If you have a laptop with APM installed, try the following PROMPT_COMMAND to create an environment variable ${battery} you can add to your prompt. This will indicate if AC power is connected and percentage power remaining. AC power is indicated by a "^" (for on) and a "v" (for off) before the percentage value.
function prompt_command { # As much of the response of the "apm" command as is # necessary to identify the given condition: NO_AC_MESG="AC off" AC_MESG="AC on" APMD_RESPONSE="$(apm)" case ${APMD_RESPONSE} in *${AC_MESG}*) ACstat="^" ;; *${NO_AC_MESG}*) ACstat="v" ;; esac battery="${temp##* }" battery="${ACstat}${battery}" } |
