Progress bar

trickydba · 01-13-2017, 02:34 PM

I have a script that compresses either Jan-Jun folders that contain reports or Jul-Dec. I would like to incorporate a progress bar. Any help is highly appreciated. This is my code:

Code:

#!/bin/bash

OPTION=$(whiptail --title "Multi-Folder Compressor - By Me " --menu "Choose the month range to compress" 15 60 4 \
"1" "January to June" \
"2" "July to December" \
"3" "FUTURE"  3>&1 1>&2 2>&3)

YEAR=$(whiptail --inputbox "Please input the year" 10 30 3>&1 1>&2 2>&3)

#Actions to take based on selection
case $OPTION in
    1) echo "Compressing folders Jan to Jun "; find . -type d \( -name "01*" -o -name "02*" -o -name "03*" -o -name "04*" -o -name "05*" -o -name "06*" \) | xargs tar -zcvf /export/dir/dir/reports/dir/dir/JanJun${YEAR}.tar.gz;;
    2) echo "Compressing folders Jul to Dec "; find . -type d \( -name "07*" -o -name "08*" -o -name "09*" -o -name "10*" -o -name "11*" -o -name "12*" \) | xargs tar -zcvf /export/dir/dir/reports/dir/dir/JulDec${YEAR}.tar.gz;;
    3) echo "For future use....closing ";;
    4) echo "This option is disabled ";;
    *) invalid option;;

Although I've never tried this, it was designed to show dd progress, dd was replaced with tar in the code below.

Code:

ps ux | awk '/bin\/tar/ && !/awk/ {print $2}' | xargs kill -s USR1 $1

Where do I plug this in my code?

I am looking to incorporate something like this example in my code:

Code:

#!/bin/bash
PCT=0
(
while test $PCT != 100;
do
PCT=`expr $PCT + 10`;
echo $PCT;
sleep 1;
done; ) | whiptail --title "GAUGE" --gauge "Hi, this is a gauge widget" 20 70 0

You can use the pv command to pass values to whiptail but if you want something realistic you need to find the total size of all directories to be tarred via the du command.

Here is an example using pv to monitor progress without whiptail.

Code:

find . -type d \( -name "01*" -o -name "02*" -o -name "03*" -o -name "04*" -o -name "05*" -o -name "06*" \) | pv  -s total_number_of_bytes | xargs tar -zcvf file_name.tgz

Untested but something like this might work

Code:

find . -type d \( -name "01*" -o -name "02*" -o -name "03*" -o -name "04*" -o -name "05*" -o -name "06*" \) | (pv  -n -s no_of_bytes | xargs tar -zcvf testme.tgz) | whiptail --title "GAUGE" --gauge "Hi, this is a gauge widget" 20 70 0

This 'pv', is this something that comes with the install or I have to get it installed?
Where do I incorporate this in my script?
I'm want to add this in my script mainly to shine it up a bit. To make it look like I know what I'm doing, LOL.

Should be installed. My example was complete for taring jan-Jun files

trickydba · 01-17-2017, 09:01 AM

@michaelk......Where do I exactly plug in this code?

michaelk · 01-17-2017, 09:02 AM

Your option 1

trickydba · 01-17-2017, 09:45 AM

I plugged in your suggested code, and it ran, but after selecting the option and inputting the year nothing happens. The script stops. Here is the actual code:

Code:

#!/bin/bash

OPTION=$(whiptail --title "Multi-Folder Compressor - By Me " --menu "Choose the month range to compress" 15 60 4 \
"1" "January to June" \
"2" "July to December" \
"3" "FUTURE"  3>&1 1>&2 2>&3)

YEAR=$(whiptail --inputbox "Please input the year" 10 30 3>&1 1>&2 2>&3)

#Actions to take based on selection
case $OPTION in
        1) find . -type d \( -name "01*" -o -name "02*" -o -name "03*" -o -name "04*" -o -name "05*" -o -name "06*" \) | (pv  -n -s no_of_bytes | xargs tar -zcvf /dir1/dir2/dir3/dir4/dir5/reports/JanJun${YEAR}.tar.gz) | whiptail --title "GAUGE" --gauge "Hi, this is a gauge widget" 20 70 0

        2) find . -type d \( -name "07*" -o -name "08*" -o -name "09*" -o -name "10*" -o -name "11*" -o -name "12*" \) | (pv  -n -s no_of_bytes | xargs tar -zcvf /dir1/dir2/dir3/dir4/dir5/reports/JanJun${YEAR}.tar.gz) | whiptail --title "GAUGE" --gauge "Hi, this is a gauge widget" 20 70 0

        3) echo "For future use....closing ";;
        4) echo "This option is disabled ";;
        *) invalid option;;

esac

I thought it would be because there wasn't ";;" after option 1 and 2 but that did nothing.

insert set -xv at the beginning of your script and you will see what's happening (this will not solve anything, just print variables and program flow).

trickydba · 01-17-2017, 10:29 AM

Says a ")" is missing but I don't see one missing

michaelk · 01-17-2017, 04:00 PM

I did mislead you in the fact that what I posted was not working code. As stated to be a meaningful percentage you need to find the number of bytes to be tarred. The following might work as an approximation.

Code:

bytes=$(find . -type d \( -name "01*" -o -name "02*" -o -name "03*" -o -name "04*" -o -name "05*" -o -name "06*" \) -exec du -cb {} + | grep total$ | awk '{print $1}')

That is your no_of_bytes variable for your script. As an exercise can you add the above into your script?

trickydba · 01-18-2017, 10:52 AM

@michaelk.....After inputting your code:

Code:

echo "Compressing folders Jan to Jun "; bytes=$(find . -type d \( -name "01*" -o -name "02*" -o -name "03*" -o -name "04*" -o -name "05*" -o -name "06*" \) -exec du -cb {} + | grep total$ | awk '{print $1}')

I get this error:

Code:

./compressfolderfinal: line 13: syntax error near unexpected token `)'
