Get string after character [duplicate]

Question

I have a string that looks like this:

 GenFiltEff=7.092200e-01 

Using bash, I would like to just get the number after the = character. Is there a way to do this?

Answer 1

Use parameter expansion, if the value is already stored in a variable.

$ str="GenFiltEff=7.092200e-01" $ value=${str#*=} 

Or use read

$ IFS="=" read name value <<< "GenFiltEff=7.092200e-01" 

Either way,

$ echo $value 7.092200e-01
