ex(1), fgrep(1), grep(1), regex(3)HISTORY
The re_comp() and re_exec() functions appeared in 4.0BSD.
