Reinstall the installed packages

hi

I have dual boot system Ubuntu + Arch linux and I wanted to configure arch through chroot. unfortunatly I forgot to mount /dev and /proc so it got some errors during upgrade.

/tmp/alpm_xXzQ7F/.INSTALL: line 7: /dev/null: Permission denied

or

/sbin/mkinitcpio: line 253: /dev/null: Permission denied

I didn't start the system yet but I would like to reinstall packages if its posible. I found this  command

pacman -S $(pacman -Qq | grep -v "$(pacman -Qmq)")

and it returns

error: no targets specified (use -h for help)

which is not so strange cause 

pacman -Qmq

returns nothing which is strange

Any help would be apriciated.

Re: Reinstall the installed packages

The "target" for your command is missing, s/b:

pacman -S $(pacman -Qq | grep -v "$(pacman -Qmq)" >pkglist)

This command is used to generate a list of installed packages such that they can be re-installed by pacman:

#pacman -S $(cat pkglist)

....EDIT
This pkglist has to be accessed possibly through usb flash such that the re-install is accomplished for the packages in the pkglist.

Please google "re-install pacman packages" for more accurate info( my info from memory).

Your /var/cache/pacman/pkg may not contain the desired packages altho I have no reason to believe it won't.

You mean

pacman -Qq | grep -v "$(pacman -Qmq)" >pkglist

?

Re: Reinstall the installed packages

didn't read the whole thrad but... use -vx to match whole lines, otherwise you could omit package foo-bar if package foo happens to be foreign.

pacman -Qq | grep -vx "$(pacman -Qqm)" | xargs pacman -S

should reinstall your system.
