Linux wget, how to display progress percentage after session has reload

It sounds like you entered the wget command directly into the Start->Run dialog. If that's the case, you want to do this to move it to your Desktop:

1. Start->Run, enter cmd, press ENTER.

2. Check that the file is there: dir lang2.JPG (should output the file details). If you don't see the file listed, run dir to get a full listing of the directory in case you've misspelled it (or wget didn't name it what you expected).

3. Move it into the Desktop: move lang2.JPG Desktop

This all assumes that the wget command that you ran executed in the same directory that the command window opens in. Step 2 should prove that one way or the other.

If you don't see the file listed in Step 2, you'll need to resort to using Windows Search, or redownload it (open a command window first this time!).

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

Explanation:

• tar tarball tool
• cf create file
• - use stdout instead of a file (to be able to pipe the output to the next command)
• /folder-with-big-files The input folder to zip
• -P use absolute paths (not necessary, see comments)

pipe to

• pv progress monitor tool
• -s use the following size as the total data size to transfer (for % calculation)
  • $(...) evaluate the expression
  • du -sb /folder-with-big-files disk usage summarize in one line with bytes. Returns eg 8367213097 folder-with-big-files
  • pipe (|) to awk '{print $1}' which returns only the first part of the du output (the bytes, removing the foldername)

pipe to

• gzip gzip compression tool
• big-files.tar.gz output file name
