I am trying to use xargs command using shell pipes and not able to understand how to control and use command line arguments. For example I’d like to find out all *.c file located in 100s of sub-directories and move them to another directory called ~/old.src. How do I use command line args with xargs to achieve the same?

How do I pass all command line args to my bash alias called foo. For example: alias foo=”/path/to/command $@” However $@ get interpreted when creating the alias instead of during the execution of the alias and escaping the $ doesn’t work either. How do I solve this problem?
