Error with a variable and a loop

coreycollins · #1 (**permalink**) 02-09-05, 14:14

I'm writing a basic shell script to just read a file from the bottom line up. It will read each line, line by line then it will execute the line from the file. I currently am just trying to have it print out each line and I am getting an error running my program.

I am getting an error on line 5 which is my while loop like. My count value is currently 306 and I get an error saying: ./rebuildall.sh[5]: 306: not found.

Any ideas. My code is below. I know I am missing something simple.

Thank you

Code:

#!/bin/sh                               
#echo $1                                
count=`wc -l test.out | cut -c1-8`      
count=`expr $count + 0`                 
while ($count >= 0)                     
do                                      
  #echo $file_length                    
  line=`head -$count test.out | tail -1`
  echo $line                            
  count = `expr $count - 1`             
done
