Why does a shell script need current directory?

[Peng Yu]

Hi,

I run the following script in a directory that is deleted (on Mac OS
X). I see then the following error. Why does bash need to access the
current directory? Thanks.

$ cat /tmp/main.sh
#!/usr/bin/env bash
$ /tmp/main.sh
shell-init: error retrieving current directory: getcwd: cannot access
parent directories: No such file or directory
