Here's a fancy progress bar that you might enjoy...

You can use pv but the other way.

 for ... # outer loop
 do
   ...
   echo -n X
 done | pv -s $(wc -l 'your_file_list') - >/dev/null

so you use echo X to say when another portion of work is done and this is counted by pv, it's know what the whole job size is due to -s option.

Solution 3

You could use something like:

progress(){
    # example usage:
    # progress 30G 9G 30
    # 30G [================>.................................] 30% (9G)

    # params:
    # $1 = total value (e.g.: source size)
    # $2 = current value (e.g.: destination size)
    # $3 = percent completed
    [[ -z $1 || -z $2 || -z $3 ]] && exit  # on empty param...

    percent=$3
    completed=$(( $percent / 2 ))
    remaining=$(( 50 - $completed ))

    echo -ne "\r$1 ["
    printf "%0.s=" `seq $completed`
    echo -n ">"
    [[ $remaining != 0 ]] && printf "%0.s." `seq $remaining`
    echo -n "] $percent% ($2)  "
}

You can see an usage example in https://github.com/ivanalejandro0/misc/blob/master/shell-scripts/copy-progress.sh

Solution 4

Change the outer loop to:

pv /var/www/vhosts/domainlist | while read f
do
    ...
done

http://linux.die.net/man/1/pv

Or you can use any other program that provides a progress bar based on how much a file has been read.

Solution 5

Given that you mentioned in a comment that you're on a debian based system, you could use whiptail. When you install a deb package that requires configuration, text-based windows are drawn to ask you stuff; that's whiptail.

Something like

#!/usr/bin/env bash

# mapfile requires bash 4
mapfile -t domains < /var/www/vhosts/domainlist

# for older bash versions, read can be used in this case.
#IFS=$'\n' read -rd '' -a domains < /var/www/vhosts/domainlist

n=${#domains[@]}

for ((i=0; i < n; ++i)); do
    printf 'XXX\n\n%s\nXXX\n' "Checking ${domains[i]}"
    if whois "${domains[i]}" | grep -Fiq domainregistrar; then
        printf '%s\n' "${domains[i]}" >&3
    else
        printf '%s\n' "${domains[i]}" >&4
    fi
    printf '%d\n' $((100*i/n))
done 3>our_registrar 4>external_registrar | whiptail --gauge "" 6 50 0

I'm using the following script to go through a large list of domains in whois and find the registrar (useful for server/DNS migrations) and it works fine.

However I am wanting to incorporate a progress bar into it just for the sake of convenience. Here's my script, if it can be improved let me know:
```
#!/bin/bash
for f in `cat /var/www/vhosts/domainlist`
 do
   if
   domain=$f
   [ "$domain" ] ;
   then
    whois $f | grep -i domainregistrar > /dev/null
     if
     [ $? -le 0 ] ;
     then
      echo $f >> our_registrar
     else
      echo $f >> external_registrar
     fi
   fi
 done
echo "Done, check our_registrar file."
```
I've tried this first: http://moblog.bradleyit.com/2010/02/simple-bash-progress-bar-function.html

And then this but with no luck.

What do you reckon is the easiest way to get a progress bar implemented into that script?

Forgot to say, (not sure if relevant), on an Ubuntu 10.04 box with only SSH, no GUI. Those seem directed towards ones with a GUI, however I imagine due to it being unix it all applies down to SSH anyway.

OK, then the pv is optimal solution.

I placed that line in it, the script still works however it goes to 100% with the bar full immediately: ./findregistrar.sh 1.12kB 0:00:00 [30.4MB/s] [===========================================================‌====================‌‌==================‌=>] 100% so it has not worked correctly. It sits at the blank cursor which is normal until completed, then when done obviously it says: Done, check our_registrar file. But not clear on why it is not working.

I have a feeling it is due to it not knowing what 25/50/75/100 is actually defined by and when it has reached a % stage.

It's probably because bash's read read whole input and then process it.

Would it help if I got it to calculate how many lines are in the file, divide this by 10 and tell it when =>X (or <=X ) amount of lines has completed, that is 10% and do a line count/check and then once it has completed each line get it to say "complete".

I shall have a look at this when I get home :) Cheers so far.

bash v4 is required for mapfile.

@jordanm, good point. I'm fairly certain Ubuntu 10.04 has bash 4, but I updated the answer with an alternative for older bash versions anyway.

Yes, looks like it has 4.1: packages.ubuntu.com/lucid/bash

I get a strange unicode-sign at the top-left corner for the %: % PLEASE WAIT WHILE SCRIPT IS IN PROGRESS how can I remove that? screenshot: i.stack.imgur.com/7JHnj.png

I think I solved it with changing DRAW to just DRAW(){echo -en "\033(0";} What was the echo -en "\033%"; for?

This is pretty neat, but bear in mind that it puts the for-loop in a subshell, and so any changes you make to variables inside the loop won't affect variables outside the loop!
