The common pattern to view the contents of a file on Linux or *nix systems is: cat <file> The main difference between cat and Git's cat-file is that it only displays a single file (hence the -file part). Git's cat-file doesn't ...
46 There are a few ways to pass the list of files returned by the find command to the cat command, though technically not all use piping, and none actually pipe directly to cat. The simplest is to use backticks (`): cat `find [whatever]` This takes the output of find and effectively places it on the command line of cat.
