this removes all DESCRIPTION and COMMENT tags in a set +of FLAC files, and uses the \[en]preserve-modtime global option to keep +the FLAC file modification times the same (usually when files are edited +the modification time is set to the current time): +.PP +\f[C]metaflac --preserve-modtime --remove-tag=DESCRIPTION --remove-tag=COMMENT file1.flac file2.flac file3.flac\f[R] +.SH OPTIONS +.TP +\f[B]--preserve-modtime\f[R] +Preserve the original modification time in spite of edits. +.TP +\f[B]--with-filename\f[R] +Prefix each output line with the FLAC file name (the default if more +than one FLAC file is specified). +This option has no effect for options exporting to a file, like +\[en]export-tags-to. +.TP +\f[B]--no-filename\f[R] +Do not prefix each output line with the FLAC file name (the default if +only one FLAC file is specified). +.TP +\f[B]--no-utf8-convert\f[R] +Do not convert tags from UTF-8 to local charset, or vice versa. +This is useful for scripts, and setting tags in situations where the +locale is wrong. +.TP +\f[B]--dont-use-padding\f[R] +By default metaflac tries to use padding where possible to avoid +rewriting the entire file if the metadata size changes. +Use this option to tell metaflac to not take advantage of padding this +way. +.SH SHORTHAND OPERATIONS +.TP +\f[B]--show-md5sum\f[R] +Show the MD5 signature from the STREAMINFO block. +.TP +\f[B]--show-min-blocksize\f[R] +Show the minimum block size from the STREAMINFO block. +.TP +\f[B]--show-max-blocksize\f[R] +Show the maximum block size from the STREAMINFO block. +.TP +\f[B]--show-min-framesize\f[R] +Show the minimum frame size from the STREAMINFO block. +.TP +\f[B]--show-max-framesize\f[R] +Show the maximum frame size from the STREAMINFO block. +.TP +\f[B]--show-sample-rate\f[R] +Show the sample rate from the STREAMINFO block. +.TP +\f[B]--show-channels\f[R] +Show the number of channels from the STREAMINFO block. +.TP +\f[B]--show-bps\f[R] +Show the # of bits per sample from the STREAMINFO block. +.TP +\f[B]--show-total-samples\f[R] +Show the total # of samples from the STREAMINFO block. +.TP +\f[B]--show-vendor-tag\f[R] +Show the vendor string from the VORBIS_COMMENT block. +.TP +\f[B]--show-tag=name\f[R] +Show all tags where the field name matches `name'. +.TP +\f[B]--show-all-tags\f[R] +Show all tags. +This is an alias for \[en]export-tags-to=-. +.TP +\f[B]--remove-tag=name\f[R] +Remove all tags whose field name is `name'. +.TP +\f[B]--remove-first-tag=name\f[R] +Remove first tag whose field name is `name'. +.TP +\f[B]--remove-all-tags\f[R] +Remove all tags, leaving only the vendor string. +.TP +\f[B]--remove-all-tags-except=NAME1[=NAME2[=\&...]]\f[R] +Remove all tags, except the vendor string and the tag names specified. +Tag names must be separated by an = character. +.TP +\f[B]--set-tag=field\f[R] +Add a tag. +The field must comply with the Vorbis comment spec, of the form +\[lq]NAME=VALUE\[rq]. +If there is currently no tag block, one will be created. +.TP +\f[B]--set-tag-from-file=field\f[R] +Like --set-tag, except the VALUE is a filename whose contents will be +read verbatim to set the tag value. +Unless --no-utf8-convert is specified, the contents will be converted to +UTF-8 from the local charset. +This can be used to store a cuesheet in a tag (e.g. +--set-tag-from-file=\[lq]CUESHEET=image.cue\[rq]). +Do not try to store binary data in tag fields!

