bashrc syntax (SOLVED)

okplayer02 · 2008-12-06 14:10:18

say for instance id like to add an alias to my bashrc

say like

alias removeallpa='su -c pacman -Rs'

so that i can use pacman to remove a file
what is the correct syntax for the command to get it working properly

i know on the command line when i run

su -c 'pacman -Rs firefox'

it works perfectly it prompts me for the password like i want
i just prefer not to use sudo any guidance how to get this to work i would appreciate thanks

ah yes it did work perfectly the syntax now how can i go about typing the particular command like

supac firefox

obviously i will be using other programs other than firefox

it seems like i will have to use sudo to get around this problem but just looking for another solution

You could use a function.

function supac
{
    su -c 'pacman -Qi $@'
}

I think that should work for you.

u_no_hu · 2008-12-06 15:53:17

alias supac="su -c 'pacman -Qi "

you will have to fill in the other quote while running the command ;-) supac firefox'

and i dont know what will happen to other aliases if they are coming after this ... unchartered territory use at your own risk;-)

ah i see i will give a test try

so for my alias it would be like so

alias supac="su -c 'pacman -Qi'"

and as u explained with the next function it will define the alias if im correct?

function supac
{
    su -c 'pacman -Qi $@'
}

i dont mind cause im getting a lesson now i wasnt planning but i appreciate the help guys i take all disclaimers of course.

u_no_hu · 2008-12-06 16:07:33

dont close the single quote ... i feel terribly ugly recommending this......

okplayer02 · 2008-12-06 17:19:46

well i made a few adjustments to that function

function supac
{
    su -c 'pacman -Rs $@'
}

when i run

supac

it prompts for password then proceeds to list every package but if i do

supac firefox

it prompts for password then give the following message:

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

like i say i seen this with sudo but surely it must be the same for su -c
must be an way to get it working though i been looking at other examples but nothing so far

I think the '$@' doesn't get expanded because it's enclosed in single quotes.

This seems to work:

function supac {
  eval su -c \'pacman -Rs "$@"\'
}

okplayer02 · 2008-12-06 20:33:26

well yes that did thanks it is solved

thanks for that last tip

Ah crap, foiled by single quotes.

On the other hand, I don't think you really need to quote $@ in this instance, so this should probably work too:

function supac {
  su -c "pacman -Rs $@"
}

sudo?

And if you want to error with no args:

function omgwtf() {
   if [ $# -eq 0 ]; then
      echo "usage: omgwtf <packages to remove>"
   else
      su -c "pacman -Rs $@"
   fi
}
