1 7.3 Job Control Variables
1 =========================
1
1 'auto_resume'
1 This variable controls how the shell interacts with the user and
1 job control. If this variable exists then single word simple
1 commands without redirections are treated as candidates for
1 resumption of an existing job. There is no ambiguity allowed; if
1 there is more than one job beginning with the string typed, then
1 the most recently accessed job will be selected. The name of a
1 stopped job, in this context, is the command line used to start it.
1 If this variable is set to the value 'exact', the string supplied
1 must match the name of a stopped job exactly; if set to
1 'substring', the string supplied needs to match a substring of the
1 name of a stopped job. The 'substring' value provides
11 functionality analogous to the '%?' job ID (⇒Job Control
Basics). If set to any other value, the supplied string must be
1 a prefix of a stopped job's name; this provides functionality
1 analogous to the '%' job ID.
