cat > variable + format
I wanted to store a value read from a file in a variable with a given format. I was doing the first step as follows :

it0="$(cat ./myfile)"

I thought the second step would work as: it0= ` printf "%6.3f\n" $it0 `

but it says "./curplot.sh: line 33: 0.035: command not found", although it raises the result as I want it (0.035). And the concatenation

Any idea?. Thanks in advance

Hi.

There should be no spaces on either side of the = sign.
