while loop stops after a function...
my ksh script is not working...
i wanna remove lines in file2.txt from file1.txt
Code:
# cat file1.txt
this is line one 
this is line two
this is line three
this is line four
this is line five

# cat file2.txt
this is line two
this is line three

# cat my_script.ksh
#!/bin/ksh

i=1
y=1
myfunc()
{
exec < file1.txt
while read line ; do
file1[i]=$line
if [[ ${file1[i]} = ${arr2[y]} ]] ; then
echo ${file1[i]} and ${file2[y]} are the same.
sed ''$i'd' file1.txt > new.txt
mv new.txt file1.txt
else
echo ${file1[i]} and ${file2[y]} are not the same.
fi
(( i=i+1 ))
done
return
}
exec < file2.txt
while read line2 ; do
file2[y]=$line2
myfunc     # calling the function
(( y=y+1 ))
done
cat file1.txt
