This isn't really a cygwin question; there are lots of shellscripting
tutorials on the web, which I recommend you look for. Meanwhile,
however, try this:
#!/bin/bash
function usage
{
echo >&2 "Usage: $0 [-h|-l loops|-m max_ms|-o offset_ms|-r ramp|-t threads]"
exit $1
}
# default values
loops=2
max_ms=100
offset_ms=89900
ramp=1
threads=4
while getopts 'hl:m:o:r:t:' opt; do
echo opt=$opt
case "$opt" in
h) usage 0;;
l) loops="$OPTARG";;
m) max_ms="$OPTARG";;
o) offset_ms="$OPTARG";;
r) ramp="$OPTARG";;
t) threads="$OPTARG";;
?) usage 1;;
esac
done
shift $(( OPTIND - 1 ))
if (( $# )); then
usage 1
fi
ssh localhost 'cd /cygdrive/c/apps/bin && LOOPS="'"$loops"'"
MAX_MS="'"$max_ms"'" OFFSET_MS="'"$offset_ms"'" RAMP="'"$ramp"'"
THREADS="'"$threads"'" nohup ./start.sh & ps -efW | grep java'
That ssh command should be all on one line. Careful with the
sequences of quotation marks. The idea is to build a command string
that includes literal quotation marks intermixed with the quoted
expansion of local variables.
Also note that if all you're looking to getting out of that ps |grep
java line is the PID, you can just use $!.
