RUNAT(1)

✨ NAME ✨

okay so this is RUNAT(1) from the General Commands Manual, and it's all about runat — literally run a shell command on a named attribute directory 🫶

🌸 SYNOPSIS 🌸

runat [file] [shell command]

🦋 DESCRIPTION 🦋

bestie, runat runs the shell command on the named attribute directory for the file argument. It does a fchdir(2) system call to change the current working directory into the named attribute directory for the file argument, and then it performs the shell command via sh(1) ✨

If a named attribute directory does not exist for file, an empty one will be created. 🫶

If an application needs to determine if a named attribute exists for the file, pathconf(2) with the name _PC_HAS_NAMEDATTR may be used. And this is important: this will not create an empty named attribute directory if one does not exist for file. 💅

🎀 EXAMPLES 🎀

for a file called “myfile”, it's giving:

$ runat myfile ls -l                    # lists the attributes for myfile
$ runat myfile cp /etc/hosts attrhosts  # creates attrhosts
$ runat myfile cat attrhosts            # displays contents of attrhosts
