Bash - Using the AT command without a file

It might sound odd, but I need to run the AT command and schedule a command but I don't want to make a file and send it to AT with the -f option. Is it somehow possible to write the whole thing in one single line. Suppose I want to run the "gnome-terminal" at the time 13:10.

Thanks

Solution

  • at reads from standard input by default, i.e. if -f is not used. You can pass multiple lines in several ways, e.g. using here documents:

    at << EOF
first line
second line
EOF

    Or within a single line (specific to bash):

    at <<< $'first line\nsecond line'
