cygwin sed substitution against commands in history
- by Ira
I couldn't find an answer for this exact problem, so I'll ask it.
I'm working in Cygwin and want to reference previous commands using !n notation, e.g., if command 5 was which ls, then !5 runs the same command.
The problem is when trying to do substitution, so running:
!5:s/which \([a-z]\)/\1/
should just run ls, or whatever the argument was for which for command number 5.
I've tried several ways of doing this kind of substitution and get the same error:
bash: :s/which \([a-z]*\)/\1/: substitution failed
