How can Bash execute a command in a different directory context

Question

I have a common command that gets called from within very specific directories  There is only one executable sitting in  bin for this program  and the current working directory is very important for running it correctly  The script affects the files that live inside the directory it is run within   Now  I also have a custom shell script that does some things in one directory  but I need to call that command mentioned above as if it was in another directory   How do you do this in a shell script

Use cd in a subshell  the shorthand way to use this kind of subshell is parentheses    cd wherever  mycommand        That said  if your command has an environment that it requires  it should really ensure that environment itself instead of putting the onus on anything that might want to use it  unless it s an internal command used in very specific circumstances in the context of a well defined larger system  such that any caller already needs to ensure the environment it requires    Usually this would be some kind of shell script wrapper

You can use the cd builtin  or the pushd and popd builtins for this purpose  For example     do something with  etc as the working directory cd  etc      do something with  tmp as the working directory cd  tmp     You use the builtins just like any other command  and can change directory context as many times as you like in a script
