## dlv redirect

Help about file redirection.

### Synopsis


The standard file descriptors of the target process can be controlled using the '-r' and '--tty' arguments. 

The --tty argument allows redirecting all standard descriptors to a terminal, specified as an argument to --tty.

The syntax for '-r' argument is:

		-r [source:]destination

Where source is one of 'stdin', 'stdout' or 'stderr' and destination is the path to a file. If the source is omitted stdin is used implicitly.

File redirects can also be changed using the 'restart' command.


### Options inherited from parent commands

```
      --accept-multiclient               Allows a headless server to accept multiple client connections.
      --allow-non-terminal-interactive   Allows interactive sessions of Delve that don't have a terminal as stdin, stdout and stderr
      --api-version int                  Selects API version when headless. New clients should use v2. Can be reset via RPCServer.SetApiVersion. See Documentation/api/json-rpc/README.md. (default 1)
      --backend string                   Backend selection (see 'dlv help backend'). (default "default")
      --build-flags string               Build flags, to be passed to the compiler.
      --check-go-version                 Checks that the version of Go in use is compatible with Delve. (default true)
      --disable-aslr                     Disables address space randomization
      --headless                         Run debug server only, in headless mode.
      --init string                      Init file, executed by the terminal client.
  -l, --listen string                    Debugging server listen address. (default "127.0.0.1:0")
      --log                              Enable debugging server logging.
      --log-dest string                  Writes logs to the specified file or file descriptor (see 'dlv help log').
      --log-output string                Comma separated list of components that should produce debug output (see 'dlv help log')
      --only-same-user                   Only connections from the same user that started this instance of Delve are allowed to connect. (default true)
  -r, --redirect stringArray             Specifies redirect rules for target process (see 'dlv help redirect')
      --wd string                        Working directory for running the program.
```

cmd,proc,terminal,debugger: Support default file descriptor redirects Adds features to support default file descriptor redirects for the target process: 1. A new command line flag '--redirect' and '-r' are added to specify file redirects for the target process 2. New syntax is added to the 'restart' command to specify file redirects. 3. Interactive instances will check if stdin/stdout and stderr are terminals and print a helpful error message if they aren't. 2020-08-21 14:14:02 +00:00			`## dlv redirect`
