It is equivalent to doing: gsutil cp url... - (The final '-' causes gsutil to stream the output to stdout.) <B>WARNING: DATA INTEGRITY CHECKING NOT DONE</B> The gsutil cat command does not compute a checksum of the downloaded data. Therefore, we recommend that users either perform their own validation of the output of gsutil cat or use gsutil cp or rsync (both of which perform integrity checking automatically). <B>OPTIONS</B> -h Prints short header for each object. For example: gsutil cat -h gs://bucket/meeting_notes/2012_Feb/*.txt This would print a header with the object name before the contents of each text object that matched the wildcard. -r range Causes gsutil to output just the specified byte range of the object. Ranges are can be of these forms: start-end (e.g., -r 256-5939) start- (e.g., -r 256-) -numbytes (e.g., -r -5) where offsets start at 0, start-end means to return bytes start through end (inclusive), start- means to return bytes start through the end of the object, and -numbytes means to return the last numbytes of the object. For example: gsutil cat -r 256-939 gs://bucket/object returns bytes 256 through 939, while: gsutil cat -r -5 gs://bucket/object returns the final 5 bytes of the object.

The Modula-2 lexer supports several dialects. By default, it operates in fallback mode, recognising the *combined* literals, punctuation symbols and operators of all supported dialects, and the *combined* reserved words and builtins of PIM Modula-2, ISO Modula-2 and Modula-2 R10, while not differentiating between library defined identifiers. To select a specific dialect, a dialect option may be passed or a dialect tag may be embedded into a source file. Dialect Options: `m2pim` Select PIM Modula-2 dialect. `m2iso` Select ISO Modula-2 dialect. `m2r10` Select Modula-2 R10 dialect. `objm2` Select Objective Modula-2 dialect. The PIM and ISO dialect options may be qualified with a language extension. Language Extensions: `+aglet` Select Aglet Modula-2 extensions, available with m2iso. `+gm2` Select GNU Modula-2 extensions, available with m2pim. `+p1` Select p1 Modula-2 extensions, available with m2iso. `+xds` Select XDS Modula-2 extensions, available with m2iso. Passing a Dialect Option via Unix Commandline Interface Dialect options may be passed to the lexer using the `dialect` key. Only one such option should be passed. If multiple dialect options are passed, the first valid option is used, any subsequent options are ignored. Examples: `$ pygmentize -O full,dialect=m2iso -f html -o /path/to/output /path/to/input` Use ISO dialect to render input to HTML output `$ pygmentize -O full,dialect=m2iso+p1 -f rtf -o /path/to/output /path/to/input` Use ISO dialect with p1 extensions to render input to RTF output Embedding a Dialect Option within a source file A dialect option may be embedded in a source file in form of a dialect tag, a specially formatted comment that specifies a dialect option. Dialect Tag EBNF:: dialectTag : OpeningCommentDelim Prefix dialectOption ClosingCommentDelim ; dialectOption : 'm2pim' | 'm2iso' | 'm2r10' | 'objm2' | 'm2iso+aglet' | 'm2pim+gm2' | 'm2iso+p1' | 'm2iso+xds' ; Prefix : '!' ; OpeningCommentDelim : '(*' ; ClosingCommentDelim : '*)' ; No whitespace is permitted between the tokens of a dialect tag. In the event that a source file contains multiple dialect tags, the first tag that contains a valid dialect option will be used and any subsequent dialect tags will be ignored. Ideally, a dialect tag should be placed at the beginning of a source file. An embedded dialect tag overrides a dialect option set via command line. Examples: ``(*!m2r10*) DEFINITION MODULE Foobar; ...`` Use Modula2 R10 dialect to render this source file. ``(*!m2pim+gm2*) DEFINITION MODULE Bazbam; ...`` Use PIM dialect with GNU extensions to render this source file. Algol Publication Mode: In Algol publication mode, source text is rendered for publication of algorithms in scientific papers and academic texts, following the format of the Revised Algol-60 Language Report. It is activated by passing one of two corresponding styles as an option: `algol` render reserved words lowercase underline boldface and builtins lowercase boldface italic `algol_nu` render reserved words lowercase boldface (no underlining) and builtins lowercase boldface italic The lexer automatically performs the required lowercase conversion when this mode is activated. Example: ``$ pygmentize -O full,style=algol -f latex -o /path/to/output /path/to/input`` Render input file in Algol publication mode to LaTeX output. Rendering Mode of First Class ADT Identifiers: The rendering of standard library first class ADT identifiers is controlled by option flag "treat_stdlib_adts_as_builtins". When this option is turned on, standard library ADT identifiers are rendered as builtins. When it is turned off, they are rendered as ordinary library identifiers. `treat_stdlib_adts_as_builtins` (default: On) The option is useful for dialects that support ADTs as first class objects and provide ADTs in the standard library that would otherwise be built-in. At present, only Modula-2 R10 supports library ADTs as first class objects and therefore, no ADT identifiers are defined for any other dialects. Example: ``$ pygmentize -O full,dialect=m2r10,treat_stdlib_adts_as_builtins=Off ...`` Render standard library ADTs as ordinary library types. .. versionadded:: 1.3 .. versionchanged:: 2.1 Added multi-dialect support.
