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.
