Shell Programming and Scripting

Hi,

I have to write a program to compare 2 files for copying.

the program is ran on Solaris 5.8 like this:
script.sh file1.txt file2.txt

I wrote the program using bash and it took me forever since I am a beginner but it works very well.

I'm getting so close to the deadline and I realised today that actually I have to use normal Bourne shell (bin/sh) and not bash(bin/bash).

Could anyone PLEASE help me to adjust my script (like replacing arrays..) I'm just getting so desperate....

I just attach a file with the script and also 2 little text files to run the script.

PLEASE HELP me anyone! Thank you so much!

I think you will have less work changing your logic than adapting your script to sh.
Try something like this :

Code:

File1=$1
File2=$2

Work=/tmp/`basename $0`.$$
Work1=$Work.1
Work2=$Work.2

tr -d '[:blank:]' < $File1 | sort -o $Work1
tr -d '[:blank:]' < $File2 | sort -o $Work2

LINES_MATCHING=`comm -1 -2 $Work1 $Work2 | wc -l | awk '{print $1}'`
LINES_TOTAL=`wc -l $Work1 | awk '{print $1}'`
LINES_NOT_MATCHING=`expr $LINES_TOTAL - $LINES_MATCHING`
PERCENT_NOT_MATCHING=`expr $LINES_NOT_MATCHING \* 100 / $LINES_TOTAL`

rm -f $Work1 $Work2

echo "Matched: $LINES_MATCHING"
echo "Not Matched: $LINES_NOT_MATCHING  ($PERCENT_NOT_MATCHING%)"
echo "Total: $LINES_TOTAL"

That's what I thought, I just have to change it all....... short night ahead....!
