I have the following small script:
#!/usr/bin/env bash
packages_installed=($(apt-cache -q pkgnames | tr - _ | tr . _))
echo $packages_installed
if [ ${#packages_installed[@]} -eq 0 ]; then
echo "+unable_to_find_list_of_installed_packaged"
logger -p user.error -t find_installed_packages "$(hostname -f) was unable to determine list of installed packages using apt-cache"
else
for pkg in "${packages_installed[@]}"
do
echo "+installed_package_$pkg"
done
fi
Running this however prints:
root@olympus:~# sh test.sh
test.sh: 3: test.sh: Syntax error: "(" unexpected
This seems to indicate I've made a mistake on the line where I generate the installed package list. However I'm pretty sure that's how you get a command output into an array?
Feels like I'm missing something dumb.
