Bash: Get The Last Argument Passed to a Shell Script

Posted on in Categories last updated June 26, 2012

I‘m writing a bash wrapper script that will pass arguments to the command. I need to find out the last argument if I call the wrapper as follows:

./wrapper -a -b –longarg=foo thisfilename.txt
./wrapper -a -b thisfilename.txt
./wrapper -a –next=true thisfilename.txt

=> $@ is all of them.
=> $0 is script name.
=> $1 is first arg.

I want thisfilename.txt stored in a shell variable called $last. How do I find the last argument passed to a shell script written in bash or ksh under Unix like operating systems?

Where Is The Xorg.conf File Located under Unix / Linux / BSD?

I want to find and edit my xorg.conf file for tweaking and configure it for new settings. The problem is that I’m unable to find the file. According to my research, xorg.conf should in /etc/X11 or /usr/X11R6/lib/X11/ directory. I found directories but not the file in directories. How do I find the xorg.conf under Unix or Linux like operating systems?
