# install.sh — download the emcli binary from the project's release assets and
|
|
# put it on your PATH. Detects OS/arch, verifies the checksum when available.
|
|
#
|
|
# Usage:
|
|
# bash install.sh
|
|
#
|
|
# Environment overrides:
|
|
# EMCLI_VERSION release tag to fetch (default: v0.5.0)
|
|
# EMCLI_BASE_URL repo base URL (default: https://gitea.dcglab.co.uk/steve/emcli)
|
|
# EMCLI_INSTALL_DIR where to put the binary (default: $HOME/.local/bin)
|
|
#
|
|
# Release assets follow this naming scheme:
|
|
# emcli_<version>_<os>_<arch>[.exe] e.g. emcli_0.5.0_linux_amd64
|
|
# checksums.txt (sha256, one "<sum> <asset>" line per asset)
