For more than 3 decades I've just used "df -k". OK, even on smaller disks than yours, that's a lot of digits, so a bit of mental juggling: $ df -k Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda9 293477416 15376432 263193184 6% /home Better is "df -m". On larger disks, you'll have more digits than here: $ df -m Filesystem 1M-blocks Used Available Use% Mounted on /dev/sda9 286600 15017 257025 6% /home > Of course I can fire up bc, set scale=20 and do some > powers of 1024 division, but that's all very clunky. > > How hard would it be to add an option to bc, to choose the number of > decimal places to use in the output, or the number of digits of > precision to display? Harder than putting the output of df -k through two lines of awk in a shell function, I figure. Erik
