uses the JOB abstraction as the basis for job control.
To facilitate the implementation of the user interface to job
control, the operating system maintains the notion of a current terminal
process group ID. Members of this process group (processes whose
process group ID is equal to the current terminal process group ID)
receive keyboard-generated signals such as ‘SIGINT’. These processes
are said to be in the foreground. Background processes are those whose
process group ID differs from the terminal's; such processes are immune
to keyboard-generated signals. Only foreground processes are allowed to
read from or, if the user so specifies with ‘stty tostop’, write to the
terminal. Background processes which attempt to read from (write to

caught, suspends the process.

maintains the notion of a current terminal process group ID. Processes
that have the same process group ID are said to be part of the same
“process group”. Members of the foreground process group (processes
whose process group ID is equal to the current terminal process group
ID) receive keyboard-generated signals such as ‘SIGINT’. Processes in
the foreground process group are said to be foreground processes.

Only foreground processes are allowed to read from or, if the user so

effect) the terminal are sent a ‘SIGTTIN’ (‘SIGTTOU’) signal by the
kernel's terminal driver, which, unless caught, suspends the process.
If the operating system on which Bash is running supports job
control, Bash contains facilities to use it. Typing the “suspend”
character (typically ‘^Z’, Control-Z) while a process is running causes
that process to be stopped and returns control to Bash. Typing the
“delayed suspend” character (typically ‘^Y’, Control-Y) causes the
process to be stopped when it attempts to read input from the terminal,
and control to be returned to Bash. The user then manipulates the state
of this job, using the ‘bg’ command to continue it in the background,
the ‘fg’ command to continue it in the foreground, or the ‘kill’ command
to kill it. A ‘^Z’ takes effect immediately, and has the additional
side effect of causing pending output and typeahead to be discarded.

There are a number of ways to refer to a job in the shell. The
character ‘%’ introduces a job specification (“jobspec”).
There are a number of ways to refer to a job in the shell. The ‘%’
character introduces a “job specification” (jobspec).
Job number ‘n’ may be referred to as ‘%n’. The symbols ‘%%’ and ‘%+’
refer to the shell's notion of the current job, which is the last job
stopped while it was in the foreground or started in the background. A
single ‘%’ (with no accompanying job specification) also refers to the
current job. The previous job may be referenced using ‘%-’. If there
is only a single job, ‘%+’ and ‘%-’ can both be used to refer to that
job. In output pertaining to jobs (e.g., the output of the ‘jobs’
command), the current job is always flagged with a ‘+’, and the previous
job with a ‘-’.
Job number ‘n’ may be referred to as ‘%n’. A job may also be
referred to using a prefix of the name used to start it, or using a
substring that appears in its command line. For example, ‘%ce’ refers
to a job whose command name begins with ‘ce’. Using ‘%?ce’, on the
other hand, refers to any job containing the string ‘ce’ in its command
line. If the prefix or substring matches more than one job, Bash
reports an error.
A job may also be referred to using a prefix of the name used to
start it, or using a substring that appears in its command line. For
example, ‘%ce’ refers to a stopped job whose command name begins with
‘ce’. Using ‘%?ce’, on the other hand, refers to any job containing the
string ‘ce’ in its command line. If the prefix or substring matches
more than one job, Bash reports an error.
The symbols ‘%%’ and ‘%+’ refer to the shell's notion of the “current
job”. A single ‘%’ (with no accompanying job specification) also refers
to the current job. ‘%-’ refers to the “previous job”. When a job
starts in the background, a job stops while in the foreground, or a job
is resumed in the background, it becomes the current job. The job that
was the current job becomes the previous job. When the current job
terminates, the previous job becomes the current job. If there is only
a single job, ‘%+’ and ‘%-’ can both be used to refer to that job. In
output pertaining to jobs (e.g., the output of the ‘jobs’ command), the
current job is always marked with a ‘+’, and the previous job with a
‘-’.
Simply naming a job can be used to bring it into the foreground: ‘%1’
is a synonym for ‘fg %1’, bringing job 1 from the background into the
foreground. Similarly, ‘%1 &’ resumes job 1 in the background,
equivalent to ‘bg %1’
equivalent to ‘bg %1’.
The shell learns immediately whenever a job changes state. Normally,
Bash waits until it is about to print a prompt before reporting changes
in a job's status so as to not interrupt any other output, though it
will notify of changes in a job's status after a foreground command in a
list completes, before executing the next command. If the ‘-b’ option
to the ‘set’ builtin is enabled, Bash reports such changes immediately
(*note The Set Builtin::). Any trap on ‘SIGCHLD’ is executed for each
child process that exits.

about changes in a job's status so as to not interrupt any other output,
though it will notify of changes in a job's status after a foreground
command in a list completes, before executing the next command in the
list. If the ‘-b’ option to the ‘set’ builtin is enabled, Bash reports
such changes immediately (*note The Set Builtin::). Bash executes any
trap on ‘SIGCHLD’ for each child process that terminates.
If an attempt to exit Bash is made while jobs are stopped, (or
running, if the ‘checkjobs’ option is enabled - see *note The Shopt
Builtin::), the shell prints a warning message, and if the ‘checkjobs’
option is enabled, lists the jobs and their statuses. The ‘jobs’
command may then be used to inspect their status. If a second attempt
to exit is made without an intervening command, Bash does not print
another warning, and any stopped jobs are terminated.
When a job terminates and Bash notifies the user about it, Bash
removes the job from the jobs table. It will not appear in ‘jobs’
output, but ‘wait’ will report its exit status, as long as it's supplied
the process ID associated with the job as an argument. When the table
is empty, job numbers start over at 1.
