i need to free some space on my juniper router , in the root directory when i use >ls -lash command i see a .tgz file which is 405 M , my question , if i delete this will it cause any problem ?
Juniper built a specific command for cleaning up files.
request system storage cleanup and
request system storage cleanup dry-run
The documentation is here, but basically it's for doing exactly what you want - deleting unnecessary files. I tend to just use
dry-run and manually delete a handful if I'm even slightly concerned about it. While it's a bit liberal, it will never delete anything critical to the system.
