a simple question, can I create a file at a location I want & using cat command & without using pipes & and the location is some other place than I where I am currently. (I would appreciate an edit)

$ cat > location/i/want/theFileImCreating

cat doesn't really create files. It just writes to its standard output. In the above command, it's the output redirection (>) (set up by the shell) that creates the file (or empties an already existing one).

By default, redirections (>) clobber the target if it exists. If you want to prevent that, set -o noclobber is your friend.

If you don't want to fill the file with anything, touch will create a new empty file (or update the timestamp on an existing one).

If you want to strictly "create" a new file, including its path, a helper shell function/script might come in handy:

  while (( "$#" )); do
   [ ! -f "$1" ] && {
      mkdir -p "$(dirname "$1")";
      touch "$1";  
   }; shift


$ fcreat location1/i/want/file1 location2/i/want/file2
$ tree
$ tree
├── location1
│   └── i
│       └── want
│           └── file1
└── location2
    └── i
        └── want
            └── file2

fcreat: I don't know if I'm becoming a Unix expert or if I'm just losing my ability to spell.

  • Thanks, location must exist though, cat can't create a directory right – Tolga Varol Jul 25 '15 at 0:15
  • That is correct. – PSkocik Jul 25 '15 at 0:18

    @PSkocik - thank you. mine was screwed up. Yours is better. But can you do me a favor? I think theres a basic misunderstanding about who is responsible for the pathname creation. Just make it clear that cat is not in any way involved, please? – mikeserv Jul 25 '15 at 0:38

    I'd have used "for i; do ... stuff with $i; done" for looping over the arguments rather than while/shift. – Random832 Jul 25 '15 at 5:38
