NAME
bk regex − demo program to show regular expressions in BitKeeper

SYNOPSIS
bk regex regex string [string ...]

DESCRIPTION
Some commands, most notably bk grep, can take a regular expression as an argument. This man page describes the BitKeeper version of regular expressions. This command may be used to match a regex against one or more strings to see examples of how the regular expression matching works.

Regular expressions are used to search text for approximate (or exact) matches. Knowing how regular expressions work can be useful, they are quite powerful. Suppose that the words “foo,” “bar,” and “blech” were considered inappropriate in your source tree; the following command would find all files which contain any of those words:

bk -U grep ’foo|bar|blech’

BitKeeper is compatible with the PERL regular expression syntax. For a quick start on PCRE, please see bk-pcre
