Question

can someone help me spot the problem here ?

#!/bin/sh

find . -name '*ABC*' > replace_temp.file
num_of_lines=`cat replace_temp.file | wc -l`
i=0
while $i<$num_of_lines
do
   tc=`expr $i + 1`
   line=`tail -$tc replace_temp.file |head -1`
   line1=$line
   sed -e 's/\(.*\)ABC/\1DEF/' $line
   #mv -f $line1 $line   
done 
#rm -f replace_temp.file

i get the error replace.sh: line 6: 20: No such file or directory

purpose of this script: search and replace all files directories containing ABC in their name to DEF

it goes through the lines of find results file from bottom to top so there wont be any problems with dir dependencies (eg changing name of one dir will mess up changing the name of it’s sub dir)

thanks

Answer 1

while $i<$num_of_lines

should be something like

while [ $i -lt $num_of_lines ]

or if you insist

while (($i < $num_of_lines))
