BASENAME(3) BSD Library Functions Manual BASENAME(3)NAME
basename -- extract the base portion of a pathname
SYNOPSIS
#include <libgen.h>
char *
basename(char *path);
DESCRIPTION
The basename() function returns the last component from the pathname pointed to by path, deleting any trailing '/' characters. If path con-
sists entirely of '/' characters, a pointer to the string "/" is returned. If path is a null pointer or the empty string, a pointer to the
string "." is returned.
RETURN VALUES
On successful completion, basename() returns a pointer to the last component of path.
If basename() fails, a null pointer is returned and the global variable errno is set to indicate the error.
ERRORS
The following error codes may be set in errno:
[ENAMETOOLONG] The path component to be returned was larger than MAXPATHLEN.
WARNINGS
The basename() function returns a pointer to internal static storage space that will be overwritten by subsequent calls. The function may
modify the string pointed to by path.
LEGACY SYNOPSIS
#include <libgen.h>
char *
basename(const char *path);
In legacy mode, path will not be changed.
SEE ALSO basename(1), dirname(1), dirname(3), compat(5)STANDARDS
The basename() function conforms to X/Open Portability Guide Issue 4, Version 2 (``XPG4.2'').
HISTORY
The basename() function first appeared in OpenBSD 2.2 and FreeBSD 4.2.

BASENAME(3) BSD Library Functions Manual BASENAME(3)NAME
basename -- extract the base portion of a pathname
SYNOPSIS
#include <libgen.h>
char *
basename(char *path);
char *
basename_r(const char *path, char *bname);
DESCRIPTION
The basename() function returns the last component from the pathname pointed to by path, deleting any trailing '/' characters. If path con-
sists entirely of '/' characters, a pointer to the string "/" is returned. If path is a null pointer or the empty string, a pointer to the
string "." is returned.
The basename_r() variation accepts a buffer of at least MAXPATHLEN bytes in which to store the resulting component.
IMPLEMENTATION NOTES
The basename() function returns a pointer to internal storage space allocated on the first call that will be overwritten by subsequent calls.
basename_r() is therefore preferred for threaded applications.
RETURN VALUES
On successful completion, basename() and basename_r() return pointers to the last component of path.
If they fail, a null pointer is returned and the global variable errno is set to indicate the error.
ERRORS
The following error codes may be set in errno:
[ENAMETOOLONG] The path component to be returned was larger than MAXPATHLEN.
SEE ALSO basename(1), dirname(1), dirname(3)STANDARDS
The basename() function conforms to X/Open Portability Guide Issue 4, Version 2 (``XPG4.2'').
HISTORY
The basename() function first appeared in OpenBSD 2.2 and FreeBSD 4.2. The basename_r() function first appeared in OS X 10.12.

CAVEATS
basename() returns a pointer to internal static storage space that will be overwritten by subsequent calls.
Other vendor implementations of basename() may modify the contents of the string passed to basename(); this should be taken into account when
writing code which calls this function if portability is desired.

Hi there,
Is there any way to obtain a real path from a weird path. For example :
/foo/../bar/ -> /bar/
/foo/. -> /foo/
Thanks in advance

Hi
I have been able generate a file ($ELOG) that can have multiple lines within it. The first column represents the full path source file and the other is the full path target ... the file names are the same but the target directory paths are slightly different.
