# syz-db
`syz-db` program can be used to manipulate corpus.db databases that are used
by syz-managers.
## Build
Build `syz-db` with `make db` or by changing to `tools/syz-db` and run `go build`.
## Options
`syz-db` currently overs the following generic arguments:
```shell
-arch string
target arch
-os string
target OS
-version uint
database version
-vv int
verbosity
```
That can be used with
```
syz-db pack dir corpus.db
```
to pack a database
```
syz-db unpack corpus.db dir
```
to unpack a database. A file containing performed syscalls will be returned.
```
syz-db merge dst-corpus.db add-corpus.db* add-prog*
```
to merge databases. No additional file will be created: The first file will be replaced by the merged result.
```
syz-db bench corpus.db
```
to run a deserialization benchmark. For example:
```
syz-db -os=linux -arch=amd64 bench corpus.db
```
could give an output like
```
allocs 123 MB (123 M), next GC 123 MB, sys heap 123 MB, live allocs 123 MB (123 M), time 324s.
```
