vsi_unlink_batch {gdalraster}

Delete several files in a batch

Description

vsi_unlink_batch() deletes a list of files passed in a character vector. All files should belong to the same file system handler. This is implemented efficiently for /vsis3/ and /vsigs/ (provided for /vsigs/ that OAuth2 authentication is used). This function is a wrapper for VSIUnlinkBatch() in the GDAL Common Portability Library.

Usage

vsi_unlink_batch(filenames)

Arguments

filenames

Character vector. The list of files to delete.

Value

Logical vector of length(filenames) with values depending on the success of deletion of the corresponding file. NULL might be returned in case of a more general error (for example, files belonging to different file system handlers).

Examples

# regular file system for illustration
elev_file <- system.file("extdata/storml_elev.tif", package="gdalraster")
tcc_file <- system.file("extdata/storml_tcc.tif", package="gdalraster")

tmp_elev <- file.path(tempdir(), "tmp_elev.tif")
file.copy(elev_file,  tmp_elev)
tmp_tcc <- file.path(tempdir(), "tmp_tcc.tif")
file.copy(tcc_file,  tmp_tcc)
vsi_unlink_batch(c(tmp_elev, tmp_tcc))
