NAME

       cif-grep - A tool like grep to print fields in mmCIF files that match patterns

SYNOPSIS

       cif-grep [OPTION] pattern file1 [file2..]

DESCRIPTION

       This tool tries to work in a similar way as grep by searching mmCIF files comparing the
       content of fields to patterns.

OPTIONS

       Multiple files can be specified to search. If a directory name if specified, all files in
       that directory will be searched. Use the --recursive flag to do a recursive search.

       --item=<item>, -i <item>
              Limit the search to only the item specified in <item>. Default is to search all
              items. Item should be of the form '_category.item' with the leading underscore.

       --quiet, -q
              Print only the file names that match the pattern.

       --count, -c
              Only show the number of hits.

       --invert-match, -v
              Only select the fields that do not match the pattern.

       --line-number, -n
              Print the line numbers.

       --no-filename, -h
              Do not print the filename.

       --with-filename, -H
              Do print the filename.

       --files-with-matches, -l
              Print only the names of the files containing matches.

       --recursive, -r
              Search recursively.

       --verbose,-V
              Be more verbose, useful to diagnose validation errors.
