# cqrun - a wrapper around Cobalt's qsub and cqwait
#
# Example:
#   $ cqrun [--dotfile=foo] -n 1 -q debug -t 20:00 -- some shell command
# Note that the "--" is required.
#
# BUGS:
#   One can use double-quotes, but not single-quotes, in the shell command
#
## Remote path:
if [ "x$1" = "x--cqrun-at-remote" ]; then
  shift
  if expr "x$1" : "x--dotfile=" >/dev/null 2>&1; then
    for filename in $(tr ',' ' ' <<<${1##*=}); do source $filename; done
    shift
  fi
  exec env "$@"
fi
#
## Normal path:
cmd='qsub '
helper="$(cd $(dirname $0) && pwd)/$(basename $0) --cqrun-at-remote"
while [ $# -ne 0 ]; do
  word="$1"; shift
  if expr "x$word" : "x--dotfile=" >/dev/null 2>&1; then
    helper="$helper $word"
  else
    [ x$word = x-- ] && break
    cmd="$cmd $word"
  fi
done
cmd="$cmd -e \\\$jobid.output --mode script $helper \"'$1'"; shift
while [ $# -ne 0 ]; do
  word="$1"; shift
  cmd="$cmd '$word'"
done
cmd="$cmd\""
id=$(eval $cmd)
