sed Debug

[Vaughn A. Hart]

Hi,

I am having a hard time learning sed... and I'd like to know what you mean :

SED PROGRAM:

  /1/ s/1/3/

INPUT:   'STDIN' line 1

PATTERN: 1

COMMAND: /1/ s/1/3/

MATCHED REGEX REGISTERS

  regex[0] = 0-1 '1'

PATTERN: 3

END-OF-CYCLE:

3


Print the input sed program in canonical form, and annotate program
execution.


Thanks!
