grep -v ^$PKGNAME$ $PKGD/pkg.old $PKGD/packages
I was playing chicken :)
The first breaks down this way:
string (not scanned by shell): '^'
variable: $PKGNAME
string (not scanned by shell): '$'
The second is a little more dicey - how does one know that the shell
won't get confused or upset by the final '$'? With the double-quotes,
the shell scans the string. Given your example, I think I'd prefer
using:
^${PKGNAME}$
because it forces the name upon the shell - prevents even more
confusion...

[Leaf-user] uninstall option for lrpkg
Running dachstein RC2 floppy version:
I'm try to add an uninstall option into
lrpkg.
I've added this code to
/lib/POSIXness/POSIXness.linuxrouter in the lrpkg() function.
# uninstall ()
{
f="$1"
FN_LIST="$(cat
$lrpkgpath/$f.list)"
for FN in $FN_LIST; do
rm
/$FN
done
}#
this in the case function,
#
-u ) uninstall "$2" "$3"
;;#
and this in the usage function:
#
eecho " -u: uninstall Uninstall package. (explude
.lrp)"#
Is this messy/incorrect/etc? I havevery
littleexp. coding shell scripts,
that's why i'm asking, although it seems to work
ok.
Also, what can I add to this to update the
/var/lib/lrpkg/packages file
to remove the named package from the
list?
