An archive is a single file holding 46 a collection of other files in a structure that makes it possible to 47 retrieve the original individual files (called archive members). 48 The original files' contents, mode (permissions), timestamp, owner, 49 and group are preserved in the archive, and can be restored on 50 extraction. 51 52 The stored filename is limited to 15 characters. (for more information 53 see long filename support). 54 ar has 60 bytes of overheads for every stored file. 55 56 This implementation of ar can extract archives, it cannot create or 57 modify them. 58 On an x86 system, the ar applet adds about 1K. 59 60 Unless you have a specific application which requires ar, you should 61 probably say N here. 62 63 config FEATURE_AR_LONG_FILENAMES 64 bool "Support for long filenames (not needed for debs)" 65 default y 66 depends on AR 67 help 68 By default the ar format can only store the first 15 characters 69 of the filename, this option removes that limitation. 70 It supports the GNU ar long filename method which moves multiple long 71 filenames into a the data section of a new ar entry. 72 73 config FEATURE_AR_CREATE 74 bool "Support archive creation" 75 default y 76 depends on AR 77 help 78 This enables archive creation (-c and -r) with busybox ar. 79 80 config BUNZIP2 81 bool "bunzip2" 82 default y 83 help 84 bunzip2 is a compression utility using the Burrows-Wheeler block 85 sorting text compression algorithm, and Huffman coding. Compression 86 is generally considerably better than that achieved by more 87 conventional LZ77/LZ78-based compressors, and approaches the 88 performance of the PPM family of statistical compressors. 89 90 Unless you have a specific application which requires bunzip2, you 91 should probably say N here. 92 93 config BZIP2 94 bool "bzip2" 95 default y 96 help 97 bzip2 is a compression utility using the Burrows-Wheeler block 98 sorting text compression algorithm, and Huffman coding. Compression 99 is generally considerably better than that achieved by more 100 conventional LZ77/LZ78-based compressors, and approaches the 101 performance of the PPM family of statistical compressors. 102 103 Unless you have a specific application which requires bzip2, you 104 should probably say N here. 105 106 config CPIO 107 bool "cpio" 108 default y 109 help 110 cpio is an archival utility program used to create, modify, and 111 extract contents from archives. 112 cpio has 110 bytes of overheads for every stored file. 113 114 This implementation of cpio can extract cpio archives created in the 115 "newc" or "crc" format, it cannot create or modify them. 116 117 Unless you have a specific application which requires cpio, you 118 should probably say N here. 119 120 config FEATURE_CPIO_O 121 bool "Support for archive creation" 122 default y 123 depends on CPIO 124 help 125 This implementation of cpio can create cpio archives in the "newc" 126 format only. 127 128 config FEATURE_CPIO_P 129 bool "Support for passthrough mode" 130 default y 131 depends on FEATURE_CPIO_O 132 help 133 Passthrough mode. Rarely used. 134 135 config DPKG 136 bool "dpkg" 137 default n 138 select FEATURE_SEAMLESS_GZ 139 help 140 dpkg is a medium-level tool to install, build, remove and manage 141 Debian packages. 142 143 This implementation of dpkg has a number of limitations, 144 you should use the official dpkg if possible. 145 146 config DPKG_DEB 147 bool "dpkg_deb" 148 default n 149 select FEATURE_SEAMLESS_GZ 150 help 151 dpkg-deb unpacks and provides information about Debian archives. 152 153 This implementation of dpkg-deb cannot pack archives. 154 155 Unless you have a specific application which requires dpkg-deb, 156 say N here. 157 158 config FEATURE_DPKG_DEB_EXTRACT_ONLY 159 bool "Extract only (-x)" 160 default n 161 depends on DPKG_DEB 162 help 163 This reduces dpkg-deb to the equivalent of 164 "ar -p <deb> data.tar.gz | tar -zx". However it saves space as none 165 of the extra dpkg-deb, ar or tar options are needed, they are linked 166 to internally. 167 168 config GUNZIP 169 bool "gunzip" 170 default y 171 help 172 gunzip is used to decompress archives created by gzip. 173 You can use the `-t' option to test the integrity of 174 an archive, without decompressing it. 175 176 config GZIP 177 bool "gzip" 178 default y 179 help 180 gzip is used to compress files. 181 It's probably the most widely used UNIX compression program. 182 183 config FEATURE_GZIP_LONG_OPTIONS 184 bool "Enable long options" 185 default y 186 depends on GZIP && LONG_OPTS 187 help 188 Enable use of long options, increases size by about 106 Bytes 189 190 config GZIP_FAST 191 int "Trade memory for gzip speed (0:small,slow - 2:fast,big)" 192 default 0 193 range 0 2 194 depends on GZIP 195 help 196 Enable big memory options for gzip. 197 0: small buffers, small hash-tables 198 1: larger buffers, larger hash-tables 199 2: larger buffers, largest hash-tables 200 Larger models may give slightly better compression 201 202 config LZOP 203 bool "lzop" 204 default y 205 help 206 Lzop compression/decompresion. 207 208 config LZOP_COMPR_HIGH 209 bool "lzop compression levels 7,8,9 (not very useful)" 210 default n 211 depends on LZOP 212 help 213 High levels (7,8,9) of lzop compression. These levels 214 are actually slower than gzip at equivalent compression ratios 215 and take up 3.2K of code. 216 217 config RPM2CPIO 218 bool "rpm2cpio" 219 default y 220 help 221 Converts a RPM file into a CPIO archive. 