Shell script not running, "No such file or directory"

Question

I was following the procedure from Relsense SDK 2.0 Guide on installing librealsense to Ubuntu 22.04.5 https://dev.intelrealsense.com/docs/compiling-librealsense-for-linux-ubuntu-guide to install the librealsense. Though I was stuck at second step,

./scripts/setup_udev_rules.sh

but it only gives me this:

bash: ./scripts/setup_udev_rules.sh: No such file or directory

I suspected it was a problem with permission, and tried adding permission with this command chmod +x /path/to/yourscript.sh, though it didn't change anything.

PS: I ran

ls -l scripts/setup_udev_rules.sh

and gave me this

ls: cannot access 'scripts/setup_udev_rules.sh': No such file or directory

I have been stuck on this problem for quite awhile by now, so any comments on this would be appreciated.

• choroba: Add the output of ls -l scripts/setup_udev_rules.sh.
• Benjamin W.: Did you switch into the librealsense directory first? That step is only implicit in the instructions.
• Barmar: Why would you think changing permissions would help? The error message says the file doesn't exist, not that permissions are wrong.
• Shunsuke Honjo: Thanks @BenjaminW. that solved the problem. I really appreciate this!
• Barmar: You should report this to the developers, it really should be in the instructions.
