Simple runwin32 launcher for Cygwin+rsh

runwin32.sh

#!/bin/sh

# Note:
# - Environment variables must be set before running. This script doesn't import any user profiles.

# Add Windows system directory paths to the PATH,
# to allow to use cmd.exe and any other standard commands.
export PATH="$(cygpath -S):$(cygpath -W):$PATH"

# Add some common system variables.
#
# You may want this section, only if you're running the script via remote shell,
# since the rsh daemon doesn't import Windows environment variables at all.
#[ ! -v COMPUTERNAME ] && export COMPUTERNAME="$(hostname)"
#[ ! -v SYSTEMDRIVE ]  && export SYSTEMDRIVE="$(cygpath -w -W | cut -f1 -d '\')"
#[ ! -v TEMP ]         && export TEMP="$(cygpath -w -F 0x001c)\Temp"
#[ ! -v TMP ]          && export TMP="$TEMP"
#[ ! -v USERNAME ]     && export USERNAME="$(id -un)"
#[ ! -v USERPROFILE ]  && export USERPROFILE="$(cygpath -w -F 0x0028)"

# Run specified command line.
# Piped by cat, otherwise remote shell will output corrupted text.
#
# Known Issue:
# When Cygwin launches a Win32 process, its arguments are escaped by MSVC escaping rule.
# Thus, commands which follow an another escaping rule may get unexpected value.
#
# For example, built-in shell commands (such as dir) doesn't follow MSVC escaping rule.
# `dir "C:\Program Files\"` will get replaced by dir `"C:\Program Files\\"`
# and such a conversion sometimes may cause an error.
