note the unconverted path between double-quotes :
"C:/Program Files/Hummingbird/Connectivity/7.00/Accessories/"
I saw this problem on msys, I think it applies to cygwin as well.
If you just go into environment under advanced system settings in
control panel and remove the double quotes, it will work correctly. I'm
on Windows 7.
don't be kidding ! ok, I'm joking...
I'm reporting a cygwin bug...
of course I know I could edit the windows environment variables.
however, this problem has to be fixed.
also, how about to get rid of final slashes (.../ => ...) ?
You could reprocess your PATH in your .bashrc, but the final slashes
should have no effect on how the PATH is actually used...
everything is possible at shell level, even more efficiently, but since
the path is working by the cygwin layer, why not to clean things up.
PS : no fork cleanups...
# space tab newline
_IFS=${IFS:-'
'}
IFS=':'
# clean up final /'es
_PATH= _sep=
for _path in $PATH; do
case $path in */) _path=${_path#/} ;; esac
_PATH=${_PATH}${_sep}${_path}
_sep=':'
done
PATH=${_PATH}
# cleanup twins
_PATH= _sep=
for _path in $PATH; do
case ":${_PATH}:" in
*":${_path}:"*) ;;
*) _PATH=${_PATH}${_sep}${_path}; _sep=':' ;;
esac
done
PATH=${_PATH}
# not necessary, but...
# cleanup windows paths w/ space
_PATH= _sep=
for _path in $PATH; do
case ":${_path}:" in
*' '*) ;;
*) _PATH=${_PATH}${_sep}${_path}; _sep=':' ;;
esac
done
PATH=${_PATH}
IFS=${_IFS}
unset _IFS _PATH _path _sep
untested but should work...
of course, you may do this in one loop only !
also, I reworked my version of ssh-session-env.sh
