I have a couple of big files that I would like to compress. I can do this with for example
tar cvfj big-files.tar.bz2 folder-with-big-files
The problem is that I can't see any progress, so I don't have a clue how long it will take or anything like that. Using v
I can at least see when each file is completed, but when the files are few and large this isn't the most helpful.
Is there a way I can get tar to show more detailed progress? Like a percentage done or a progress bar or estimated time left or something. Either for each single file or all of them or both.
Answer
I prefer oneliners like this:
tar cf - /folder-with-big-files -P | pv -s $(du -sb /folder-with-big-files | awk '{print $1}') | gzip > big-files.tar.gz
It will have output like this:
4.69GB 0:04:50 [16.3MB/s] [==========================> ] 78% ETA 0:01:21
For OSX (from Kenji's answer)
tar cf - /folder-with-big-files -P | pv -s $(($(du -sk /folder-with-big-files | awk '{print $1}') * 1024)) | gzip > big-files.tar.gz
