show dots when script is "thinking"

Shell Programming and Scripting
1

Hey, I'm running the following script:

#!/bin/bash

kjv=kjv.txt
trim(){
    local trim_string
    local _TRIM=$1
    trim_string=${_TRIM##*[${2:- }]}
    _TRIM=${_TRIM#"trim_string"}
    echo $_TRIM
}

#trim() {
#    echo $( _trim "$@" )
#}

printf "How many chapters? "
read response

while IFS=: read book chapter verse text
do
    #this is a temp variable!
    chapterCount=$response
    chapterNumber=$( trim "$chapter" 0 )
    if [ $chapterNumber -le $chapterCount ]
    then 
        firstword=${text%% *}
        printf "%s %s:%s %s\n" "$book" "$chapter" "$verse" "$firstword"
    fi
done < "$kjv"
printf "\n"

Basically it takes the first word out of each verse of a specified amount of chapters from a text file. Since the file is so large it takes some time and sometimes looks like its stuck. How can I add dots (periods) or something of that nature every time it's "thinking"?

line_count=0
blocksize=1000
while IFS=: read book chapter verse text
do
    line_count=`expr $line_count+1`
    if [ $line_count -gt $blocksize ]
      then 
         echo ".\c"
         line_count=0
     fi
    #this is a temp variable!
    chapterCount=$response
    chapterNumber=$( trim "$chapter" 0 )
    if [ $chapterNumber -le $chapterCount ]
    then 
        firstword=${text%% *}
        printf "%s %s:%s %s\n" "$book" "$chapter" "$verse" "$firstword"
    fi
done < "$kjv"

Some systems need "echo -e"
Adjust blocksize to suit.
You may have to adjust the output of the printf to go to a file, depending on how the script is called

#  Make an array of the aforementioned eye candy... 
integer n=${#Indicators[@]}
integer i=0

#  While condition exists, present status to screen... 
while [[ -f bpc.txt ]] 2>/dev/null #true
do
   clear 
#   print -n -- "Running ... \n\t${Indicators}\n"
   print "Running ... \n\t${Indicators}\r"
   ((i=(i+1)%n))
#  sleep 1
#  clear
done

Note that you'd want to modify the condition that drives the while... loop.

What are all those block-characters in the print statement?

Instead of clearing the screen every time, try printing a carriage return instead of a newline. It will overwrite the last busy line with the next one.

hey, you're right...

So now I have:

#!/bin/bash

kjv=kjv.txt
trim(){
    local trim_string
    local _TRIM=$1
    trim_string=${_TRIM##*[${2:- }]}
    _TRIM=${_TRIM#"trim_string"}
    echo $_TRIM
}

#trim() {
#    echo $( _trim "$@" )
#}

printf "How many chapters? "
read response

line_count=0
blocksize=1000
while IFS=: read book chapter verse text
do
    line_count=`expr $line_count+1`
    if [ $line_count -gt $blocksize ]
      then 
         echo ".\c"
         line_count=0
     fi
    #this is a temp variable!
    chapterCount=$response
    chapterNumber=$( trim "$chapter" 0 )
    if [ $chapterNumber -le $chapterCount ]
    then 
        firstword=${text%% *}
        printf "%s %s:%s %s\n" "$book" "$chapter" "$verse" "$firstword"
    fi
done < "$kjv"

and i get the following error:

integer expression expected

which is the line:

if [ $line_count -gt $blocksize ]
7

spaces are important.

line_count=`expr $line_count + 1`

Sorry, my heart was in the right place, but my syntax wasn't

8

hmm still not working

9

That's not much help; in what way is it not working?

10 
#!/bin/bash

kjv=kjv.txt
trim(){
	local trim_string
	local _TRIM=$1
	trim_string=${_TRIM##*[${2:- }]}
	_TRIM=${_TRIM#"trim_string"}
	echo $_TRIM
}

#trim() {
#	echo $( _trim "$@" )
#}

printf "How many chapters? "
read response

line_count=0
blocksize=1000
while IFS=: read book chapter verse text
do
    line_count - `expr $line_count + 1`
    if [ $line_count -gt $blocksize ]
      then 
         echo ".\c"
         line_count=0
     fi
    #this is a temp variable!
    chapterCount=$response
    chapterNumber=$( trim "$chapter" 0 )
    if [ $chapterNumber -le $chapterCount ]
    then 
        firstword=${text%% *}
        printf "%s %s:%s %s\n" "$book" "$chapter" "$verse" "$firstword"
    fi
done < "$kjv"

returns the following error:
/home/administrator/bin/pk8-1-test: line 27: line_count: command not found

11

As I see it, the problem is at line 23, not 27.

line_count - `expr $line_count + 1`

and at line 32 (testing result of call to trim function), which doesn't return anything.
