Assign the output of command to variable [duplicate]

Question

I have to cut the string after the white-space and store the value before white-space. My example script is show below

tString="This is my name"
echo $tString | cut -d' ' -f1

output:

This

Now I want to assign this output value to the variable. My script is

tString="This is my name"
var=$($tString | cut -d' ' -f1)

It shows error.Error message is

This: command not found

Iam new to bash shell script. Anyone Knows how to do this.

Besides, you don't need this complex command. read var unused <<< $tString will also serve the purpose. — anishsane

Sorry, it should have been read var unused <<< "$tString" , else it may give errors on some bash'es... — anishsane

Add an echo:

tString="This is my name"
var=$(echo $tString | cut -d' ' -f1)
