Question

Imagine that you have to create many lines in file all with the same text except for one variable:

foo text $variable bar text
foo text $variable bar text
foo text $variable bar text
...

I was wondering if this could be made using a bash script passing it the variable as an argument:

./my_script '1'
./my_script '2'
./my_script '3'

Which would generate this:

foo text 1 bar text
foo text 2 bar text
foo text 3 bar text

Any suggestions or examples on how to do this?
