How to show wget progress bar only?

For example:

wget http://somesite.com/TheFile.jpeg

downloading: TheFile.tar.gz ...
--09:30:42--  http://somesite.com/TheFile.jpeg
           => `/home/me/Downloads/TheFile.jpeg'

How can i get it to look like this

downloading: TheFile.jpeg ...

I know curl can do that, however i need to get wget to do that job.

You can use the following filter:

progressfilt ()
{
    local flag=false c count cr=$'\r' nl=$'\n'
    while IFS='' read -d '' -rn 1 c
    do
        if $flag
        then
            printf '%s' "$c"
        else
            if [[ $c != $cr && $c != $nl ]]
            then
                count=0
            else
                ((count++))
                if ((count > 1))
                then
                    flag=true
                fi
            fi
        fi
    done
}

Usage:

$ wget --progress=bar:force http://somesite.com/TheFile.jpeg 2>&1 | progressfilt
100%[======================================>] 15,790      48.8K/s   in 0.3s

2011-01-13 22:09:59 (48.8 KB/s) - 'TheFile.jpeg' saved [15790/15790]

This function depends on a sequence of 0x0d0x0a0x0d0x0a0x0d being sent right before the progress bar is started. This behavior may be implementation dependent.

Use:

wget http://somesite.com/TheFile.jpeg -q --show-progress

-q - Turn off Wget's output

--show-progress - Force wget to display the progress bar in any verbosity

回答3:

Use using these flags:

wget  -q --show-progress --progress=bar:force 2>&1

回答4:

The option --show-progress, as pointed out by others, is the best option, but it is available only since GNU wget 1.16, see Noteworthy changes in wget 1.16.

To be safe, we can first check if --show-progress is supported:

# set progress option accordingly
wget --help | grep -q '\--show-progress' && \
  _PROGRESS_OPT="-q --show-progress" || _PROGRESS_OPT=""

wget $_PROGRESS_OPT ...

Maybe it's time to consider just using curl.

回答5:

You can use the follow option of tail:

wget somesite.com/TheFile.jpeg --progress=bar:force 2>&1 | tail -f -n +6

The +6 is to delete the first 6 lines. It may be different on your version of wget or your language.

You need to use --progress=bar:force otherwise wget switches to the dot type.

The downside is that the refreshing is less frequent than with wget (looks like every 2 seconds). The --sleep-interval option of tail seems to be meant just for that, but it didn't change anything for me.

回答6:

You can use standard options:

wget --progress=bar http://somesite.com/TheFile.jpeg

回答7:

This is another exemple, maybe will help you

download() {
    local url=$1
    echo -n "    "
    wget --progress=dot $url 2>&1 | grep --line-buffered "%" | sed -u -e "s,\.,,g" | awk '{printf("\b\b\b\b%4s", $2)}'
    echo -ne "\b\b\b\b"
    echo " DONE"
}

回答8:

Here is a solution that will show you a dot for each file (or line, for that matter). It is particularly useful if you are downloading with --recursive. This won't catch errors and may be slightly off if there are extra lines, but for general progress on a lot of files it is helpful:

wget -r -nv https://example.com/files/ | \
    awk -v "ORS=" '{ print "."; fflush(); } END { print "\n" }'

回答9:

This is not literally an answer but this snippet might also be helpful to some coming here for e.g. "zenity wget GUI":

LANG=C wget -O /dev/null --progress=bar:force:noscroll --limit-rate 5k http://nightly.altlinux.org/sisyphus/ChangeLog 2>&1 | stdbuf -i0 -o0 -e0 tr '>' '\n' | stdbuf -i0 -o0 -e0 sed -rn 's/^.*\<([0-9]+)%\[.*$/\1/p' | zenity --progress --auto-close

What was crucial for me is stdbuf(1).
