echo "Here I am in $var1 selling ties": does not do what I expect.

Bash 3.1.7

Hi:

Code:

#!/bin/bash

#         

file=$1
infile=$1".cue"
FIRST=1

while read A1 A2 A3            # TRACK 08 AUDIO
do
if [ "$A1" == "TRACK" ] 
then 
        read A1 A2             # TITLE "Piano ..........."
        read A1 A2 A3          # INDEX 00 40:18:43
#       echo $A3               # 40:18:43

        old="$new"
        new="$A3"
        if [ $FIRST == 1 ] 
        then
                FIRST=0
        else
                # Here new is 08:28:10
                echo "Here I am $new waiting"
        fi               
        echo ----------------
fi
done < "$infile"
echo "flac --skip="$new
exit

The output is

Code:

----------------
 waitingm 62:36:67
 until=decode --skip=53:40:73
----------------
 waitingm 65:53:13
 until=decode --skip=62:36:67
--

But it should be Here I am 08:28:10 waiting. I have tried in a thousand different ways and always 'waiting' overwrites the string. What am I doing wrong?

Part of the input file is

Code:

 TRACK 09 AUDIO
    TITLE "Piano Sonata No.19 in G minor, op.49 no.1 - II. Rondo. Allegro"
    INDEX 01 43:53:30
  TRACK 10 AUDIO
    TITLE "Piano Sonata No.20 in G major, op.49 no.2 - I. Allegro, ma non troppo"
    INDEX 00 47:21:58
    INDEX 01 47:29:33 # --> new

It's probably because the file uses "\r\n" Windows line endings rather than "\n" Unix line endings and you're reading that \r into the var. As such, it is actually printing "Here I am 08:28:10\r waiting", and \r resets the cursor back to the start of the line (carriage return).

Well, it works here. I just saved your script to test.sh and the sample data to input.cue. I run it:

Code:

$test.sh input
----------------
Here I am 47:21:58 waiting
----------------
flac --skip=47:21:58

The only difference is that I'm running bash 4.1. Maybe that's the problem, but I'm not sure.

Lo and behold! The input file is a DOS style file. Diantre's suggestion turned out to be true!

Ehem! *cough*... It was actually @tuxdev who suggested it. Glad you got it working though.

You are right.
