Re: need help w/ simple bash script

Hiya.

I've been working on a web front-end to aggregate multiple servers'
package update requirements as well.  I'll probably have it ready to
present in another few weeks, if ${DAYJOB} doesn't get in the way.

 Xaw3d-1.5E_1 = up-to-date with port

Use more quotes.

  REPORT = `pkg_version -v`

will protect the newlines.

 for LINE in `pkg_version -v`; do echo $LINE; done

If you feel adventurous, you could to try something like this:

  tmpfile=/tmp/`basename $0`.$$
  trap rm -f $tmpfile $tmpfile.? 0 1 2 3 5 15
  pkg_version -v | while read package status text; do
echo $package $text  $tmpfile.$status
  done

Now you have tempfiles with package lists for the various stati, which
you can parse as you see fit.

Note that you may get better (i.e. more useful) mileage out of something
like:

  pkg_version -vL=

which will show you only what needs to be updated.

 Subject: need help w/ simple bash script
 
 Hi all,
 
 I am trying to write a simple bash script that will collate 
 pkg_version 
 reports from all of my servers to generate centralized HTML 
 reports. To 
 format the output, I am trying:
 
 # REPORT=`pkg_version -v`
 
 But when I echo $REPORT, I get:
 
 Xaw3d-1.5E_1 = up-to-date with port apr-db42-1.2.7_1 = 
 up-to-date with 
 port autoconf-2.13.000227_5 = up-to-date with port autoconf-2.59_2 = 
 up-to-date with port automake-1.9.6 = up-to-date with port 
 bash-3.1.17 = 
 up-to-date with port cvsup-without-gui-16.1h_2 = up-to-date with port 
 db41-4.1.25_3 = up-to-date with port.
 
 When what I want is:
 
 Xaw3d-1.5E_1 = up-to-date with port
 apr-db42-1.2.7_1 = up-to-date with port
 autoconf-2.13.000227_5 = up-to-date with port
 autoconf-2.59_2 = up-to-date with port
 automake-1.9.6 = up-to-date with port
 bash-3.1.17 = up-to-date with port
 cvsup-without-gui-16.1h_2 = up-to-date with port
 db41-4.1.25_3 = up-to-date with port
 ...
 ...
 ...
 
 
 I've also tried:
 
 for LINE in `pkg_version -v`; do echo $LINE; done
 
 but that's even worse; then I get:
 
 Xaw3d-1.5E_1
 =
 up-to-date
 with
 port
 apr-db42-1.2.7_1
 =
 up-to-date
 with
 port
 autoconf-2.13.000227_5
 =
 up-to-date
 with
 port
 autoconf-2.59_2
 =
 up-to-date
 with
 port
 ...
 ...
 ...
 
 I know I figured out a technique once before, but I'm banging my head 
 against a wall right now. Thanks for any help.

why not just try

pkg_version -v |while read h_line
do
echo $h_line TO SOMEWHERE
done;


you'd be even able to do something like
pkg_version -v |grep -v 'up-to-date with port'|while read h_line
do
blah
done;


have fun ;-)
