NAME
env - run a program in a modified environment
SYNOPSIS
env [OPTION]... [-] [NAME=VALUE]... [COMMAND [ARG]...]
DESCRIPTION
Set each NAME to VALUE in the environment and run COMMAND.
Mandatory
arguments to long options are mandatory for short options
too.
-i, --ignore-environment
start with an empty environment
-0, --null
end each output line with NUL, not newline
-u, --unset=NAME
remove variable from the environment
-C, --chdir=DIR
change working directory to DIR
-S, --split-string=S
process and split S into separate arguments; used to pass multiple arguments on shebang lines
-v, --debug
print verbose information for each processing step
--help |
display this help and exit |
--version
output version information and exit
A mere - implies -i. If no COMMAND, print the resulting environment.
OPTIONS
-S/--split-string
usage in scripts
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.
