I am needing a bit of help. I am converting some of my old crontab entries to xxx.timer and xxx.service systemd files. I have the following (the system is a backup server that can be woken by magic packets or some amount of time before the backups run):
ExecStart=/usr/sbin/rtcwake -m mem -t $(/usr/bin/date +%s -d 'today 23:50') > /dev/null
It yeilds:
Invalid escape sequences in line, correcting: "/usr/sbin/rtcwake -m mem -t $(/usr/bin/date +%s -d 'today 23:50') > /dev/null"
Is there a way to correct this easily, or am I going to have to turn that line into a separate shell script?
Thank you.

SystemD executes the binaries directly without a shell so you can't use shell variables and such. You could write a script or I think prepending /usr/bin/bash on the front may work. You may need to put the commands in quotes. Google should find you an example.
Thanks, Richard
Thank you, Richard. you answered another question I had about one. I can now fix all of my cronjobs to be .service/.timer pairs.
