A tool for #! scripts with more than one argument.
On most modern systems, the kernel will only pass one argument to
a shebang interpreter script. Some tools, like perl and ruby, work
around this by parsing the shebang line themselves. long-shebang is a
more general solution: it will parse the second line as a shebang
line, with arbitrary numbers of arguments. As an additional convenience,
the program to be run can be looked up in PATH.
#!/usr/bin/env long-shebang
#!sh -e
false
true
will fail with exit code 1
The following escapes are recognized in the second #! line:
\\: A literal\\n: A newline\(backslash-space): A space rather than an argument delimiter\a: If this is the first argument on the second#!line, don't treat the program name asargv[0]. For example, a script with#!\a sh bash -ewill be equivalent toexecvp("sh", {"bash", "-e", script, NULL})rather thanexecvp("sh", {"sh", "bash", "-e", script, NULL}).
