bash files

Asked by Brad Ganson on 2010-08-13

have created a bash file to update alsa _.0.21 to alsa_1.0.23 for Ubuntu 10.04.
why...after i run it as executable with ./ in terminal mode is the file erased. i wrote it with gedit and saved to /home.
and how can I attach it here so everyone can use it if they need to upgrade to latest sound driver.

how do I send it?

Just paste the text.

Should only really be one line:

sudo add-apt-repository ppa:ricotz/unstable; sudo apt-get update; sudo apt-get upgrade

Try to change the

rm -rf ~/alsa* ~/.pulse*


rm -rf ~/.alsa/* ~/.pulse/*
rmdir .alsa .pulse

or to

rm -rf ~/.alsa ~/.pulse

Prior to this change if your script begins wirh "alsa" it will match the pattern "ΒΈ/alsa*", which should be the source of the problem.
Did a similar thing once in a script that was supposed to be a backup application.

The f isn't needed.

rm -r

is quite sufficient.

i saw these instructions at the following website:
rm -rf ~/alsa* ~/.pulse*
i presume means delete all files with the name alsa from my root directory.
if that is true what does rm -r mean?

rm will delete a file only, or empty a folder.
rm -r is a recursive delete and will basically delete the folder too.
rm -f will FORCEFULLY delete the folder and ca cause issues if files in the folder are open. If you know the files are not used then -f is not needed and using -f as a normal option is a REALLY *BAD* habit to form.

Force should only be used when needed, not every time.
