You're not trying to use $an inside '' in this version. | `` still works inside ''. No. What is actually happening is that in _both_ cases the single quotes in his script are preventing $year _and_ the `command` stuff from happening. In his script! So what is being echoed for mutt to use is _literally_: set record==OUTBOX/$year/outbox-`date +%m-%y` or set record==OUTBOX/`date +%Y`/outbox-`date +%m-%y` Now, in both these cases, mutt _will_ try to expand both $year and the `date...` parts. However, mutt hasn't got a $year to use. The `date...` stuff _does_ work. The second script works because mutt does not try to use $year. | > How to use a variable with mutt ? | Hope this helps. You've been misled by red herrings, alas. Gérard, use Athanasius' suggestion of double quotes in your script. You're not passing $year to mutt, but you will be passing the result you want.
