I'm messing around with /sys/src/9/port/sysproc.c and I may have distorted it beyond recovery, but I have a feeling this problem isn't of my own making.
I have: ; cat /bin/ll #!/bin/ls -l ; If I invoke ll ; ll --rwxrwxr-x M 9 lucio lucio 13 Jan 31 09:30 /bin/ll ; no matter where I invoke it, not what I expect at all. I also have (my prompt is actually "term% ", in case it matters): ; cat /bin/en #!/bin/echo -n ; en /bin/en; Now, the question that makes this all very strange is: how does /rc/bin/service/tcp17010 which contains: #!/bin/cpu -R actually manage to work? I have broken it during the course of today, but using 9pccpu.gz off sources as I did now for confirmation, it seems to work. In summary, I think sysproc.c:/^sysexec is doing something wrong with the script header line. It is rather confusing code and I'm sure it was more robust last time I messed with it, probably over a year ago. I plan to fix it, but I need to understand what's broken first, and that bit I'm finding hard to do. Could someone with a stable version of Plan 9 please confirm that it isn't my mind that has suddenly slipped? ++L PS: invoking ; ll . may give an clearer view of the nature of the problem.
