Interactive Perl client for ACEDB
Options (can be abbreviated):
-host <hostname> Server host (localhost)
-port <port> Server port (200005)
-path <db path> Local database path (no default)
-url <url> Server URL (see below
-login <user> Username
-pass <pass> Password
-tcsh Use T-shell completion mode
-save Save database updates automatically
-exec <command> Run a command and quit
Respects the environment variables \$ACEDB_HOST and \$ACEDB_PORT, if present.
You can edit the command line using the cursor keys and emacs style
key bindings. Use up and down arrows (or ^P, ^N) to access the history.
The tab key completes partial commands. In tcsh mode, the tab key cycles
among the completions, otherwise pressing the tab key a second time lists
all the possibilities.
You may use multiple -exec switches to run a sequence of commands, or
separate multiple commands in a single string by semicolons:
ace.pl -e 'find Author Thierry-Mieg*' -e 'show'
ace.pl -e 'find Author Thierry-Mieg*; show'
Server URLs:
rpcace://hostname:port RPC server
sace://hostname:port Socket server
tace:/path/to/database Local database
/path/to/database Local database
Usernames can be provided as sace://user\@hostname:port
