Operating System (os)

Output the auto-detected OS name

Description

Output the auto-detected OS name.

Usage

os -> <stdout>

os string -> <stdout>

Examples

Name current platform

» os
linux

Check platforms

Or if you want to check if the host is one of a number of platforms:

# When run on Linux or FreeBSD
» os linux freebsd
true

# When run on another platform, eg Windows or Darwin (macOS)
# (exit number would also be `1`)
» os linux freebsd
false

The intention is this allows simple tests in scripts:

if { os windows } then {
    # run some Windows specific code
}

POSIX

posix is also supported to check if Murex is running on a UNIX-like operating system.

All Murex targets apart from Windows and Plan 9 are considered POSIX.

# When run on Linux or macOS
» os posix
true

# When run on Windows or Plan 9
# (exit number would also be `1`)
» os posix
false

Please note that although Plan 9 shares similarities with POSIX, it is not POSIX-compliant. For that reason, os returns false with the posix parameter when run on Plan 9. If you want to include Plan 9 in the check then please write it as os posix plan9.
