Package: dlocate
Version: 1.02
Followup-For: Bug #563881
Some pro-multiple package name syntax observations...
Several 'dlocate' options can't handle 3 or more package names. The
options '-ls', '-lsconf', '-du', '-md5sum', '-md5check', '-man',
'-lsman', '-lsconf', & '-L' all concatenate package names with 8
colons, (given 3 packages "foo bar baz"), and return the error:
Package bar::::::::baz not installed or bar::::::::baz.list is empty.
Some of the same options work correctly with 2 package names, for example:
% dlocate -man dash bash
1 dash
1 sh
1 bash
1 bashbug
1 clear_console
1 rbash
7 bash-builtins
The maintainer deprecates the syntax:
...that would require changing the output format (otherwise you'd have
no way of knowing which man pages belonged to which package) ...
...it can be can fed it into 'xargs man', like so:
'dlocate -man dlocate | xargs man'
Yet 'dlocate -man dash bash | xargs man' works OK. The "which is which"
question can be solved for free by the user deliberately invoking
'dlocate' with just one package name.
Sometimes it doesn't matter which package is which, as with this 'grep'
survey:
# survey two packages INIT Default-Stop settings
% dlocate -L setserial ipmasq | grep init.d/ | xargs grep 'Default-Stop'
/etc/init.d/setserial:# Default-Stop:0 6
/etc/init.d/etc-setserial:# Default-Stop: 0 6
/etc/init.d/ipmasq:# Default-Stop: 0 1 6
/etc/init.d/ipmasq-kmod:# Default-Stop:
The '-L [packages...]' syntax saved writing a loop.
Faking it: 'parallel', found in the 'moreutils' package, makes it
easier to fake multiple arguments:
# single (serial) task with '-j 1'
% parallel -j 1 dlocate -L -- setserial ipmasq dbus | grep init.d/
/etc/init.d/setserial
/etc/init.d/etc-setserial
/etc/init.d/ipmasq
/etc/init.d/ipmasq-kmod
/etc/init.d/dbus
So the many packages per line functionality can be had either way.
Built-in would not be all bad tho'.
HTH...
