Question:
How would you print just the 10th line of a file?
For example, assume that file.txt
has the following content:
Line 1
Line 2
Line 3
Line 4
Line 5
Line 6
Line 7
Line 8
Line 9
Line 10
Your script should output the tenth line, which is:
Line 10
hint:
- If the file contains less than 10 lines, what should you output?
- There's at least three different solutions. Try to explore all possibilities.
Solution:
IFS=$'\n'
count=1
for line in `cat file.txt`
do
if [ $count -eq 10 ]
then
echo $line
fi
count=$[ $count + 1 ]
done
