| Welcome to sstate cache management utilities. |
| sstate-cache-management.sh <OPTION> |
| |
| Options: |
| -h, --help |
| Display this help and exit. |
| |
| --cache-dir=<sstate cache dir> |
| Specify sstate cache directory, will use the environment |
| variable SSTATE_CACHE_DIR if it is not specified. |
| |
| --extra-archs=<arch1>,<arch2>...<archn> |
| Specify list of architectures which should be tested, this list |
| will be extended with native arch, allarch and empty arch. The |
| script won't be trying to generate list of available archs from |
| AVAILTUNES in tune files. |
| |
| --extra-layer=<layer1>,<layer2>...<layern> |
| Specify the layer which will be used for searching the archs, |
| it will search the meta and meta-* layers in the top dir by |
| default, and will search meta, meta-*, <layer1>, <layer2>, |
| ...<layern> when specified. Use "," as the separator. |
| |
| This is useless for --stamps-dir or when --extra-archs is used. |
| |
| -d, --remove-duplicated |
| Remove the duplicated sstate cache files of one package, only |
| the newest one will be kept. The duplicated sstate cache files |
| of one package must have the same arch, which means sstate cache |
| files with multiple archs are not considered duplicate. |
| |
| Conflicts with --stamps-dir. |
| |
| --stamps-dir=<dir1>,<dir2>...<dirn> |
| Specify the build directory's stamps directories, the sstate |
| cache file which IS USED by these build diretories will be KEPT, |
| other sstate cache files in cache-dir will be removed. Use "," |
| as the separator. For example: |
| --stamps-dir=build1/tmp/stamps,build2/tmp/stamps |
| |
| Conflicts with --remove-duplicated. |
| |
| -L, --follow-symlink |
| Remove both the symbol link and the destination file, default: no. |
| |
| -y, --yes |
| Automatic yes to prompts; assume "yes" as answer to all prompts |
| and run non-interactively. |
| |
| -v, --verbose |
| Explain what is being done. |
| |
| -D, --debug |
| Show debug info, repeat for more debug info. |
