How do I write this precisely ?
You grab them into MATCH and then pass that on to the variables you
want to save them in. (The whitespace in the square brackets consists
of one space and one tab; this is to strip any leading whitespace from
the values we grab.)
:0
* ^From:[ ]*\/[^ ].*
{ FROM="$MATCH" }
:0
* ^To:[ ]*\/[^ ].*
{ TO="$MATCH" }
:0
* ^Cc:[ ]*\/[^ ].*
{ CC="$MATCH" }
If any of those fields is not present, the corresponding variable will
remain unchanged (unset, unless you already set it to something else).
I want to have these values in environment
variables, for I want to call an external program with
them as parameters (and also with the value of FOUND,
mentionned in previous posts).
If it's a program you write yourself, you might seriously consider
adding primitive mail header parsing to the program itself.
This obviously doesn't attempt to parse the fields in any way (such as
remove any comments from the To: field, i.e. reduce "era eriksson
<era(_at_)iki(_dot_)fi>" to just "era(_at_)iki(_dot_)fi") but I hope that's not
what you
were asking for, either.
