Another alternative, ksh syntax. This one requres *named* pipes! mkarcv file $(search "pattern" @(list lformat="%s%s" directory)) all Where the commands are run concurrently and the name or contents of a generated file is inserted where the @(...) or $(...) was. This would do effectively: run list >pipe:temp0001 lformat="%s%s" directory run search >pipe:temp0002 "pattern" pipe:temp0001 mkarcv file (contents of pipe:temp0002 inserted in the line here) So $(...) is (as in ksh) equivalent to the UNIX shell syntax `...`, and the @(...) means (insert pipe name here). The biggest advantage here is that existing Amiga commands will work well without being turned into filters. -- Peter da Silva. `-_-' <peter@sugar.hackercorp.com>.
