Shebang #! invocation doesn't work as intended on *BSD targets

[filippsen]

Bug report

#!/usr/local/bin/space [args] does not work on *BSD boxes

Steps to reproduce 1

a.sh

$ cat a.sh
#!./b.sh These args should be all arg1

b.sh

$ cat b.sh
#!/bin/env bash
echo "1 (all shebang args): $1"
echo "2 (should be filename): $2"
echo "Here should come user args"
echo 3: $3
echo 4: $4
echo 5: $5
echo 6: $6
echo 7: $7
echo 8: $8

Output

$ ./a.sh A B C
<nothing>

Changing a.sh shebang line

$ cat a.sh 
#!/usr/bin/env ./b.sh arg1 arg2 arg3 arg4
$ ./a.sh A B C
1 (all shebang args): arg1
2 (should be filename): arg2
Here should come user args
3: arg3
4: arg4
5: ./a.sh
6: A
7: B
8: C

Steps to reproduce 2

Setup 1-a

Config

cat a.sh 
#!./b.sh These args should be all arg1

cat b.sh
cat b.sh 
#!/usr/bin/env bash
echo "1 (all shebang args): $1"
echo "2 (should be filename): $2"
echo "Here should come user args"
echo 3: $3
echo 4: $4
echo 5: $5
echo 6: $6
echo 7: $7
echo 8: $8

Run

./a.sh A B C D
<nothing>
echo $?
0

Setup 1-b (a.sh shebang variation)

Config

cat a.sh 
#!/usr/bin/env ./b.sh arg1 arg2 arg3 arg4

Run

./a.sh A B C D 
env: ./b.sh arg1 arg2 arg3 arg4: No such file or directory

Setup 1-c (b.sh shebang variation)

Config

cat b.sh 
#!/usr/local/bin/bash
echo "1 (all shebang args): $1"
echo "2 (should be filename): $2"
echo "Here should come user args"
echo 3: $3
echo 4: $4
echo 5: $5
echo 6: $6
echo 7: $7
echo 8: $8

Run

./b.sh 123 213 444 
1 (all shebang args): 123
2 (should be filename): 213
Here should come user args
3: 444
4:

7:
8:

Setup 2 - shebang_bsd

Run

./test/exit_status_cases/shebang_bsd.sh
env: space ! -m utils /waitforfile/ -- 1 !: No such file or directory

Expected output

$ ./a.sh A B C
1 (all shebang args): These args should be all arg1
2 (should be filename): ./a.sh
Here should come user args
3: A
4: B
5: C
