Suspend the execution of this shell until it receives a SIGCONT
signal. The `-f' if specified says not to complain about this
being a login shell if it is; just suspend anyway.

366.

Exits with a status of 0 (true) or 1 (false) depending on
the evaluation of EXPR. Expressions may be unary or binary. Unary
expressions are often used to examine the status of a file. There
are string operators as well, and numeric comparison operators.

File operators:

-a FILE True if file exists.
-b FILE True if file is block special.
-c FILE True if file is character special.
-d FILE True if file is a directory.
-e FILE True if file exists.
-f FILE True if file exists and is a regular file.
-g FILE True if file is set-group-id.
-h FILE True if file is a symbolic link.
-L FILE True if file is a symbolic link.
-k FILE True if file has its `sticky' bit set.
-p FILE True if file is a named pipe.
-r FILE True if file is readable by you.
-s FILE True if file exists and is not empty.
-S FILE True if file is a socket.
-t FD True if FD is opened on a terminal.
-u FILE True if the file is set-user-id.
-w FILE True if the file is writable by you.
-x FILE True if the file is executable by you.
-O FILE True if the file is effectively owned by you.
-G FILE True if the file is effectively owned by your group.
-N FILE True if the file has been modified since it was last read.

FILE1 -nt FILE2 True if file1 is newer than file2 (according to
modification date).

FILE1 -ot FILE2 True if file1 is older than file2.

FILE1 -ef FILE2 True if file1 is a hard link to file2.

String operators:

-z STRING True if string is empty.

-n STRING
STRING True if string is not empty.

STRING1 = STRING2
True if the strings are equal.
STRING1 != STRING2
True if the strings are not equal.
STRING1 < STRING2
True if STRING1 sorts before STRING2 lexicographically.
STRING1 > STRING2
True if STRING1 sorts after STRING2 lexicographically.

Other operators:

-o OPTION True if the shell option OPTION is enabled.
! EXPR True if expr is false.
EXPR1 -a EXPR2 True if both expr1 AND expr2 are true.
EXPR1 -o EXPR2 True if either expr1 OR expr2 is true.

arg1 OP arg2 Arithmetic tests. OP is one of -eq, -ne,
-lt, -le, -gt, or -ge.

Arithmetic binary operators return true if ARG1 is equal, not-equal,
less-than, less-than-or-equal, greater-than, or greater-than-or-equal
than ARG2.

This is a synonym for the "test" builtin, but the last
argument must be a literal `]', to match the opening `['.

369.

The command ARG is to be read and executed when the shell receives
signal(s) SIGNAL_SPEC. If ARG is absent (and a single SIGNAL_SPEC
is supplied) or `-', each specified signal is reset to its original
value. If ARG is the null string each SIGNAL_SPEC is ignored by the
shell and by the commands it invokes. If a SIGNAL_SPEC is EXIT (0)
the command ARG is executed on exit from the shell. If a SIGNAL_SPEC
is DEBUG, ARG is executed after every simple command. If the`-p' option
is supplied then the trap commands associated with each SIGNAL_SPEC are
displayed. If no arguments are supplied or if only `-p' is given, trap
prints the list of commands associated with each signal. Each SIGNAL_SPEC
is either a signal name in <signal.h> or a signal number. Signal names
are case insensitive and the SIG prefix is optional. `trap -l' prints
a list of signal names and their corresponding numbers. Note that a
signal can be sent to the shell with "kill -signal $$".

370.

For each NAME, indicate how it would be interpreted if used as a
command name.

If the -t option is used, `type' outputs a single word which is one of
`alias', `keyword', `function', `builtin', `file' or `', if NAME is an
alias, shell reserved word, shell function, shell builtin, disk file,
or unfound, respectively.

If the -p flag is used, `type' either returns the name of the disk
file that would be executed, or nothing if `type -t NAME' would not
return `file'.

If the -a flag is used, `type' displays all of the places that contain
an executable named `file'. This includes aliases, builtins, and
functions, if and only if the -p flag is not also used.

The -f flag suppresses shell function lookup.

The -P flag forces a PATH search for each NAME, even if it is an alias,
builtin, or function, and returns the name of the disk file that would
be executed.

Ulimit provides control over the resources available to processes
started by the shell, on systems that allow such control. If an
option is given, it is interpreted as follows:

-S[tab]use the `soft' resource limit
-H[tab]use the `hard' resource limit
-a[tab]all current limits are reported
-c[tab]the maximum size of core files created
-d[tab]the maximum size of a process's data segment
-e[tab]the maximum scheduling priority (`nice')
-f[tab]the maximum size of files written by the shell and its children
-i[tab]the maximum number of pending signals
-l[tab]the maximum size a process may lock into memory
-m[tab]the maximum resident set size
-n[tab]the maximum number of open file descriptors
-p[tab]the pipe buffer size
-q[tab]the maximum number of bytes in POSIX message queues
-r[tab]the maximum real-time scheduling priority
-s[tab]the maximum stack size
-t[tab]the maximum amount of cpu time in seconds
-u[tab]the maximum number of user processes
-v[tab]the size of virtual memory
-x[tab]the maximum number of file locks

If LIMIT is given, it is the new value of the specified resource;
the special LIMIT values `soft', `hard', and `unlimited' stand for
the current soft limit, the current hard limit, and no limit, respectively.
Otherwise, the current value of the specified resource is printed.
If no option is given, then -f is assumed. Values are in 1024-byte
increments, except for -t, which is in seconds, -p, which is in
increments of 512 bytes, and -u, which is an unscaled number of
processes.

372.

The user file-creation mask is set to MODE. If MODE is omitted, or if
`-S' is supplied, the current value of the mask is printed. The `-S'
option makes the output symbolic; otherwise an octal number is output.
If `-p' is supplied, and MODE is omitted, the output is in a form
that may be used as input. If MODE begins with a digit, it is
interpreted as an octal number, otherwise it is a symbolic mode string
like that accepted by chmod(1).

373.

Wait for the specified process and report its termination status. If
N is not given, all currently active child processes are waited for,
and the return code is zero. N may be a process ID or a job
specification; if a job spec is given, all processes in the job's
pipeline are waited for.

374.

Wait for the specified process and report its termination status. If
N is not given, all currently active child processes are waited for,
and the return code is zero. N is a process ID; if it is not given,
all child processes of the shell are waited for.

375.

The `for' loop executes a sequence of commands for each member in a
list of items. If `in WORDS ...;' is not present, then `in "$@"' is
assumed. For each element in WORDS, NAME is set to that element, and
the COMMANDS are executed.
