PARSEFILENAME Procedure

Reference Guide > P Routines > PARSEFILENAME Procedure

Extracts specified parts of a full file pathname.

Usage

PARSEFILENAME, pathname

Input Parameters

pathname — A string containing a full file pathname.

Keywords

Extension — If set, returns the filename extension (for example, .pro).

Filename — If set, returns a string containing the file root name with its extension (for example, boulder.img).

Fileroot — If set, returns a string containing the filename without its extension.

Path — If set, returns a string containing the full pathname without the filename.

Separator — If set, specifies a single-char string to use as a directory separator. The default separator is platform-specific:

(UNIX) '/'

(WIN) '\'

Discussion

The PARSEFILENAME procedure takes a string containing a path and/or a filename and returns its constituent components (path, filename, file root, and extension) in variables specified using the keywords.

For example, on a UNIX system the file file_mine.pro consists of the file root file_mine and the extension pro.

Example

The following example demonstrates PARSEFILENAME with a UNIX pathname:

full = '/home/work/data/testimage.tif'

PARSEFILENAME, full, Fileroot=root, $

   Path=path, Filename=name, Extension=extension

INFO, path, root, name, extension

; PV-WAVE prints the following:

; PATH        STRING    = '/home/work/data/'

; ROOT        STRING    = 'testimage'

; NAME        STRING    = 'testimage.tif'

; EXTENSION   STRING    = 'tif'