222 223 config RPM 224 bool "rpm" 225 default y 226 help 227 Mini RPM applet - queries and extracts RPM packages. 228 229 config TAR 230 bool "tar" 231 default y 232 help 233 tar is an archiving program. It's commonly used with gzip to 234 create compressed archives. It's probably the most widely used 235 UNIX archive program. 236 237 config FEATURE_TAR_CREATE 238 bool "Enable archive creation" 239 default y 240 depends on TAR 241 help 242 If you enable this option you'll be able to create 243 tar archives using the `-c' option. 244 245 config FEATURE_TAR_AUTODETECT 246 bool "Autodetect compressed tarballs" 247 default y 248 depends on TAR && (FEATURE_SEAMLESS_Z || FEATURE_SEAMLESS_GZ || FEATURE_SEAMLESS_BZ2 || FEATURE_SEAMLESS_LZMA || FEATURE_SEAMLESS_XZ) 249 help 250 With this option tar can automatically detect compressed 251 tarballs. Currently it works only on files (not pipes etc). 252 253 config FEATURE_TAR_FROM 254 bool "Enable -X (exclude from) and -T (include from) options)" 255 default y 256 depends on TAR 257 help 258 If you enable this option you'll be able to specify 259 a list of files to include or exclude from an archive. 260 261 config FEATURE_TAR_OLDGNU_COMPATIBILITY 262 bool "Support for old tar header format" 263 default y 264 depends on TAR || DPKG 265 help 266 This option is required to unpack archives created in 267 the old GNU format; help to kill this old format by 268 repacking your ancient archives with the new format. 269 270 config FEATURE_TAR_OLDSUN_COMPATIBILITY 271 bool "Enable untarring of tarballs with checksums produced by buggy Sun tar" 272 default y 273 depends on TAR || DPKG 274 help 275 This option is required to unpack archives created by some old 276 version of Sun's tar (it was calculating checksum using signed 277 arithmetic). It is said to be fixed in newer Sun tar, but "old" 278 tarballs still exist. 279 280 config FEATURE_TAR_GNU_EXTENSIONS 281 bool "Support for GNU tar extensions (long filenames)" 282 default y 283 depends on TAR || DPKG 284 help 285 With this option busybox supports GNU long filenames and 286 linknames. 287 288 config FEATURE_TAR_LONG_OPTIONS 289 bool "Enable long options" 290 default y 291 depends on TAR && LONG_OPTS 292 help 293 Enable use of long options, increases size by about 400 Bytes 294 295 config FEATURE_TAR_TO_COMMAND 296 bool "Support for writing to an external program" 297 default y 298 depends on TAR && FEATURE_TAR_LONG_OPTIONS 299 help 300 If you enable this option you'll be able to instruct tar to send 301 the contents of each extracted file to the standard input of an 302 external program. 303 304 config FEATURE_TAR_UNAME_GNAME 305 bool "Enable use of user and group names" 306 default y 307 depends on TAR 308 help 309 Enables use of user and group names in tar. This affects contents 310 listings (-t) and preserving permissions when unpacking (-p). 311 +200 bytes. 312 313 config FEATURE_TAR_NOPRESERVE_TIME 314 bool "Enable -m (do not preserve time) option" 315 default y 316 depends on TAR 317 help 318 With this option busybox supports GNU tar -m 319 (do not preserve time) option. 320 321 config FEATURE_TAR_SELINUX 322 bool "Support for extracting SELinux labels" 323 default n 324 depends on TAR && SELINUX 325 help 326 With this option busybox supports restoring SELinux labels 327 when extracting files from tar archives. 328 329 config UNCOMPRESS 330 bool "uncompress" 331 default n 332 help 333 uncompress is used to decompress archives created by compress. 334 Not much used anymore, replaced by gzip/gunzip. 335 336 config UNLZMA 337 bool "unlzma" 338 default y 339 help 340 unlzma is a compression utility using the Lempel-Ziv-Markov chain 341 compression algorithm, and range coding. Compression 342 is generally considerably better than that achieved by the bzip2 343 compressors. 344 345 The BusyBox unlzma applet is limited to decompression only. 346 On an x86 system, this applet adds about 4K. 347 348 config FEATURE_LZMA_FAST 349 bool "Optimize unlzma for speed" 350 default n 351 depends on UNLZMA 352 help 353 This option reduces decompression time by about 25% at the cost of 354 a 1K bigger binary. 355 356 config LZMA 357 bool "Provide lzma alias which supports only unpacking" 358 default y 359 depends on UNLZMA 360 help 361 Enable this option if you want commands like "lzma -d" to work. 362 IOW: you'll get lzma applet, but it will always require -d option. 363 364 config UNXZ 365 bool "unxz" 366 default y 367 help 368 unxz is a unlzma successor. 369 370 config XZ 371 bool "Provide xz alias which supports only unpacking" 372 default y 373 depends on UNXZ 374 help 375 Enable this option if you want commands like "xz -d" to work. 376 IOW: you'll get xz applet, but it will always require -d option. 377 378 config UNZIP 379 bool "unzip" 380 default y 381 help 382 unzip will list or extract files from a ZIP archive, 383 commonly found on DOS/WIN systems. The default behavior 384 (with no options) is to extract the archive into the 385 current directory. Use the `-d' option to extract to a 386 directory of your choice. 38 INSERT 387 39 388 40 endmenu
