Despite invoking the nvi ":set nolock" command there are still locks on the file that is being edited which prevent certain actions. If the file is a script you get EBUSY when you try to run it. Reproducible: Always Steps to Reproduce: 1. echo -e "#! /bin/sh\necho hello" > runme 2. chmod 755 runme 3. nvi runme 4. :set nolock 5. ^Z 6. ./runme Actual Results: -bash: ./runme: /bin/sh: bad interpreter: Text file busy Expected Results: hello world Lock is set with this system call as observed via strace: flock(5, LOCK_EX|LOCK_NB)

Thanks for the report. nolock (as well as several other no* options) is incorrectly taken as an abbreviation for noprint, because the wide character support (USE=unicode) is broken wrt. options parsing. To get the lock option unset without rebuilding nvi, you can use "set nolockxxxxxxxxxxxx" as a hack; I'll fix this properly shortly in -r6. Note that after fixing this, trying to run a script being edited still results in "Text file busy"; this is not caused by the flock() system call.
Fixed in -r6.
