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)
|
|
|
|
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
