    calculating write speed

    Here is my latest try that works
    EXCEPT
    (1)wild card * asterisk not allowed in source folder
    (2)also you have to mention device name in target - nothing else
    (3)check the locaion of bash before running script
    Code:
    #!/usr/bin/bash
    	counter=0
    	sum=0
    	which bc 2> /dev/null
    	if [ "$?" -eq 1 ]
    	then
    		mode="simple"
    	else
    		mode="accurate"
    	fi	
    echo we began at $(date)
    monitor_drive=sdb1
    number_of_argument=$#
    if [ "$1" = "--help" ]
    	then
    	echo USAGE
    	echo "./smartcopy.sh source-dir <sd##>"
    	we assume sdb1
    	exit
    fi
    full_command=$@
    #echo $full_command
    if [ "$number_of_argument" -gt 2 ]
    	then
    	echo defaults overridden
    #	monitor_drive=$3
    	monitor_drive="${@: -1}"
    fi
    echo we-will-monitor-$monitor_drive
    mountpoint=$(df | grep -i $monitor_drive | awk '{ print $NF }')
    echo whose mount point is $mountpoint
    source_dest=$(echo $full_command | sed 's/ [[:alnum:]]*$//')
    echo we will run cp -r \"$source_dest\" $mountpoint
    cp -r "$source_dest" $mountpoint &
    processid=$!
    echo PID is $processid
    echo format is data-rate of last 10 seconds in KBps , MBps , average so far in KBps
    while true
    do
    	tzero=$(df | grep -i $monitor_drive | awk '{print $3}')
    	#echo  tzero is $tzero
    	sleep 10
    	tten=$(df | grep -i $monitor_drive | awk '{print $3}')
    	#echo  tten is $tten
    	diff=$((tten-tzero))
    	counter=$(($counter + 1))
    	#echo difference is $diff
    	if [ "$mode" = "simple" ]
    		then
    		mbps=$((diff/10240))
    		kbps=$((diff/10))
    		sum=$(($sum+$kbps))
    		avg=$(($sum/$counter))
    		echo -e "$kbps KBps , $mbps MBps\t$avg KBps"
    	else
    		mbps=$(echo "scale=2;$diff/10240"|bc -l)
    		kbps=$(echo "scale=0;$diff/10"|bc -l)
    		sum=$(echo "$sum+$kbps" | bc -l)
    		avg=$(echo "scale=0;$sum/$counter"|bc -l)
    #		echo -e "$kbps KBps , $mbps MBps\t$avg KBps"
    #		awk -v kbps=$kbps -v mbps=$mbps avg=$avg '{ printf "%-10s %-10s %-20s\n", kbps, mbps, avg}'
    		echo "$kbps $mbps $avg" | awk '{ printf "%-10s %-10s %-10s\n", $1, $2, $3}'
    	fi
    	if [ "$2" != "no" ]
    		then
    		kill -0 $processid 2> /dev/null
    		if [ "$?" -eq 1 ]
    			then
    			echo cp process complete/killed . Bye .
    			exit
    		fi
    	fi
    done
    echo we end at $(date)
    if [ -z "$SECONDS" ]; then echo "SECONDS variable not present so cannot report time elapsed"; else echo "time elapsed is '$SECONDS'"; fi

    calculating write speed

    here is updated one which gets rid of finding pid of process as copying process is started inside script
    Code:
    #!/bin/bash
    	counter=0
    	sum=0
    	which bc 2> /dev/null
    	if [ "$?" -eq 1 ]
    	then
    		mode="simple"
    	else
    		mode="accurate"
    	fi	
    echo we began at $(date)
    monitor_drive=sdb1
    number_of_argument=$#
    if [ "$1" = "--help" ]
    	then
    	echo USAGE
    	echo "./general source-dir target-dir <sd##>"
    	we assume sdb1
    	exit
    fi
    cp -r $1 $2 &
    if [ "$number_of_argument" -gt 2 ]
    	then
    	echo defaults overridden
    	monitor_drive=$3
    fi
    echo we-will-monitor-$monitor_drive
    mountpoint=$(df | grep -i $monitor_drive | awk '{ print $NF }')
    echo whose mount point is $mountpoint
    processid=$!
    echo PID is $processid
    echo format is data-rate of last 10 seconds in KBps , MBps , average so far in KBps
    while true
    do
    	tzero=$(df | grep -i $monitor_drive | awk '{print $3}')
    	#echo  tzero is $tzero
    	sleep 10
    	tten=$(df | grep -i $monitor_drive | awk '{print $3}')
    	#echo  tten is $tten
    	diff=$((tten-tzero))
    	counter=$(($counter + 1))
    	#echo difference is $diff
    	if [ "$mode" = "simple" ]
    		then
    		mbps=$((diff/10240))
    		kbps=$((diff/10))
    		sum=$(($sum+$kbps))
    		avg=$(($sum/$counter))
    		echo -e "$kbps KBps , $mbps MBps\t$avg KBps"
    	else
    		mbps=$(echo "scale=2;$diff/10240"|bc -l)
    		kbps=$(echo "scale=0;$diff/10"|bc -l)
    		sum=$(echo "$sum+$kbps" | bc -l)
    		avg=$(echo "scale=0;$sum/$counter"|bc -l)
    #		echo -e "$kbps KBps , $mbps MBps\t$avg KBps"
    #		awk -v kbps=$kbps -v mbps=$mbps avg=$avg '{ printf "%-10s %-10s %-20s\n", kbps, mbps, avg}'
    		echo "$kbps $mbps $avg" | awk '{ printf "%-10s %-10s %-10s\n", $1, $2, $3}'
    	fi
    	if [ "$2" != "no" ]
    		then
    		kill -0 $processid 2> /dev/null
    		if [ "$?" -eq 1 ]
    			then
    			echo cp process complete/killed . Bye .
    			exit
    		fi
    	fi
    done
    echo we end at $(date)
    if [ -z "$SECONDS" ]; then echo "SECONDS variable not present so cannot report time elapsed"; else echo "time elapsed is '$SECONDS'"; fi
    if anybody interested then run
    ./script-name.sh source-folder destination-folder sd##
    sd##=the device where file is being copied(sdb1 default)


    THE DRAWBACK
    it expects folder-names without backslashes i.e alphanumeric only because $1 & $2 are space separated arguments.

    Can you help me solve this ?

    calculating write speed

    I am going to add time elapsed & average writing speed using concept from
    Code:
    #!/bin/bash
    count=1
    sum=0
    for i in 1 2 3 4 5
    do
       echo "Welcome $i times"
    sum=$(echo "$sum+$i"|bc -l)
    avg=$(echo "scale=2;$sum/$i"|bc -l)
    echo sum so far is $sum
    echo avg  so far is $avg
    done
    if [ -z "$SECONDS" ]; then echo "SECONDS variable not present so cannot report time elapsed"; else echo "time elapsed is '$SECONDS'"; fi
    also I will try formatting using http://stackoverflow.com/questions/6...n-neat-columns

    can you spot error in template.bat ?
