I want to run a script without using cron at specific time. But it is not working.
#!/bin/sh DATE=`date | cut -d' ' -f4` #Date is getting printed, if I run it manually, without any error. But file is not created at scheduled time. echo $DATE if [[ $DATE == "07:06:55" ]] then echo "this is a test program" >> xyz.log fi
If you want to run it only once, you can use the at command : https://en.wikipedia.org/wiki/At_(command)
Example :
echo "echo \"this is a test program\" >> /tmp/xyz.log" | at 1127 apr 11
If you want to run it every day, you might need to use a loop :
#!/bin/bash while true; do DATE=`date | cut -d' ' -f4` echo $DATE if [[ $DATE == "11:33:00" ]] then echo "this is a test program" >> xyz.log sleep 1s fi done
