set Displays a list of predeﬁned and user deﬁned variables.

set var = exp Deﬁnes (or redeﬁnes) the speciﬁed dbx variable, setting its

value to that of the expression you provide.

sh Invokes a subshell. To return to dbx from the subshell, enter

exit at the command line, or otherwise terminate the

subshell.

sh com Executes the speciﬁed shell command. dbx interprets the

remainder of the line as a command to pass to the spawned

shell process, unless you enclose the command in double-

quotes or you terminate your shell command with a

semicolon (;).

showpgrp Shows the group process list and the group history.

showproc [pid | all]

Shows processes already in the dbx process pool or

processes that dbx can control. If you provide no arguments,

dbx lists the processes it already controls. If you provide a

pid, dbx displays the status of the speciﬁed process. If you

use argument “all,” dbx lists all the processes it controls as

well as all those processes it could control but that are not

yet added to the process pool.

source [ﬁle] Executes dbx commands from ﬁle.

status Displays all breakpoints, traces, and conditional

commands.

step [n] Executes the speciﬁed number of lines of source code,

stepping into procedures. If you do not provide an

argument, step executes one line. If step encounters any

breakpoints, it immediately stops execution.

stepi Single steps one machine instruction, stepping into

procedures (as called by jal and jalr). If stepi encounters any

breakpoints, it immediately stops execution.

stepi [n] Executes the speciﬁed number of machine instructions,

stepping into procedures (as called by jal and jalr).

stop at Set a breakpoint at the current source line.

stop at line Sets a breakpoint at the speciﬁed source line.
