Hi. I am writing up a doc for the fbsd community that covers usage of ports. I have two commands that allow me to assertain the amount of disk space being utilized by currently installed ports. I would like to make a shell script (bourne or bash) out of them but I am not sure how. 1. This gives me the amount of space (kB) taken up by the 10 largest ports: $ pkg_info -as | grep ^[0-9] | sort -gr | head -10 | cut -c 1-6 Example output: ------------------------------------------------------ 240695 59274 55526 54271 47418 42644 35364 31091 29181 28745 ------------------------------------------------------ 2. Using one figure from above list I produce the details of the corresponding port: $ pkg_info -as | grep -B3 240695 Output: ------------------------------------------------------ Information for linux_base-8-8.0_6: Package Size: 240695 (1K-blocks) ------------------------------------------------------ I would like the output of the script to be the above but for all ten ports (~40 lines; insert a blank line between each?). I know I need some sort of iteration but I am rusty on scripting. Can anyone help? __________________________________________________________ Find your next car at http://autos.yahoo.ca
