I’m encountering an issue where a command (a drush profile, to be exact) needs to be run within a created directory automatically. I can’t find much advisement within the script itself running it as an argument, and the logic i’ve been instructed by my superiors seems to suggest this as the best approach.
Here is what the bash script does:
- It creates the directory structure and some Apache2 files for a Drupal install
- It creates a rudimentary Drush profile that is then used by the utility to
- Autoinstall Drupal and modules by running the alias “standardprofile” within a directory containing this profile file
The actual commands I use to run the script from Bash (full scripts below) are
cd /var/www/$DOMAINNAME-dev.$URL
eval "standardprofile"
The above lines don’t run the script (or anything past the first starting line, and then then bash script resumes) Is there a better way to instruct a bash script to run a command from the specified directory and then resume once any other utilities being run in the foreground finish?
#!/bin/bash
# Creates the proper staging and development environment for a site
# Init
URL=example.com #URL used in creating directories
OMIT_STAGING="n" #Set to true if omitting staging

Is there a better way to instruct a bash script to run a command from the specified directory and then resume once any other utilities being run in the foreground finish?
Sure:
will run cmd from the specified directory. Since the two commands are run in a subshell, the script will resume in its present directory when the subshell completes.
