-.TH HISTORY 1 "30 July 1991"
-.SH NAME
-\-, \-\|\-, \-p, \-\|\-p \- shell history programs
-.SH SYNOPSIS
-.B \-
-.RI [ pattern ...]
-.RI [ substitution ...]
-.SH DESCRIPTION
-This set of programs provides a crude history mechanism for the shell
-.IR rc (1).
-It is based on the v8 UNIX programs
-.IR = ,
-.IR == ,
-etc.
-.PP
-The program
-.RI `` \- ''
-runs the shell on the command it is requested to find.
-The program
-.RI `` \-\|\- ''
-edits that command first.
-The programs
-.RI `` \-p ''
-and
-.RI `` \-\|\-p ''
-are similar, except that they print the final command on their standard
-output instead of running the shell.
-.PP
-The commands work by looking for a file
-named by the environment variable
-.Cr $history ,
-and by searching for previous commands in this file.
-Old commands can be edited,
-or simply re-executed according to the rules below:
-.PP
-A command is searched for by examining the lines in
-.Cr $history
-in reverse order.
-Lines which contain a previous invocation of the history
-program itself are ignored.
-If one or more
-.I pattern
-is supplied on the command line,
-then the patterns are used as a means of
-limiting the search.
-Patterns match any substring of a previous command,
-and if more than one pattern is present then all patterns must be
-matched before a command is selected.
-.PP
-Substitutions may also be specified on the command line.
-These have the syntax:
-.Ds
-.Ic old :[:...] new
-.De
-.PP
-(Note that the
-.I old
-pattern is used as a search-limiting pattern also.)
-Substitutions happen from left to right and are repeated according to the
-number of colons specified.
-.PP
-Finally, if the program was invoked as
-.RI `` -- ''
-or
-.RI `` --p '',
-a command may be edited in a crude line-mode fashion. The line to be
-edited is printed out, and below it the user supplies modifications to
-the command.
-.TP
-.B any character except those below
-Replaces the character above.
-.TP
-.B space or tab
-Skips over the above character(s).
-.TP
-.B #
-Deletes one character.
-.TP
-.B %
-Replaces one character with a space.
-.TP
-.B ^
-Inserts the rest of the typed line just before the character.
-.TP
-.B $
-Deletes the rest of the line from that character on, and replaces
-it with the rest of the typed line.
-.TP
-.B +
-Appends the rest of the typed line.
-.TP
-.B \-
-Backs up to a previous command satisfying the same matching
-constraints.
-.TP
-.B end of line
-If any changes have been made, the command is printed out again for
-further editing. If no changes have been made, the command is executed
-or printed, and the program exits.
-.TP
-.B end of file
-If an end-of-file is read from the keyboard by the editor,
-it aborts with exit status 1 and does not produce any output.
-.SH EXAMPLES
-The history programs work best when their output is reinterpreted by
-the shell using an
-.Cr eval
-command.
-This can be achieved by writing a shell function to perform the
-reinterpretation:
-.Ds
-.Cr "fn - -- {"
-.Cr " comm = \`{$0^p $*}"
-.Cr " if (! ~ $#comm 0) {"
-.Cr " echo $comm >[1=2]"
-.Cr " eval $comm"
-.Cr " }"
-.Cr "}"
-.De
-.PP
-Stuttering the `:' in a substitution allows things like:
-.Ds
-; prog 1 2 3 abc > /very/long/path/abc.out
-etc.
-- prog abc::xyz
-prog 1 2 3 xyz > /very/long/path/xyz.out
-;
-.De
