Does anyone actually use
touchfor its intended purpose? Must be up there withcat.Ahhhhh, fuck. I'm quite noob with linux. I got into some rabbit hole trying to read the docs. I found 2 man pages, one is cat(1) and the other cat(1p). Apparently the 1p is for POSIX.
If someone could help me understand... As far as I could understand I would normally be concerned with (1), but what would I need to be doing to be affected by (1p)?
If you execute a binary without specifying the path to it, it will be searched from the $PATH environment variable, which is a list of places to look for the binary. From left to right, the first found one is returned.
You can use
which catto see what it resolves to andwhereis catto get all possible results.If you intentionally wants to use a different binary with the same name, you can either directly use its path, or prepend its path to $PATH.
