X\fB\&.\fP \fIfile\fP [ \fIarg\fP ... ]
XRead and execute commands from \fIfile\fP in the current shell
Xenvironment.
XIf \fIfile\fP does not contain a slash, the shell
Xlooks in the components of \fBpath\fP to find the directory
Xcontaining \fIfile\fP.
XIf any arguments \fIarg\fP are given,
Xthey become the positional parameters; the old positional
Xparameters are restored when the \fIfile\fP is done executing.
XThe exit status is the exit status of the last command executed.
X.TP

XWith no arguments, print the list of aliases in the form
X\fIname\fP=\fBvalue\fP on the standard output.
XFor each \fIname\fP with a corresponding \fIvalue\fP, define an alias
Xwith that value.
XA trailing space in \fIvalue\fP causes the next
Xword to be checked for alias substitution.
XIf the \-\fBg\fP flag is present, define a global alias; global aliases
Xare expanded even if they do not occur in command position.
XFor each \fIname\fP with no \fIvalue\fP, print the value of \fIname\fP,
Xif any.
XThe exit status is nonzero if a \fIname\fP (with no \fIvalue\fP)
Xgiven for which no alias has been defined.

XIf the \-\fBs\fP option is specified, bind each \fIin-string\fP
Xto each specified \fIout-string\fP. When \fIin-string\fP is typed,
X\fIout-string\fP will be pushed back and treated as input to the
Xline editor.

XThe arguments \fIfirst\fP and \fIlast\fP may be specified as a
Xnumber or as a string. A negative number is used as an offset
Xto the current history event number.
XA string specifies the most recent event
Xbeginning with the given string.
XAll substitutions \fIold\fP=\fInew\fP, if any, are then performed
Xon the commands.
XIf the \-\fBl\fP flag is given, the resulting commands are listed on
Xstandard output.
XOtherwise the editor program \fIename\fP is invoked on a file containing
Xthese history events. If \fIename\fP is not given, the value
