The problem is same if I use dot

abc@alpha:/scratch2/abc/Xilinx/Petalinux$ ./settings.sh
bash: ./settings.sh: Permission denied

I also have tried with source. Still it complaint for bash.

abc@alpha:/scratch2/abc/Xilinx$ source Petalinux/settings.sh

When I run the "chsh -s /bin/bash" to change shell to bash. I get the following issue.

abc@alpha:/scratch2/abc/Xilinx$ chsh -s /bin/bash

chsh: user 'abc' does not exist in /etc/passwd

you need make the file executeable. Run:

sudo chmod +x settings.sh

then try running it again:

./settings.sh

Alternatively you can run it without making it executebale by passing it to bash:

bash setting.sh
