This might be. If this is the case one could still strip the trailing percent-sign off the read string before the comparison. This is still faster than to fire off awk to parse a line. I haven't tried to come up with a full-blown solution but only a sketch exemplifying what i tried to explain.

Agreed your approach is good and I like the multiple use of the variable "junk" (I didn't know you could do that but I have now tested the idea).

We need real examples from the OP.

Of course you could call the variable any way you like. I habitually call it "junk" because this signifies its content. The technique is one of the leftovers from my REXX experience (i worked on mainframes before "downgrading" to midrange systems), where this is the normal way to do it. In REXX you even have a special variable "." for this, which is "throw-away", so to say.
