M1.x EPIC - How do I use the history substitution on the EPIC command line?

描述

Keywords: EPIC, history, substitution, command line

Urgency: Standard

General Description:
The EPIC command line functionality supports the use of history substitution using a syntax similar to CSH.

解决方案

Valid history operators are:
!? - Give help on EPIC history substitution.
! - Give a list of previous commands.
!! - Retrieve the previous command.
!* - Retrieve the 1st thru last words of the previous command.
!^ - Retrieve the first word of the previous command.
!$ - Retrieve the last word of the previous command.
!<num> - Retrieve previous <num> command.
!<txt> - Retrieve the last command whose first word matches <txt>
!?<txt> - Retrive the last command with any word matching <txt>
!:<num> - Retrieve the <num>th word of the previous command.
!:<n1>-<n2> - Retrieve the <n1>th through <n2>th words of the prev cmd.
!:s/<p1>/<p2>/g - Substitute <p2> for <p1> on prev cmd. The "g" is optional. Use it to sub all matches of <p1>.

The pattern separator char is whatever follows the '!:s'. Hence, !:s#a#b# is legal.

NOTE: The ':' colon operators may also be used in conjunction with the '!<num>' and '!<txt>' operators.

Examples: '!110:s/a/xxx/' or '!select:s/signal1/signal2/'.
