- The iid program is an interactive shell on top of the mkid, lid, aid
- database programs. It allows interactive queries of an ID database in
- a fashion similar to a DIALOG session. Iid remembers the sets of files
- that were reported by any lid or aid request. These sets are refered
- to by set numbers. The commands available are:
-
- BEGIN <directory> cd to directory (presumably containing an ID file).
- B short for BEGIN
- SS <query> run query displaying the sets generated
- FILES <query> run query listing the files in the final set
- F short for FILES
- SHOW <set number> run pager program on files in set
- P short for SHOW
- SETS show currently defined sets
- HELP run pager on this file
- ? or H short commands for HELP
- OFF exit iid
- <cmd> run a shell command as a file name query
- !<cmd> run a shell command
-
- A <set number> is the letter 's' (or 'S') followed (with no space) by
- a number. Set numbers may be used as terms in a query.
-
- A <query> is:
- <set number>
- <identifier>
- lid <identifier list>
- aid <identifier list>
- match <wild card list>
- <query> or <query>
- <query> and <query>
-
- The words "lid", "aid", "match", "or", and "and" are keywords, along
- with any word that looks like a set number. If you have to use one of
- these (or in arguments to lid, aid or match, shell escape characters)
- then quote the name.
-
- The "match" operator constructs a set of files by running the "pid"
- program with the wild card pattern as an argument. This is the only
- operator which constructs sets based on file names rather than
- contents.
-
- An identifier by itself is simply shorthand for "lid identifier". (If
- the -a option was used to invoke iid, then a simple identifier is
- shorthand for "aid identifier").
-
- Example run:
-
- ===> iid
- ===> ss lid "^get" or lid "Arg$"
- S0 14 lid -kmn "^get"
- S1 3 lid -kmn "Arg$"
- S2 15 (lid -kmn "^get") OR (lid -kmn "Arg$")
- ===> f s1
- lid.c
- paths.c
- init.c
- ===> ls *.c
- S3 28 ls *.c
- ===> ls s*
- S4 9 ls s*
- ===> ss s3 and s4
- S5 4 (ls *.c) AND (ls s*)
- ===> !grep vhil s5
- scan-c.c: setCArgs("vhil",'+',"v");
- scan-c.c: setCArgs("vhil",'+',"v");
- ===> off
-
- In this example the 'ss' command displays the sets it creats as it
- does the parts of the query. In this case 3 sets are created, set S0
- has 14 files in it, set S1 has 3 files and the union of the two sets,
- S2, has 15 files. A description of the query that created any given
- set is kept along with the set and displayed when sets are printed.
-
- The 'f s1' command says list the files in set S1, and the three files
- in the set are displayed.
-
- The 'ls' commands are examples of using arbitrary shell commands to
- generate lists of files. In this case the 'ls' command. (This could
- have been done as part of another query using the 'match' operator).
-
- The '!grep vhil s5' command runs the 'grep' shell command passing as
- arguments 'vhil' and the names of all the files in s5.
-
- The 'off' command terminated the example session.
-
- Keywords, commands, and set numbers are recognized regardless of case
- (and is And is aNd). Other parameters are case sensitive.
-
- The iid program can also be run in a batch mode using the -c option.
- For more information on command line options, run "iid -H", or use the
- Unix 'man' command.
