Re^3: wrapper script to conditionally exec different perls? (#!->#!->#!->...)

[stackspace]

Tye proposed using a compiled language for the wrapper program. Indeed, a simple C program performs the desired wrapping perfectly. Thanks much!

I suspect my problem had to do with something being run via "sh -c", even when my wrapper was a perl script. I got the same "exec: format error" that Tye did when strace'ing my script.
