Neil will surely provide an adequate answer, however, if your needs
aren't too sophisticated, you could put together something like
$ cat logviewer.sh
#!/bin/bash
if [ -z "$1" ]; then
echo "Must specify package name!" >&2
exit 1
fi
p=`eix --only-names -e "$1"`
if [ -z "$p" ]; then
echo "$1: No matches found" >&2
exit 1
else
howmany=`echo "$p" | wc -l`
if [ "$howmany" -gt 1 ]; then
echo "Many packages with the same name, refine search string:" >&2
echo "$p" >&2
exit 1
fi
fi
c="/usr/portage/${p}/ChangeLog"
if [ -z "$EDITOR" ]; then
EDITOR=`which vi`
fi
"$EDITOR" "$c"
---------
You can also remove the "-e" from the eix line if you want approximate
matching (that will require you to specify the category almost always
though).
Hope this helps.
