usage_description="
|
|
Downloads and installs a binary from a given URL and extraction path to /usr/local/bin if run as root or ~/bin if run as user
|
|
|
|
The URL can be parameterized with {os} and {arch} tokens to be replaced by the current OS (linux/darwin) or Architecture (amd64/arm)
|
|
|
|
Environment overrides for {os} and {arch} if their values are Darwin, Linux, x86_64 or i386 respectively, in this order of priority:
|
|
|
|
export OS_DARWIN=macOS # because some packages use 'macOS' while others use 'darwin'
|
|
export OS_LINUX=Linux # because some packages titlecase this
|
|
|
|
export ARCH_X86_64=amd64 # because some packages use 'amd64' instead of 'x86_64'
|
|
export ARCH_X86=x86 # because some packages use 'x86' instead of 'i386'
|
|
export ARCH_OVERRIDE=all # because some packages use a random universal arch rather than 'x86_64' or 'i386'
|
|
|
|
If a zip or tarball is given, will be unpacked in /tmp and the binary path specified will be copied to bin
|
|
|
|
An optional binary destination can be given to name the file - if the file name is an absolute path will place it there instead of /usr/local/bin or ~/bin
