taggrep(1)

NAME

taggrep - Filter the contents of a tagged collection using a tag expression

SYNOPSIS

taggrep [options] <tag-expression> [file1 [file2 [...]]]

DESCRIPTION

taggrep is a commandline utility to filter the elements of a tagged collection.

A tagged collection is a set of items in which each item is associated with a set of zero or more tags, in no particular order.

taggrep reads a tagged collection and, like grep, prints only the lines that match or do not match a given expression. Like grep uses regular expression to match strings, taggrep uses tag expressions to match the set of tags associated to a given item.

For documentation on the format of tagged collections and tag expressions, please refer to the tagcoll(1) manpage.

OPTIONS

This program follows the usual GNU command line syntax, with long options starting with two dashes (`-').

Help options:

-h, -?, --help: print an help message and exit.

-V, --version: print the program version and exit.

Other options:

-v, --invert-match: invert the sense of matching, to select non-matching lines.

-q, --quiet: do not write anything to standard output, but exit with 0 if any match is found.

EXAMPLES

# Output the collection of all mail clients
taggrep 'mail && client' collection
# Output a collection without all elements marked with 'partially-tagged'
taggrep -v 'partially-tagged' collection
# Check if a collection contains mail clients and word processors
taggrep -q '(mail && client) || office::wordproc' collection-file && echo Yes
