Writing variables to file with bash


I’m trying to configure a file with a bash script. And the variables in the bash script are not written in file as it is written in script.



printf "%s" "template("$DATE\t$HOST\t$PRIORITY\t$MSG\n")" >> /file.txt

exit 0

This results to template(‘tttn’) instead of template(“$DATE\t$HOST\t$PRIORITY\t$MSG\n in file.

How do I write in the script so that the result is template(“$DATE\t$HOST\t$PRIORITY\t$MSG\n in the configured file?

Is it possible to write variable as it looks in script to file?


Enclose the strings you want to write within single quotes to avoid variable replacement.

> FOO=bar
> echo "$FOO"
> echo '$FOO'
