cacheCleanup

Source: R/cacheCleanup.R
cacheCleanup.Rd

Delete files older than the specified number of days, based on file time metadata (per default atime = last access time).

Usage

cacheCleanup(
  daysThreshold,
  path = getConfig("cachefolder", verbose = FALSE),
  timeType = c("atime", "mtime", "ctime"),
  ask = TRUE,
  readlineFunction = readline
)

Arguments

daysThreshold

Files older than this many days are deleted/returned.

path

Path to where to look for old files.

timeType

Which file metadata time should be used. One of atime (last access time, default), mtime (last modify time), ctime (last metadata change).

ask

Whether to ask before deleting.

readlineFunction

Only needed for testing. A function to prompt the user for input.

Value

If the user answers 'n', a data.frame as returned by base::file.info, containing only files older than <daysThreshold> days.

Details

File time metadata is not available on all systems and the semantics are also system dependent, so please be careful and check that the correct files are deleted. This function will return a data.frame containing all files that would be deleted if the user answers 'n' to the question. If deleting files fails a warning is created.
