|
|
|
|
- name: Change the working directory to somedir/ before executing the command
|
|
ansible.builtin.shell: somescript.sh >> somelog.txt
|
|
args:
|
|
chdir: somedir/
|
|
|
|
# You can also use the 'args' form to provide the options.
|
|
- name: This command will change the working directory to somedir/ and will only run when somedir/somelog.txt doesn't exist
|
|
ansible.builtin.shell: somescript.sh >> somelog.txt
|
|
args:
|
|
chdir: somedir/
|
