Hello, I'm going to write a shell function that
provides a basic functionality(print the content of a file or
stdin) of cat[0], in order to avoid forking too many process when
I call it in a loop[1].
I try to avoid cat alltogether, as many uses belong to the "Useless
use of cat" category, like this one:
$ cat archlinux-2012.09.07-dual.iso | wc -c
39
Could also be "wc -c archlinux-2012.09.07-dual.iso".
Results in mostly cat-free shell scripts (I like dog(s) more, anyway
;-) )
