Custom wget output

Shell Programming and Scripting

The below hides the messy commands of wget 

#!/bin/bash

cd 'C:\Users\cmccabe\Desktop\wget'
wget -O getCSV.txt http://172.24.188.113/data/getCSV.csv
    progressfilt ()
{
    local flag=false c count cr=$'\r' nl=$'\n'
    while IFS='' read -d '' -rn 1 c
    do
        if $flag
        then
            printf '%c' "$c"
        else
            if [[ $c != $cr && $c != $nl ]]
            then
                count=0
            else
                ((count++))
                if ((count > 1))
                then
                    flag=true
                fi
            fi
        fi
    done
}

output of the command:

Is it possible to have:

Thank you :).

This is close with the text in bold missing (can they be added in the code):

 wget -O getCSV.txt http://xxx.xx.xxx.xxx/data/getCSV.csv --progress=bar:force 2>&1 | tail -f -n +6

Filtering interactive things is always difficult. wget has something similar, however. Try wget -nv for less-verbose output which still has a progress bar -- much less messy.

Is it possible to do something like this:

#!/bin/bash

cd 'C:\Users\cmccabe\Desktop\wget'
wget -O getCSV.txt http://xxx.xx.xxx.xxx/data/getCSV.csv

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"
}

Output on screen:

Downloading: getCSV.csv: %

wget -q --no-progress url

Fiddle with --progress= to fine tune it, see man wget.

Thank you :).

Er, typo. --show-progress, not --no-progress.
