In order to speed up its operations, CLEX internally caches the data about user and group accounts. This data is mainly used to obtain the file owners' names. It does not change very often.
The cache will be updated before reading contents of a directory, if:
/etc/passwd or /etc/group is detected, or
This means that if the account data is not stored in the standard system files, but e.g. in a
NIS network database, it could take few minutes before CLEX updates its cache.
To overcome this slight limitation you can press <esc> before ctrl-R
to force a refresh of the account data cache.
