Why does my shell script (web server) node suddenly not work?
I have a .launch file that launches various nodes. This has previously worked great but recently I must have changed something as it no longer launches my web server .sh script correctly.
I believe the script is fine because I can run this independently of ROS. However, when running it using rosrun I get errors suggesting that no commands are recognised including source and cd, i.e. not just ROS commands like roscd.
Could anybody suggest what I may have done to break this? Maybe something in the wider ROS system/install?
could you share a minimum, not-working example such that we better understand your issue and can try to reproduce?
