How do i create a new file using the cat command?
-
One of the wonderful things about Linux and Unix is there are a number of ways of doing a task to achieve the same result.
If you need to do a quick simple script without going into editors, you can use the cat command.
$ cat > mytemp.sh last | grep reboot ^D $ chmod +x mytemp.sh $ ./mytemp.sh
If you use the same filename again using the above method, the content will be overwritten, but it's handy for running quick one-liners, that is usually longer than the example shown here.
