There was a problem hiding this comment. On Linux, almost no command line tool is guaranteed to be installed. It's worth checking if all of the programs the script needs are installed.
mktemp and uname come from coreutils, but those are a bit too fundamental to bother checking for IMO. cd is a shell builtin. Or, you could detect apt-get and dnf and try to install the relevant packages to ensure they'll be there (without something like this: if command -v apt-get >/dev/null 2>&1 ; then # debian, ubuntu
apt-get update
apt-get install curl procps tar
elif command -v dnf >/dev/null 2>&1 ; then # rhel
dnf update
dnf install curl procps tar
elif command -v yum >/dev/null 2>&1 ; then # amazonlinux2
yum update
yum install curl procps tar
elif ! command -v curl >/dev/null 2>&1 || ! command -v ps >/dev/null 2>&1 || ! command -v tar >/dev/null 2>&1 ; then
echo "Missing one of more of the following programs: curl, ps, tar" >&2
exit 1
fiThere was a problem hiding this comment. Good call. I think that automatically running their package manager to install the missing utilities is a bit heavy-handed, so I just went with the fail-fast exit when one of the necessary commands is not present. |
