Subject: PR gdb/21574: Mention $SHELL and startup-with-shell on "help run"
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=45159d6ad394fe7db840b2b92eaa69508b8a8fe7;p=deliverable%2Fbinutils-gdb.git

PR gdb/21574: Mention $SHELL and startup-with-shell on "help run"

This simple patch updates the documentation of "help run" in order to
mention that the shell used to start the inferior comes from the
$SHELL environment variable.  It also mentions that this behaviour can
be disabled by using the "set startup-with-shell off" command.
