Question: Question:
I have a shell that lists the filenames in a folder every 5 seconds as shown below.
for file in `ls /home/test/`; do
echo "${file}"
sleep 5
done
I don't want to run sleep 5
only at the end of the loop because I don't have to wait 5 seconds after displaying the last filename, how do I write it?
Answer: Answer:
I'm a entangler, but I try to sleep for 5 seconds before evaluating echo.
If you don't sleep the first time, you'll exit the loop after the last one ends.
count=0
for file in `ls .`; do
#最初の1回はスリープしない。
if [ $count -ne 0 ]; then
sleep 5
fi
echo ${file}
((count++ ))
done
