Usando sed para consolidar a saída do diff

Question

Eu tenho essa saída como resultado da comparação de arquivos com diff :

< IF-Name :STRING: "lns-wall-01-t2"       Index:Gge32: 260
---
> IF-Name :STRING: "lns-wall-01-t2"       Index:Gge32: 25

Eu preciso dessa saída:

lns-wall-01-t2 old:260 new:25

Eu quero usar sed.

    

Answer 1

com awk :

awk '
/^</ { old = $NF }
/^>/ { str = $4 ; gsub(/"/,"",str) ; printf "%s old:%s new:%s\n", str, old, $NF }
' your_files_list_here

    

Answer 2

sed '
    /^</{
        # first line formatting
        s/^.*"\(.*\)".*: / old:/
        # append next 2 lines
        N
        N
        # exchange from 2nd line begining till last ":" by "new"
        s/\n---.*: / new:/
        }' "$Rep_Scripts"/diff.txt

    

Answer 3

usa um tipo diferente de saída do diff:

diff -y --suppress-common-lines f1 f2

que oferece um formato mais fácil de usar:

F-Name :STRING: "lns-wall-01-t2"       Index:Gge32: 260   |IF-Name :STRING: "lns-wall-01-t2"       Index:Gge32: 25

e

diff -y ........ |
perl -nE '/"(.*?)".*?32:\s*(\d+).*32:\s*(\d+)/ 
          and say "$1 old:$2 new:$3"'
