The dcachedel program
dcachedel - dcachedel - delete records from a cache file.
SYNOPSIS
dcachedel [OPTIONS] CACHE KEY
DESCRIPTION
dcachedel by default deletes the first record found by a search for KEY in CACHE.
OPTIONS
-
-a, --all
-
Delete all records with the same key.
The default is to delete the first record
found.
-
-n, --record-number=NUMBER
-
Delete the n'th record with the key.
-
-N, --no-sync
-
Do not fsync cache to disk.
The default is to call fsync, which waits until the data has been written to disk. This is costly but safe. Using this option allows the operating system to schedule the writting to a later time, thus making it impossible to detect any error due to, for example, a bad hard disk.
The use of this option is not recommended unless speed is more important than correctness. Note that fsync costs about 5 to 10 percent of a second.
-
-T, --transaction
-
Delete entries in one transaction.
The default is to do one operation after each other. With
this option all changes will be done at once, ensuring that
the cache either contains the old or the new state.
Note: this costs memory and disk-space.
-
--see-also
-
Where to find related information.
-
--examples
-
Usage examples.
-
--version

of that option, without an argument it will list
all options.
-
--longhelp
-