it can be, for example, 9.5, meaning a seekpoint +every 9.5 seconds). +If no SEEKTABLE block exists, one will be created. +If one already exists, points will be added to the existing table, and +any duplicates will be turned into placeholder points. +You may use many --add-seekpoint options; the resulting SEEKTABLE will +be the unique-ified union of all such values. +Example: --add-seekpoint=100x --add-seekpoint=3.5s will add 100 evenly +spaced seekpoints and a seekpoint every 3.5 seconds. +.TP +\f[B]--add-padding=length\f[R] +Add a padding block of the given length (in bytes). +The overall length of the new block will be 4 + length; the extra 4 +bytes is for the metadata block header. +.SH MAJOR OPERATIONS +.TP +\f[B]--list\f[R] +List the contents of one or more metadata blocks to stdout. +By default, all metadata blocks are listed in text format. +Use the options \f[B]--block-number\f[R], \f[B]--block-type\f[R] or +\f[B]--except-block-type\f[R] to change this behavior. +.TP +\f[B]--remove\f[R] +Remove one or more metadata blocks from the metadata. +Use the options \f[B]--block-number\f[R], \f[B]--block-type\f[R] or +\f[B]--except-block-type\f[R] to specify which blocks should be removed. +Note that if both --block-number and --[except-]block-type are +specified, the result is the logical AND of both arguments. +Unless --dont-use-padding is specified, the blocks will be replaced with +padding. +You may not remove the STREAMINFO block. +.TP +\f[B]--block-number=#[,#[\&...]]\f[R] +An optional comma-separated list of block numbers to display. +The first block, the STREAMINFO block, is block 0. +.PP +\f[B]--block-type=type[,type[\&...]]\f[R] +.TP +\f[B]--except-block-type=type[,type[\&...]]\f[R] +An optional comma-separated list of block types to be included or +ignored with this option. +Use only one of --block-type or --except-block-type. +The valid block types are: STREAMINFO, PADDING, APPLICATION, SEEKTABLE, +VORBIS_COMMENT, PICTURE. +You may narrow down the types of APPLICATION blocks selected by +appending APPLICATION with a colon and the ID of the APPLICATION block +in either ASCII or hexadecimal representation. +E.g. +APPLICATION:abcd for the APPLICATION block(s) whose textual +representation of the 4-byte ID is \[lq]abcd\[rq] or +APPLICATION:0xXXXXXXXX for the APPLICATION block(s) whose hexadecimal +big- endian representation of the 4-byte ID is \[lq]0xXXXXXXXX\[rq]. +For the example \[lq]abcd\[rq] above the hexadecimal equivalalent is +0x61626364 +.TP +\f[B]--application-data-format=hexdump|text\f[R] +If the application block you are displaying contains binary data but +your --data-format=text, you can display a hex dump of the application +data contents instead using --application-data-format=hexdump. +.TP +\f[B]--data-format=binary|binary-headerless|text\f[R] +For use with \[en]list. +By default a human-readable text representation of the data is isplayed. +You may specify \[en]data-format=binary to dump the raw binary form of +each metadata block. +Specify \[en]data-format=binary-headerless to omit output of metadata +block headers, including the id of APPLICATION metadata blocks. +.TP +\f[B]--append\f[R] +Insert a metadata block from a file. +This must be a binary block as exported with \[en]list +\[en]data-format=binary. +The insertion point is defined with \[en]block-number=#. +The new block will be added after the given block number. +This prevents the illegal insertion of a block before the first +STREAMINFO block. +You may not \[en]append another STREAMINFO block. +It is possible to copy a metadata block from one file to another with +this option. +For example use +\f[C]metaflac --list --data-format=binary --block-number=6 file.flac > block\f[R] +to export the block, and then import it with +\f[C]metaflac --append anotherfile.flac < block\f[R] +.TP +\f[B]--remove-all\f[R] +Remove all metadata blocks (except the STREAMINFO block) from the +metadata. +Unless --dont-use-padding is specified, the blocks will be replaced with +padding. +.TP +\f[B]--merge-padding\f[R] +Merge adjacent PADDING blocks into single blocks. +.TP +\f[B]--sort-padding\f[R] +Move all PADDING blocks to the end of the metadata and merge them into a +single block. +.SH SEE ALSO +.PP +\f[B]flac(1)\f[R] |
