Just an FYI. Chris's script is executed as a child/sub-process. Downside to that is your main code can hang reading a site and Chris's spinner will still be spinning away. My script was using a for loop to emulate your loop of reading sites. My ls > /dev/null was a replacement of your fetching/processing web site contents and allow you to see the spinner/wheel actually spinning.

I have tried by placing another for loop in my script. It keeps on failing. Here is the script #!/bin/bash if [ -z "$1" ] then printf "Provide the text file location to process.\n" exit 0 fi _wheel="|/-\\" _c=0 _counter=0 printf "Browsing URLs." for i in {1..100} ; do printf "\010%s" ${_wheel:$_c:1} let _c="_c + 1" if [ $_c -gt 3 ] ; then _c=0 fi let _counter="_counter + 1" if [ $_counter -gt 10 ] ; then _counter=0 printf "\010.|" fi done { for j in `cat $1` do echo "$j - `HEAD -d $j`" done } > "/tmp/output.text" 2>&1 printf "\n" It is showing only Browsing URLs.........\ My input text file contains 600+ urls. Does the progress bar will show until the script process all of my URLs? can you please fix my problem. |
