Pattern

A pattern is basically the same as bash pattern matching, with the following extensions:

Pattern	Description
expr/	Matches any file or folder matched by expr and it's recursive contents
/expr	Matches expr only if it matches from the start
!<expr>	Negate expression. It's not possible to negate a negated expression.
<expr>	All other expressions match filenames.

Examples:

Pattern	bash pattern	Description
x	*/x|x	Match "x" anywhere
*.c	*/*.c|*.c	Match files with .c extension anywhere
/x	x	Match "x" only in the top folder
x/	*/x/*|x/*	Match anything below a folder named "x"
/x/	x/*	Match anything below a top folder named "x"

Here is a simple example to match .txt files that are stored somewhere inside the doc folder or subfolders. But it avoids those, that are in an "old" folder.

mkdir .mulle-monitor/etc/match.d
cat <<EOF > .mulle-monitor/etc/match.d/00-doc-all
/doc/*.txt
!old/
EOF
