How to set a variable to the output of a command in Bash? 13 answers

As the others said you need to capture the output from the commands.

z=echo foo -bash: foo: command not found

is not the same as

z=$(echo foo)

In the first one it's equivalent to

z=echo foo

which is not valid as it thinks foo is a command.

z=$(echo foo) however means to execute echo foo and capture the output into z .

All of your commands fail to do this.
