381.

Create a simple command invoked by NAME which runs COMMANDS.
Arguments on the command line along with NAME are passed to the
function as $0 .. $n.

382.

Run a set of commands in a group. This is one way to redirect an
entire set of commands.

383.

Equivalent to the JOB_SPEC argument to the `fg' command. Resume a
stopped or background job. JOB_SPEC can specify either a job name
or a job number. Following JOB_SPEC with a `&' places the job in
the background, as if the job specification had been supplied as an
argument to `bg'.

384.

The EXPRESSION is evaluated according to the rules for arithmetic
evaluation. Equivalent to "let EXPRESSION".

385.

Returns a status of 0 or 1 depending on the evaluation of the conditional
expression EXPRESSION. Expressions are composed of the same primaries used
by the `test' builtin, and may be combined using the following operators

[tab]( EXPRESSION )[tab]Returns the value of EXPRESSION
[tab]! EXPRESSION[tab]True if EXPRESSION is false; else false
[tab]EXPR1 && EXPR2[tab]True if both EXPR1 and EXPR2 are true; else false
[tab]EXPR1 || EXPR2[tab]True if either EXPR1 or EXPR2 is true; else false

When the `==' and `!=' operators are used, the string to the right of the
operator is used as a pattern and pattern matching is performed. The
&& and || operators do not evaluate EXPR2 if EXPR1 is sufficient to
determine the expression's value.

BASH_VERSION Version information for this Bash.
CDPATH A colon-separated list of directories to search
[tab][tab]for directries given as arguments to `cd'.
GLOBIGNORE[tab]A colon-separated list of patterns describing filenames to
[tab][tab]be ignored by pathname expansion.
HISTFILE The name of the file where your command history is stored.
HISTFILESIZE The maximum number of lines this file can contain.
HISTSIZE The maximum number of history lines that a running
[tab][tab]shell can access.
HOME The complete pathname to your login directory.
HOSTNAME[tab]The name of the current host.
HOSTTYPE The type of CPU this version of Bash is running under.
IGNOREEOF Controls the action of the shell on receipt of an EOF
[tab][tab]character as the sole input. If set, then the value
[tab][tab]of it is the number of EOF characters that can be seen
[tab][tab]in a row on an empty line before the shell will exit
[tab][tab](default 10). When unset, EOF signifies the end of input.
MACHTYPE[tab]A string describing the current system Bash is running on.
MAILCHECK[tab]How often, in seconds, Bash checks for new mail.
MAILPATH[tab]A colon-separated list of filenames which Bash checks
[tab][tab]for new mail.
OSTYPE[tab][tab]The version of Unix this version of Bash is running on.
PATH A colon-separated list of directories to search when
[tab][tab]looking for commands.
PROMPT_COMMAND A command to be executed before the printing of each
[tab][tab]primary prompt.
PS1 The primary prompt string.
PS2 The secondary prompt string.
PWD[tab][tab]The full pathname of the current directory.
SHELLOPTS[tab]A colon-separated list of enabled shell options.
TERM The name of the current terminal type.
TIMEFORMAT[tab]The output format for timing statistics displayed by the
[tab][tab]`time' reserved word.
auto_resume Non-null means a command word appearing on a line by
[tab][tab]itself is first looked for in the list of currently
[tab][tab]stopped jobs. If found there, that job is foregrounded.
[tab][tab]A value of `exact' means that the command word must
[tab][tab]exactly match a command in the list of stopped jobs. A
[tab][tab]value of `substring' means that the command word must
[tab][tab]match a substring of the job. Any other value means that
[tab][tab]the command must be a prefix of a stopped job.
histchars Characters controlling history expansion and quick
[tab][tab]substitution. The first character is the history
[tab][tab]substitution character, usually `!'. The second is
[tab][tab]the `quick substitution' character, usually `^'. The
[tab][tab]third is the `history comment' character, usually `#'.
HISTIGNORE[tab]A colon-separated list of patterns used to decide which
[tab][tab]commands should be saved on the history list.

387.

Adds a directory to the top of the directory stack, or rotates
the stack, making the new top of the stack the current working
directory. With no arguments, exchanges the top two directories.

+N[tab]Rotates the stack so that the Nth directory (counting
[tab]from the left of the list shown by `dirs', starting with
[tab]zero) is at the top.

-N[tab]Rotates the stack so that the Nth directory (counting
[tab]from the right of the list shown by `dirs', starting with
[tab]zero) is at the top.

-n[tab]suppress the normal change of directory when adding directories
[tab]to the stack, so only the stack is manipulated.

dir[tab]adds DIR to the directory stack at the top, making it the
[tab]new current working directory.

You can see the directory stack with the `dirs' command.

388.

Removes entries from the directory stack. With no arguments,
removes the top directory from the stack, and cd's to the new
top directory.

+N[tab]removes the Nth entry counting from the left of the list
[tab]shown by `dirs', starting with zero. For example: `popd +0'
[tab]removes the first directory, `popd +1' the second.

-N[tab]removes the Nth entry counting from the right of the list
[tab]shown by `dirs', starting with zero. For example: `popd -0'
[tab]removes the last directory, `popd -1' the next to last.

-n[tab]suppress the normal change of directory when removing directories
[tab]from the stack, so only the stack is manipulated.

You can see the directory stack with the `dirs' command.

389.

Display the list of currently remembered directories. Directories
find their way onto the list with the `pushd' command; you can get
back up through the list with the `popd' command.

The -l flag specifies that `dirs' should not print shorthand versions
of directories which are relative to your home directory. This means
that `~/bin' might be displayed as `/homes/bfox/bin'. The -v flag
causes `dirs' to print the directory stack with one entry per line,
prepending the directory name with its position in the stack. The -p
flag does the same thing, but the stack position is not prepended.
The -c flag clears the directory stack by deleting all of the elements.

+N[tab]displays the Nth entry counting from the left of the list shown by
[tab]dirs when invoked without options, starting with zero.

-N[tab]displays the Nth entry counting from the right of the list shown by
[tab]dirs when invoked without options, starting with zero.

390.

Toggle the values of variables controlling optional behavior.
The -s flag means to enable (set) each OPTNAME; the -u flag
unsets each OPTNAME. The -q flag suppresses output; the exit
status indicates whether each OPTNAME is set or unset. The -o
option restricts the OPTNAMEs to those defined for use with
`set -o'. With no options, or with the -p option, a list of all
settable options is displayed, with an indication of whether or
not each is set.
