I also just tested a workaround using the bash builtin command "exec".
I put the following lines at the beginning of my script :
if [[ ! "$EXEC" ]]
then
export EXEC=1
exec -a myscript /bin/bash "$0" "$@"
fi
Then, on a common UNIX / Linux system, "ps -ef" gives something like this :
bobby 20326 20318 0 10:21 ? 00:00:00 myscript ./myscript.sh
marty 20330 20342 0 10:23 ? 00:00:00 myscript ./myscript.sh
dudul 20339 20363 0 10:25 ? 00:00:00 myscript ./myscript.sh
Perfect.
But on Cygwin, it still gives this :
bobby 20326 20318 0 10:21 ? 00:00:00 /usr/bin/bash
marty 20330 20342 0 10:23 ? 00:00:00 /usr/bin/bash
dudul 20339 20363 0 10:25 ? 00:00:00 /usr/bin/bash
I would have liked to see "myscript" instead of "/usr/bin/bash"...
Could ps command be corrected / improved to display "myscript" and/or command
line arguments ?
Or perhaps there is another solution ?
Thank you very much,
Best regards,
Ben
