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?
I‘m using a Mac OS X and combination of ssh-agent+ssh-add to adds RSA or DSA identities to the authentication agent. ssh-agent provides me a secure way of storing the private key.

How do I run “foo” command 10 times (or n times) under Linux or UNIX like operating systems?
I have a file of that looks as follows:
Each word and/or Linux is a different length. How do strip or remove the last character from each line using bash or ksh shell only?
