When I put these commands in: HOME=2 HOME='expr $HOME "+" 1' echo $HOME The result is just the echo: expr $HOME "+" 1 I want it to define $HOME as 3. All the example scripts show that my command should have worked! Getting frustrated because the a script I'm trying to make won't work. http://unix.about.com/library/course/blshscript-l7a.htm http://www.ss64.com/bash/expr.html |

You need 'back ticks' The are just to the left of the number one on the keyboard. HOME=2 HOME=`expr $HOME "+" 1` echo $HOME |
