The terminal solution would look like ssh user@host 'cd /path/ && tar -cf - file | gzip -9' > file.tgz
(or actually <filedescriptor>
instead of file.tgz
). The first part of that (the ssh stuff) is nicely wrapped in the DSL; right now I only see support for it while using a custom ssh command
.
Scenario is to create
tgz
archives on a remote server (tar -czf --to-stdout directory
). Currently,capture
ing the output will be done in memory which is not feasible for large output. Implementation could be specific for files (likecapture %Q{tar czf -O}, into_file: 'bigarchive.tgz'
) or preferrably more general (capture %Q{}, into_io: File.open(...)
).With a bit of headwrapping, this could also be modelled as
download_cmd_out tar_cmd, to: 'stdout.file'
.Note that while i refer to
tar
commands, this might be useful for other commands that produce a lot of data, too.
