Python Piping 'type' question

Question

>> type countlines.py | python countlines.py 

Quelqu'un peut-il expliquer ce que "type" fait? Est-ce que cela ne fait que taper les composants du fichier? Impossible de trouver la documentation

Answer 1

Sur les fenêtres, 'type' est l'équivalent de la commande 'cat' sur Linux, et oui - il imprime simplement le contenu du fichier.

Answer 2

Sur la page man bash:

 
type [-aftpP] name [name ...] 
       With no options, indicate how each name would be interpreted if 
       used as a command name. If the -t option is used, type prints a 
       string which is one of alias, keyword, function, builtin, or 
       file if name is an alias, shell reserved word, function, 
       builtin, or disk file, respectively. If the name is not found, 
       then nothing is printed, and an exit status of false is 
       returned. If the -p option is used, type either returns the 
       name of the disk file that would be executed if name were speci‐ 
       fied as a command name, or nothing if ``type -t name'' would not 
       return file. The -P option forces a PATH search for each name, 
       even if ``type -t name'' would not return file. If a command is 
       hashed, -p and -P print the hashed value, not necessarily the 
       file that appears first in PATH. If the -a option is used, type 
       prints all of the places that contain an executable named name. 
       This includes aliases and functions, if and only if the -p 
       option is not also used. The table of hashed commands is not 
       consulted when using -a. The -f option suppresses shell func‐ 
       tion lookup, as with the command builtin. type returns true if 
       all of the arguments are found, false if any are not found.
