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 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.
