Your program's arguments
========================

   The arguments to your program can be specified by the arguments of
the `run' command.  They are passed to a shell, which expands wildcard
characters and performs redirection of I/O, and thence to your program.
Your `SHELL' environment variable (if it exists) specifies what shell
GDB uses.  If you do not define `SHELL', GDB uses `/bin/sh'.

   `run' with no arguments uses the same arguments used by the previous
`run', or those set by the `set args' command.

`set args'
     Specify the arguments to be used the next time your program is
     run.  If `set args' has no arguments, `run' executes your program
     with no arguments.  Once you have run your program with arguments,
     using `set args' before the next `run' is the only way to run it
     again without arguments.

`show args'
     Show the arguments to give your program when it is started.
