Re: [procmail] What Does This Variable Assignment Mean?

Toen ik Bill Polhemus kietelde, kwam er dit uit:

I was going through some PROCMAIL .cf files and came across this line:

SECURITY_NOTIFY=${SECURITY_NOTIFY:-"postmaster"}

See man sh:

${parameter:-word}
        Use Default Values.  If parameter is unset or null, the expansion
        of word is substituted; otherwise, the value of parameter is sub-
        stituted.
