[bug #22100] Enhancement request: "grep foo | grep bar" in one process (i.e. line-selector and pattern selector)

[Paolo Bonzini]

Update of bug #22100 (project grep):

                  Status:                    None => Wont Fix               
             Open/Closed:                    Open => Closed

Follow-up Comment #2:

I think you really should use sed:

grep -l "Sherlock Holmes" * | xargs sed -rn 
   's/^Email: (address@hidden)$/1/p'

In fact, the proposed --file-match cannot be implemented with a single scan
of the file (and that's all you can do if the input is a pipe).

If anything, it may be interesting to implement --and / --or like git grep.
