Ability to read hostname from env

[fredrik-rambris]

Often you are working with a single Amiga. It would be nice if say SQUIRT_HOST is set in env then the hostname command line argument could be skipped

You can already get this just by using shell functions as wrapper, I use the variable AMIHOST with a default vaule 10.99.0.2

amiget () {
  squirt_suck ${AMIHOST:-10.99.0.2} ${1} >&2
}
amiput () {
  if test -n "${2}"
    then
      squirt --dest="${2}" ${AMIHOST:-10.99.0.2} ${1} >&2
    else
      squirt ${AMIHOST:-10.99.0.2} ${1} >&2
  fi
}
