Programming :: Progress Bar Instead Of Percentage Complete For Loop

Nov 25, 2010

I've got a loop which is able to echo out how complete a process is after each loop (e.g says 25% if the loop has 4 elements and has run once through). Is there any way I can print characters, perhaps a progress bar? I was thinking of using the percentage as a count or something and using.

I got told off for including code from work here.

Programming :: Cannot Capture SCP Progress Bar In Output Redirect

Oct 31, 2010

I would really like to capture the output of scp and my file's progress. Scp updates the transfer rate every 1 second, and I will like to save the transfer rate at every update. So for example, if the file transfer takes 30 seconds, I would like 30 reports of the transfer rate.

The output looks like:
file.dat 1% 3664KB 938.5KB/s 05:48

Whenever I try a simple redirect like:
scp file.dat &> output
... it does not save the rate at every update, it only shows the final rate.

If I try using typescript by starting "script" ... it's the same deal.

Programming :: Rsync Bash Script With Progress Bar?

Apr 26, 2009

I'm writing a script to automate rsync backups which so far is working great. I prefer to send output to a text file instead of watching it fly by but the blank output is slightly boring? I would love to use a progress bar. Not for each file but for overall progress. Something like

syncing /home directory 50% [++++++++]

I already know it's way over my head and maybe bash isn't even the right tool for the job.

Programming :: How To Get Zenity Progress Bar Working Properly

Apr 14, 2011

I am busy writing this script to get a pixel count of a large batch of images in a directory for a research project. To do this I'm using a loop to get all the images in the directory. To make the whole procedure more user friendly for some colleagues I decided to use zenity, something I haven't yet really worked with. As not to make sure that the users don't have to watch to this blank screen during the actual processing of the images I'm trying to get the zenity progress bar working. So far the progress bar comes up but instead of changing over time it stays "empty" till all the images are processed and then becomes 100% when all images are done. What servers my needs for now, but since I am trying to learn more about zenity I was wondering how I could change the script to get the progress bar properly working? Below is the piece of script I am talking about.

cd $input #goto path of image directory
(for a in *jpg *JPG *jpeg *JPEG; do
if [ -f "$a" ]; then #was it a image file
b="$a" #set b to $a
convert -resize 1000x1000! ${b} -depth 1 -format %c histogram:info:$b.txt #get pixelcount and write to .txt file
done) | zenity --progress

Programming :: SED Processing - Export Progress Bar From Wget Display

Nov 2, 2010

I am attempting to "export" the progress bar from wget display using sed. Basically, we have an app that starts wget to download a large file and we want to show a progress bar. Our application has a dbus interface to receive the download progress.

So we were think of a command like:
wget [] | sed [] | dbus-send[]
The problem at the moment is, how do you get the matched string out of sed and into dbus-send? I can get the progress string by:
sed -u 's/[0-9]*%/&/'

This populated '&' with the correct percentage, but I cannot seem to get this out of sed.

Programming :: Custom Progress Bar Of Video Conversion Script (FLV To XVID)

Aug 7, 2010

i have written a bash script to convert flv files (e.g. videos) to xvid to be played on my dvd player. the conversion is not really the issue, as it works. what i am dealing with now are 2 problems i have not found a good workarouond:
1. surpressing the shell output of mencoder completely ( i do not want to see all the mencoder messages). this i have only solved to a certain extend.
2. i want to create a progress bar. this one i have not yet cracked.

the script:
## settings
video_opts="-ovc xvid -xvidencopts bitrate=$v_bitrate:autoaspect"
audio_opts="-oac mp3lame -lameopts fast:preset=standard"
store_dir=./converted_files .....

#start the script
1. mencoder output: using /dev/null works more or less. for example: if mencoder detects a double frame while converting, a message is still printed on the bash screen
2. progressbar: i have no clue yet on how to do this. any link or tip is welcome.
my goal is something like this:
[56%] [time in progress] [timeleft]

General :: Shell Programming Using While Loop

Jun 28, 2010

I am trying to do some shell programs. I tried some sites regarding the while loop, they give the structure as:
while [ n1 -lt 500 ]
echo $((n1+100))

But the below code also worked for me:
while ((n1 > 500))
echo $((n1+100))
By using (( )) I could use while, for. But the documentations didnt follow this way. I mainly use this for datastructure programming.

Programming :: Error Codes In A For Loop

Nov 3, 2010

I've got a 'nested' for loop which has a grep in it, if the grep fails there's no output - however the error code is still $0 and the second for loop is still entered, there's also a grep in the second for loop.I guess ultimately what i need to know is whether there's a way of making grep generate an error code. when no results are found?

Programming :: Bash For Loop - All Responses On One Line

Nov 18, 2010

I'm writing a mass snmp toner check which polls any toners available to be snmp polled, however when using a loop statement I get the results on different lines; which sounds good, however the tool I use to check with (nagios) ignores the new lines.

Is there any way I can get the output on one line? Also, I need to raise a fault if any of the toners are below a specific level (with nagios you raise faults with the exit code) - any way I can do this without exiting the loop. Code below with bits and bobs commented out.

check_ink_levels ()

Programming :: Pass Arguments To A Function Using A Loop

Mar 1, 2010

I need to pass a large number of arguments to a function which takes variable number of arguments, such as gtk_list_store_new. But it doesn't look nice if i write something like gtk_list_store_new(NUM,TYPE_A,TYPE_B,TYPE_C,...,TYPE_OMEGA); because of large number of arguments. And, it will be a trouble to change number of columns because of need to manually change arguments to large number of such functions. So, how can i pass all the arguments to a function using a loop? Something like


Of course, i could just use asm code for this, but is there a portable way of doing so?

P.S. i mean C language.

Programming :: Imagemagick With For Loop On The Commandline Does Not Work

May 26, 2011

I have images in jpg format



I used imagemagick to convert the files to gif with the following command


for i in {100..131}; do convert CIMG0$i.jpg CIMG0$i.gif; done # works

This worked like expected, but when afterwards I wanted to scale the images


for i in {100..131}; do convert -scale 25% CIMG00$i.gif CIMG00$i_scaled.gif; done # works not it seems the system is working for about half a minute, but I get no output. The single command


convert -scale 25% CIMG100.gif CIMG100_scaled.gif # works

works as expected and gives me a scaled image. What does the convert command do in the second case? is the for-loop wrong?
