ENV(1) | User Commands | ENV(1) |
env - run a program in a modified environment
env [OPTION]... [-] [NAME=VALUE]... [COMMAND [ARG]...]
Set each NAME to VALUE in the environment and run COMMAND.
Mandatory arguments to long options are mandatory for short options too.
A mere - implies -i. If no COMMAND, print the resulting environment.
The -S option allows specifing multiple parameters in a script. Running a script named 1.pl containing the following first line:
#!/usr/bin/env -S perl -w -T
Will execute perl -w -T 1.pl .
Without the '-S' parameter the script will likely fail with:
/usr/bin/env: 'perl -w -T': No such file or directory
See the full documentation for more details.
