Xnew_from_cat = torch.cat((x, x, x), 1) print(f'{xnew_from_cat.size()}') print() # stack serves the same role as append in lists It doesn't change the original # vector space but instead adds a new index to the new tensor, so you retain the ability # get the original tensor you added to the list by indexing in the new dimension An essential difference between cat and print is the class of the object they return This difference has practical consequences for what you can do with the returned object. I am a windows user having basic idea about linux and i encountered this command Cat is a unix command, not available on windows
Openssl is also not going to be available as a command. The original order is in fact backwards Certs should be followed by the issuing cert until the last cert is issued by a known root per ietf's rfc 5246 section 7.4.2 this is a sequence (chain) of certificates The sender's certificate must come first in the list Each following certificate must directly certify the one preceding it Cat filename | grep regex normally cat opens file and prints its contents line by line to stdout
After that grep reads from pipe (it takes pipe as stdin) then if matches regex prints line to stdout But here there is a detail grep is opened in new shell process so pipe forwards its input as output to new shell process While cat does stand for concatenate, what it actually does is simply display one or multiple files, in order of their appearance in the command line arguments to cat The common pattern to view the contents of a file on linux or *nix systems is Cat <<\eof >>brightup.sh without quoting, the here document will undergo variable substitution, backticks will be evaluated, etc, like you discovered If you need to expand some, but not all, values, you need to individually escape the ones you want to prevent
