So I am the proud owner of a weather cape and beagle bone white and a newb when it comes to bash scripting. Lets say I want to otput to the command line the relative humidity as a percentage using a bash script. Getting the relative humidity is as easy as cat /sys/bus/i2c/devices/1-0040/humidity1_input How do I assign this value to a variable in a bash script so that I can manipulate it (specificall divide by 1000 to express as a percentage)? humidityInput=/sys/bus/i2c/devices/1-0040/humidity1_input echo $humidityInput gives me /sys/bus/i2c/devices/1-0040/humidity1_input I have tried putting paranthesis, quotes, and single quotes around "/sys/bus/i2c/devices/1-0040/humidity1_input" but can't get bash to assign the value of the file to the variable. Any of you linux gurus want to help a new out? Thanks in advance! Jason
