This program requires that the 'swish-e' full-text indexer be installed.
|
|
On Debian and Ubuntu systems, you may install it by running
|
|
sudo apt-get install swish-e
|
|
On Ubuntu systems, this requires that the "universe" repository be enabled.

$b: Search emc2 source code and documentation
|
|
|
|
Usage:
|
|
$b [-R] [-F file-re] swish-pattern [grep-pattern]
|
|
|
|
-R: Rebuild the index. This is equivalent to running 'make swish'
|
|
in the source directory
|
|
|
|
-F: Specify a subset of files to search. This is an extended regular
|
|
expression, not a shell glob. To search all ".c" files, use
|
|
$b -F '\.c$' ...
|
|
|
|
swish-pattern: Specify the pattern to pass to 'swish -w'. See
|
|
"man SWISH-RUN" for more information
|
|
|
|
grep-pattern: Specify the pattern to pass to 'grep'. Each file listed
|
|
by swish is grepped for this pattern, and matching lines are
|
|
printed. By default, $b attempts to turn swish-pattern into
|
|
a grep-pattern, but this only works if swish-pattern is a simple
|
|
word. For more information about grep patterns, see 'man grep'
