12       Set each NAME to VALUE in the environment and run COMMAND.
13

15       too.

OPTIONS

44   -S/--split-string usage in scripts
45       The  -S  option allows specifing multiple parameters in a script.  Run‐
46       ning a script named 1.pl containing the following first line:
47
48              #!/usr/bin/env -S perl -w -T
49
50       Will execute perl -w -T 1.pl .
51
52       Without the '-S' parameter the script will likely fail with:
53
54              /usr/bin/env: 'perl -w -T': No such file or directory
55
56       See the full documentation for more details.
