minus-squaredan@upvote.aulinkfedilinkarrow-up13·edit-21 day agoAdmittedly I still use cat for this. This also works too, but it’s more verbose: echo "$(<foo.txt)" It’s mentioned in the Bash man pages: The command substitution $(cat file) can be replaced by the equivalent but faster $(< file). EDIT: I was just informed that simply <foo.txt works too.
