checkgroups - update group descriptions


checkgroups checkgroupsfile


Leafnode is a USENET package intended for small sites, where there are few users and little disk space, but where a large number of groups is desired.

Checkgroups is the program which parses checkgroup scripts to include new/updated group descriptions into the active file (which is usually /var/spool/news/leaf.node/groupinfo).

Checkgroups sets its real and effective uid to "news".


is a file which contains the newsgroup name and the description on one line, separated by whitespace. Checkgroups scripts are sometimes sent out by news administrators (e.g. in the bionet.* hierarchy).


This variable is parsed as an unsigned integer value and determines how many seconds checkgroups will wait when trying to obtain the lock file from another leafnode program. 0 means to wait indefinitely. This variable takes precedence over the configuration file.
