Is there an option or a way with the split command to rename the partitioned files with a counter. For example, can the files testaa, testab, testac be renamed to test1, test2, test3 from the split command without explicilty renaming files.
Thanks,

pathbuf
PATHBUF(9) BSD Kernel Developer's Manual PATHBUF(9)NAME
pathbuf, pathbuf_create, pathbuf_assimilate, pathbuf_copyin, pathbuf_destroy -- path buffer abstraction
SYNOPSIS
#include <sys/namei.h>
struct pathbuf *
pathbuf_create(const char *path);
struct pathbuf *
pathbuf_assimilate(char *pnbuf);
int
pathbuf_copyin(const char *userpath, struct pathbuf **ret);
void
pathbuf_destroy(struct pathbuf *path);
DESCRIPTION
The pathbuf interface is used to carry around pathnames. This helps simplify the namei(9) interface. A pathbuf should be thought of as a
path name string combined with whatever flags and metadata are needed to interpret it correctly. It is an abstract type; the internals are
hidden within the namei(9) implementation.
The pathbuf_create() function allocates and initializes a new pathbuf containing a copy of the path string path, which should be a kernel
pointer. The return value should be checked for being NULL in case the system is out of memory. Passing a path name larger than PATH_MAX
will cause an assertion failure.
The pathbuf_copyin() function allocates and initializes a new pathbuf containing a path string copied from user space with copyinstr(9). It
returns an error code.
The pathbuf_assimilate() function creates a pathbuf using the string buffer provided as pnbuf. This buffer must be of size PATH_MAX and must
have been allocated with PNBUF_GET(). The buffer is ``taken over'' by the returned pathbuf and will be released when the pathbuf is
destroyed. Note: to avoid confusion and pointer bugs, pathbuf_assimilate() should only be used where absolutely necessary; e.g. the NFS
server code uses it to generate pathbufs from strings fetched from mbufs.
The pathbuf_destroy() function deallocates a pathbuf. Caution: because calling namei(9) loads pointers to memory belonging to the pathbuf
into the nameidata structure, a pathbuf should only be destroyed by the namei() caller once all manipulations of the nameidata are complete.
Also note that calling namei() destroys the contents of the pathbuf. Do not reuse a pathbuf for a second call to namei().
CODE REFERENCES
The pathbuf code is part of the name lookup code in sys/kern/vfs_lookup.c.
SEE ALSO namei(9)BUGS
There are cases where it is necessary to get the path string left behind after namei() has run. This produces an effect similar to
realpath(3). The interface for doing this is, for the time being, intentionally undocumented and subject to change.
