I would like to extract the first portion of filename from a list of files.
The filename pattern is of the form 123456789_TEXT_TEXT_TEXT_.csv. I want to extract just the numerical portion of this filename from the list of files and then output this into another text file.

dirname
BASENAME(3) Linux Programmer's Manual BASENAME(3)
NAME
basename, dirname - parse pathname components
SYNOPSIS
#include <libgen.h>
char *dirname(char *path);
char *basename(char *path);
DESCRIPTION
Warning: there are two different functions basename() - see below.
The functions dirname() and basename() break a null-terminated pathname string into directory and filename components. In the usual case,
dirname() returns the string up to, but not including, the final '/', and basename() returns the component following the final '/'. Trail-
ing '/' characters are not counted as part of the pathname.
If path does not contain a slash, dirname() returns the string "." while basename() returns a copy of path. If path is the string "/",
then both dirname() and basename() return the string "/". If path is a NULL pointer or points to an empty string, then both dirname() and
basename() return the string ".".
Concatenating the string returned by dirname(), a "/", and the string returned by basename() yields a complete pathname.
Both dirname() and basename() may modify the contents of path, so it may be desirable to pass a copy when calling one of these functions.
These functions may return pointers to statically allocated memory which may be overwritten by subsequent calls. Alternatively, they may
return a pointer to some part of path, so that the string referred to by path should not be modified or freed until the pointer returned by
the function is no longer required.
The following list of examples (taken from SUSv2) shows the strings returned by dirname() and basename() for different paths:
path dirname basename
/usr/lib /usr lib
/usr/ / usr
usr . usr
/ / /
. . .
.. . ..
RETURN VALUE
Both dirname() and basename() return pointers to null-terminated strings. (Do not pass these pointers to free(3).)
CONFORMING TO
POSIX.1-2001.
NOTES
There are two different versions of basename() - the POSIX version described above, and the GNU version, which one gets after
#define _GNU_SOURCE /* See feature_test_macros(7) */
#include <string.h>
The GNU version never modifies its argument, and returns the empty string when path has a trailing slash, and in particular also when it is
"/". There is no GNU version of dirname().
With glibc, one gets the POSIX version of basename() when <libgen.h> is included, and the GNU version otherwise.
BUGS
In the glibc implementation of the POSIX versions of these functions they modify their argument, and segfault when called with a static
string like "/usr/". Before glibc 2.2.1, the glibc version of dirname() did not correctly handle pathnames with trailing '/' characters,
and generated a segfault if given a NULL argument.
EXAMPLE
char *dirc, *basec, *bname, *dname;
char *path = "/etc/passwd";
dirc = strdup(path);
basec = strdup(path);
dname = dirname(dirc);
bname = basename(basec);
printf("dirname=%s, basename=%s
", dname, bname);
