DESCRIPTION
Greple's -Mselect module allows to filter files using their name and content data. It is usually supposed to be used along with -Mfind or -Mdig module.
For example, next command scan files end with .pl
and .pm
under current directory.
greple -Mdig -Mselect --suffix=pl,pm foobar --dig .
This is almost equivalent to the next command using --dig option with extra conditional expression for find command.
greple -Mdig foobar --dig . -name '*.p[lm]'
The problems is that the above command does not search perl command script without suffixes. Next command looks for both files looking at #!
(shebang) line.
greple -Mdig -Mselect --suffix=pl,pm --shebang perl foobar --dig .
Generic option --select-name, --select-path and --select-data take regular expression and works for arbitrary use.
ORDER and DEFAULT
Besides normal inclusive rules, there is exclusive rules which start with --x- option name.
As for the order of rules, all exclusive rules are checked first, then inclusive rules are applied.
When no rules are matched, default action is taken. If no inclusive rule exists, it is selected. Otherwise discarded.
