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
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?
This should get you close... if you want only the top 10 just add more
pipes to the end with sort and head...
----------------------------------------------------
#!/bin/sh
newline='\
'
pkg_info -as | \
tr '\n' ' ' | \
sed -e 's/Package Size://g' \
-e "s/(1K-blocks)/$newline/g" |\
sed -e 's/^ *Information for //'
----------------------------------------------------
